This document discusses different types of interactions between organisms in an ecosystem. It defines interaction as a relationship between organisms that can affect their growth, survival, and reproduction. Interactions can be positive, like mutualism where both species benefit each other, or negative, such as competition where organisms of the same species compete for limited resources. Specific examples of positive interactions discussed are mutualism between plants and animals that help with pollination and seed dispersal. Negative interactions explained include parasitism, competition, and predation.
Interactions in a terrestrial ecosystem
Organisms interact in various ways that affect their survival. Ecologists classify interactions as competition, symbiosis, or predation. Competition occurs between members of the same species for limited resources. Symbiosis describes interactions between different species that can be mutualistic, commensal, or parasitic. Predation involves a predator killing a prey organism for food.
Ecology
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. A population is a group of the same species that lives in the same place and interbreeds. A community consists of interacting populations that share a common environment. An ecosystem includes both living populations and non-living environmental factors. Habitats provide resources and can be limited by factors like food, water, temperature or space. Feeding relationships include producers, consumers, predators, and parasites. Symbiotic relationships such as commensalism, parasitism, and mutualism vary in their effects on species.
Ecological Relationship
There are two types of ecological relationships: symbiotic and oppositional. Symbiotic relationships include mutualism, commensalism, amensalism, and parasitism, where species interact with varying levels of benefit and harm. Oppositional relationships involve predation, where one organism eats another for nutrients, and competition, where organisms compete for the same resources like lions and hyenas competing for prey. Ecological communities consist of interacting species that have relationships that can benefit, harm, or oppose each other in various ways within a shared environment.

Ecological relationship
This document discusses different types of ecological relationships between organisms including competition, predation, herbivory, and symbiosis. Competition occurs when organisms require the same limited resources. Predation is when one organism feeds on another. Herbivory describes a primary consumer feeding on a producer or another consumer. Symbiosis refers to long-term interactions where at least one organism benefits, and can be mutualism, commensalism, or parasitism.

This document discusses different types of biological interactions between species: mutualism, amensalism, commensalism, and parasitism. It provides examples for each type of interaction. Mutualism benefits both species, such as the relationship between plants and mycorrhizal fungi. Amensalism harms one species without affecting the other, like competition between trees and saplings. Commensalism benefits one species without affecting the other, exemplified by phoretic mites on insects. Parasitism benefits one species at the expense of the other, illustrated by tapeworms living in mammalian guts.
2.1.7
The document discusses several types of population interactions: neutralism where species do not affect each other; competition for limited resources between members of the same or different species; amensalism where one species is harmed while the other is unaffected; herbivory involving grazing; mutualism providing benefits to both species such as lichens; predation with one species preying on another; parasitism where one organism lives in or on another to obtain nutrients; and commensalism where one benefits while the other is not affected, as in orchids growing on tree branches.
Ecosystem
An ecosystem is a community where living things interact with and depend on each other and their environment. There are several types of biological relationships that exist between organisms in an ecosystem, including symbiosis, parasitism, mutualism, competition, predation, and commensalism. For example, ants live in plant stems for shelter and nourish the plant with droppings, while the plant benefits without being harmed.
Food Chains and Webs
The document discusses the roles of organisms in ecosystems, including producers, consumers, and decomposers. Producers such as plants make their own food through photosynthesis. Consumers obtain food by eating other organisms and can be primary, secondary, or tertiary consumers depending on what they consume. Decomposers like bacteria and fungi break down dead organic material and return nutrients to the soil. The document also defines food chains as simple representations of feeding relationships and food webs as more complex networks of interconnected food chains within an ecosystem.
Relationships among organisms
This document discusses three types of relationships between organisms:
1) Mutualism, where two organisms benefit each other, such as butterflies and flowers where the butterfly gets nectar and pollinates flowers.
2) Commensalism, where one organism benefits without affecting the other, like remoras eating scraps from sharks or orchids growing on trees.
3) Parasitism, where one organism harms the host to benefit itself, as in the case of aphids sucking the juices of roses.
Panjami lesson plan 8
The document discusses different types of ecological interactions that occur in nature such as predation, parasitism, competition, mutualism, and commensalism. Predation benefits one organism while harming the other, such as a tiger eating a deer. Parasitism also benefits one organism, the parasite, while harming the host. Competition can initially harm both organisms as they compete for resources, but eventually benefits the stronger organism. Mutualism provides benefits to both organisms, like flowers and butterflies. Commensalism benefits one organism without affecting the other, like mango trees providing shelter for vanda plants. These ecological interactions help maintain balance in ecosystems.
Ecosystem relationships
1. An ecosystem is composed of individual organisms that make up populations, several populations that make up a community, and the biotic and abiotic factors that make up the ecosystem. Ecosystems are found within different biomes, which together make up the biosphere.
2. An organism's habitat is the place it lives and provides its needs, while its niche is its role in the ecosystem including how it obtains food and interacts with other organisms.
3. Within an ecosystem, producers like plants use photosynthesis to make their own food, while consumers eat other organisms for energy as herbivores, carnivores, omnivores, or decomposers. Organisms engage in symbiotic relationships of
Community Interactions And Sucession
Community interactions such as competition, predation, and symbiosis shape ecosystems. Competition occurs when organisms seek the same resources, leading to winners and losers. Predation involves a predator killing and eating prey. Symbiosis describes close relationships between species, including mutualism where both benefit, commensalism where one benefits without affecting the other, and parasitism where one harms the host. Ecosystems constantly change through ecological succession as disturbances allow new species to establish over time through primary succession on new surfaces and secondary succession following disturbances.
Types of interactions
This document discusses different types of interactions between organisms and their environment. It explains that populations are limited by factors like food, water, space, and other resources. When populations exceed the carrying capacity of their environment, limiting factors cause deaths until the population stabilizes. The document also describes different ways organisms interact, including competition for resources, predator-prey relationships, symbiosis, and coevolution as species adapt to each other over long periods of time.
Biotic interactions
Biotic factors also regulate the size of populations more intensely. Finally, the influence of biotic interactions can occur at two different levels. Interspecific effects are direct interactions between species, and the intraspecific effects represent interactions of individuals within a single species.
Ecosystem and Organism Interactions
This presentation summarizes the major concepts about interactions of organisms while highlighting the ecosystem, competition, symbiosis and the ecological niche.
Relationships between living things page 6
This document discusses relationships between living things in an ecosystem. It defines key terms like species, population, and community and explains how they interact. It also outlines the different ways living things obtain food, including producers, primary consumers, secondary consumers, tertiary consumers, and decomposers. Finally, it introduces the concept of food chains to show how food transfers from one organism to another.
Ecology
Ecology is the scientific study of interactions between organisms and their environment. It includes the study of different levels of ecological organization from the biosphere down to individual organisms. Organisms fill different ecological niches as producers, consumers, or decomposers within food chains and food webs. Population growth follows exponential or logistic patterns depending on environmental carrying capacity. Succession over time leads to the development of climax communities.
animal plant interactions
Plants and animals interact in ecosystems through carbon dioxide and oxygen cycles. Plants take in carbon dioxide and release oxygen through photosynthesis, while animals breathe in oxygen and release carbon dioxide. Populations of living things in an ecosystem interact to obtain resources like food, water, and shelter. Animals depend on plants for food and shelter, while plants rely on animals to distribute seeds and provide nutrients when they die.
Biological interactions
This document discusses various types of biological interactions between organisms including competition, mutualism, commensalism, amensalism, parasitism, and predation. Competition occurs when organisms attempt to use the same limited resources, and can be intraspecific or interspecific. Mutualism benefits both species involved. Commensalism benefits one species without affecting the other. Parasitism benefits one species at the expense of the other. Predation involves a predator consuming another organism, the prey. Examples of each type of interaction are provided.
Interspecific relations
This document discusses different types of ecological relationships between living things:
Interspecific relationships include cooperative relationships like mutualism, competitive relationships where different species compete for resources, and exploitative relationships where one species uses another as a resource, such as through predation, parasitism, or herbivory.
Intraspecific relationships within species can include competition for resources or mates, cooperation for tasks like finding food or protecting young, and relationships around sharing reproduction or protection.
Interactions among organisms 2
This document discusses key concepts in ecology including different levels of ecological organization, abiotic and biotic factors, habitat and niche. It also describes different types of ecological relationships between organisms including mutualism, commensalism, parasitism, and predation. Examples are provided to illustrate each relationship type. The levels of ecological organization include the biosphere, ecosystem, community, population, and organism.
Ecological Succession and Community Interactions
Ecological succession describes the predictable changes in communities over time. Primary succession occurs on new surfaces without soil, while secondary succession follows a disturbance with existing soil. Succession proceeds through stages from pioneer species to a climax community. Invasive species can disrupt normal succession. Community interactions include predation, competition, mutualism, commensalism, and parasitism. Early successional communities have simpler structures and functions than late successional communities.
Interactions within ecosystems
This document discusses interactions between living things within ecosystems. It describes the five levels of organization within ecosystems from largest to smallest as biome, ecosystem, community, population, and organism. Patterns exist in populations related to living space and time. Population sizes change over time due to factors like predator-prey relationships, birth and death rates, limiting factors, and carrying capacity. Organisms interact through predation, competition, cooperation, and symbiosis. Ecosystems also change over time through ecological succession as one community replaces another.

The document discusses various types of interactions between species within ecosystems, including competition, predation, symbiosis, and coevolution. Competition occurs when different species or individuals attempt to use the same limited resources. Predator-prey relationships involve a predator that hunts for prey. Symbiosis describes close relationships between species, which may involve mutualism where both benefit, commensalism where one benefits and the other is unaffected, or parasitism where one benefits and the other is harmed. Through coevolution, species in close relationships can evolve adaptations over time that improve or reduce the impacts of these interactions.

Each relationship is defined based on whether it benefits, harms, or has no effect on the interacting species.
Ecosystems – interactions pdf
Ecosystems include all populations in an area and everything that affects them. Populations interact with their environment through limiting factors that control their size and carrying capacity. Communities consist of all species in an area that interact through competition for resources, predator-prey relationships, and adaptations like camouflage or group behavior. Symbiotic relationships involve close associations between species that can be mutually beneficial, benefit one species, or involve parasitism.
Chapter 21 and 22
The document discusses different types of species interactions including predation, mimicry, plant-herbivore interactions, parasitism, competition, mutualism, and commensalism. It also covers topics like producers and consumers, trophic levels, food chains, and food webs. Producers like plants generate their own food through photosynthesis while consumers obtain energy by eating other organisms. Food chains show single pathways of energy transfer and food webs illustrate the complex interconnections between multiple food chains in an ecosystem.
Species interactions
Species interactions can take several forms, including positive associations like mutualism, commensalism, and predation, as well as negative associations like competition. Predation involves one species hunting another for food, while coevolution describes how some species evolve together over time in response to each other. Symbiotic relationships like mutualism benefit both species, commensalism benefits one, and parasitism benefits one at the expense of the other. Competition for limited resources can lead to competitive exclusion of one species or resource partitioning where species divide resources to coexist.
Obj 1&2 compare ways plants and animals use energy and how they are dependant
Plants obtain energy from sunlight through photosynthesis, which builds plant material. Animals obtain energy through respiration, where sugar molecules from food are broken down to release energy. Sunlight provides energy for most living things, with plants using it to make food and herbivores eating plants, while carnivores eat herbivores and are later broken down by bacteria and fungi, completing the energy connection between organisms.

This document discusses different types of interactions between organisms in an ecosystem. It explains that organisms have feeding relationships where some organisms obtain food by eating other organisms. It then defines several key relationship types between organisms, including predator-prey relationships, competition for resources, mutualism, parasitism, and commensalism. Food chains and food webs are also discussed as a way that energy passes between organisms in an ecosystem.
Species Interaction
Species interaction refers to the relationships between different organisms. There are several types of species interactions: competition (-,-), predation (+,-), parasitism (+,-), commensalism (+,0), mutualism (+,+), and amensalism (-,0). Coevolution can occur when two species evolve in response to one another through these interactions over time. Species interactions are important for maintaining natural balances within ecosystems as no species can survive without some degree of interaction with other species.

Describe three different symbiotic relationships, with examples. Which relationship produces the
most coevolution? Explain.
Please type the answer. Type the answer in your own words please. no copying from the internet
has to be in own words
Solution
Three different types of symbiotic relatioships are :
1. Mutualism
2. Commensalism
3. Parasitism
1.Mutualism is the relationship between organisms where both are benefitted from each other.
Examples of mutualism:
a. Oxpecker on zebra eats pest. Oxpecker gets food and zebra gets rid of pest.
b. Shape of flower and structure of pollinator is also an example of mutulism as shape of the
flower is specific for the pollinator to allow pollination.
c. Bacteria in gut of human intestine benefit human by partially digesting the food difficult to
digest. Bacteria gets food through this and human is able to digest tougher to dogest food.
d. Mycorhhiza is association between fungus and gymnosperm root. Plant gets benefitted by
collection of nutrients from soil and fungus gets benefit by plant in form of food and shelter.
2. Commensalism: In commensalism association, one organism is benefitted whereas other is not
affected at all.
examples:
a. Cattle Egret and cattle: as cattle grazes and uproots plants, insects that escape are eaten by
egret. Egret gets the benefit wheras cattle is not affected.
b Sucker fish attaches itself to the shark and travels along. Shark doesnt get affected whereas the
sucker fish gets left over food of shark.
c.Epiphytes are plants that grow on larger trees. They just climb the trees for receiving sunlight
and do not cause any affect to the plant.
d. CLown fish lives in tentacles of Sea anemones. Sea anemone doesnt get affected whereas
clown fish gets the advantage of protection from predators.
3. Parasitism: In this relationship, the parasite harms the host to derive the benefit in terms of
food or shelter or both. In this type of relationship one species is harmed whereas other is
benefitted.
examples of parasitism:
a. Lice on Human body: Lice sucks blood can causes harm to human.
b. Cuscuta causes harm to higher plants by living on it and taking the benefit of food and shelter.
c. Ascaris lives in human intestine . It benefits from receiving food and shelter and causes harm
to human.

nutrients.
Out of these relationships, coevolution is most important for species showing mutualistic
behaviour as:
1. They both have large dependency on each other for their survival.
2. Any change in one species can lead to extinction of the other. Coevolution is the only strategy
for their survival..
Species interaction between organism.
This document discusses different types of species interactions: neutralism, competition, amensalism, symbiotic relationships (commensalism, mutualism, parasitism), and antagonism (predation, herbivory). Neutralism occurs when two species do not affect each other. Competition involves two species requiring the same limited resources. Amensalism harms one species without benefiting the other. Symbiotic relationships benefit at least one organism. Antagonism benefits one species at the expense of another, such as through predation or herbivory.
Positive species interaction
This document discusses different types of positive species interactions, including commensalism, proto-cooperation, and mutualism. Commensalism benefits one species without affecting the other, such as barnacles attaching to whales. Proto-cooperation benefits both species but is not obligatory, like oxpeckers eating parasites off impalas. Mutualism strongly benefits both participating species and they have evolved to depend on each other, such as lichen forming from algae and fungi symbiosis or cellulose-digesting bacteria in herbivore guts.
M.r.tripathi (biology xii populaiton interction)
The document describes different types of interspecific interactions:
1. Mutualism benefits both species, like the relationship between fungi and plants in mycorrhizae.
2. Predation benefits the predator species while harming the prey species, such as insects flushed out by cattle being eaten by egrets.
3. Parasitism benefits the parasite while harming the host, for example tapeworms living inside the intestines of another organism.
4. Commensalism benefits one species without affecting the other, like orchids growing on trees.
5. Competition harms both species as they contend for the same limited resources, as seen with flamingoes and fish competing for z
Community ecology
A community is a group of interacting species that live in the same area. There are two hypotheses about communities: the individualistic hypothesis views a community as species with similar environmental needs occurring together by chance, while the interactive hypothesis views a community as closely linked species dependent on biotic interactions. Major interspecific interactions include predation/parasitism, competition, commensalism, and mutualism. Species have various defenses against herbivores and predators, and ecological niches define an organism's role in its environment. Succession over time replaces communities as environments change.
Review question chap5
This document contains a student's responses to review questions about chapter 5. It lists examples of predator-prey relationships including a snake and chicken, penguin and fish, lion and zebra, frogs and insects, and an eagle and mouse. It defines the difference between an ecosystem and a community, with an ecosystem including both the living community and abiotic environment. Humans raising cattle for food is described as a form of predation but also potentially a mutualistic relationship. Examples are given of organisms that are herbivores, carnivores, and omnivores. The different trophic levels in an ecosystem are outlined as producers, primary consumers, secondary consumers, carnivores that eat carnivores, and

major interactions among organisms in a food web
Food chains or food webs : they depict the eating connections amongst species and speak to the
stream of vitality through a biological community.The Sun gives vitality to producers , like ,
plants. Producers change over this energy into a shape that can be devoured by creatures.
Creatures that eat producers are then devoured by creatures at higher trophic levels. In the long
run all living beings are crushed spirit down into supplements by decomposers. Makers utilize
these supplements to change over sunlight based vitality into a usable frame and the natural way
of life proceeds. Evolved ways of life and nourishment networks portray connections between
life forms at various trophic levels.
Symbiosis: It is a collaboration between people of various organic species. No less than one of
the life forms gets an advantage from the collaboration. The other living being can either get an
advantage, be hurt, or not be influenced at all.
Commensalism : it includes a cozy relationship between the two life forms included. There are
three primary sorts of advantageous connections: commensalism, mutualism, and parasitism.
Commensalism : it is a sort of cooperative relationship where one of the life forms gets an
advantage and the other is not altogether hurt or aided by the connection. Frequently the life
form that is getting an advantage can either discover sustenance all the more effortlessly in view
of the association or is ensured by the other living being.
For instance, cows egrets eat creepy crawlies in fields and fields. Substantial nibbling herbivores,
for example, dairy cattle and stallions, mix up creepy crawlies as they munch on grass in fields.
Cows egrets regularly take after behind the munching herbivores and gobble the creepy crawlies
that are mixed up. The steers egret is getting the advantage of having the capacity to discover
nourishment effortlessly. The touching herbivores are not influenced by the nearness of the
egrets. This is a case of commensalism.
Mutualism: it is a sort of harmonious relationship in which both life forms included get an
advantage. Blossoms and their pollinators are a standout amongst the most widely recognized
types of mutualism. Plants can\'t repeat without being pollinated. Numerous sorts of plants rely
on upon creepy crawlies, for example, moths, honey bees, wasps, and scarabs, to perform
fertilization. Plants that depend on pollinators pull in the pollinator by the shape, shading, or
possess an aroma similar to their blossoms. The pollinator gets nectar or dust as a nourishment
source from the blossom. As the pollinator gets the sustenance, it gets dust on its legs and body
that can be spread to another plant. When it visits a moment plant of similar species, the dust
from the principal plant is exchanged to the regenerative organs of the second plant and
fertilization can happen. Both crea.
Community Interactions And Sucession
Community interactions in an ecosystem include competition, predation, and symbiosis. Competition occurs when organisms attempt to use the same limited resource. Predation is when one organism captures and feeds on another. Symbiosis describes close relationships between species, including mutualism, commensalism, and parasitism. Ecological succession describes how communities change over time in response to disturbances through predictable stages as new species move in and old species die out. Human activities like land clearing can decrease species diversity.

Weathering and erosion shape the Earth's surface over time. Weathering is the breakdown of rocks into smaller pieces through physical, biological, and chemical processes. Physical weathering breaks rocks through forces like earthquakes, while biological weathering occurs as plants and microbes grow and dissolve minerals. Chemical weathering changes the properties of rocks through exposure to acids. Erosion is the movement of weathered rocks and soil by forces like water, wind, and ice. Both weathering and erosion continuously alter the landscape through natural cycles.

White light is made up of the colors of the visible spectrum. When white light hits water droplets in the air, it is refracted and separated into different colors to form a rainbow. The water droplets act as prisms to refract the light. Rainbows occur when sunlight passes through water droplets in the air. Different materials can transmit light directly, scatter light as it passes through, or allow some light to pass through blurred.

Personal hygiene and proper handwashing are important for food safety. Germs can easily spread and cause foodborne illness if sick workers handle food. Good hygiene habits include washing hands thoroughly with soap and water for 20 seconds after using the bathroom, touching your face, handling raw meat or garbage, sneezing or coughing. Workers should also keep nails trimmed, use hair restraints, wear proper clothing, cover cuts and stay home if sick to prevent contamination and spreading germs in food preparation areas.

Roots absorb water and minerals from the soil and anchor the plant. There are three main root systems: taproots have a large main root with smaller roots, fibrous roots have a network of slender roots without a main root, and aerial roots grow from above-ground plant parts to provide additional support. Stems transport water and minerals between the roots and other plant parts like leaves, flowers, and fruit. Stems can be aerial, above ground, or subterranean, below ground. Leaves are made of a petiole, blade, veins and produce food for the plant through photosynthesis. There are simple leaves with one blade and compound leaves with multiple leaflets.

Heat and electricity are forms of energy that can be transferred through conductors. Good conductors of heat and electricity, like metals, allow for the easy movement of atoms and electrons. Poor conductors, or insulators, tightly bind their electrons and do not readily transmit heat or electricity. Common good conductors include silver, copper, aluminum, and gold, while materials like cork, paper, fabric, rubber, ceramics, leather, and wood are typically good insulators.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

- 1. Harmful Interactions in an Ecosystem Ms. Rene C. Miking
- 2. Negative Interactions in an Ecosystem 1. Amensalism- is the relationship between two organisms, where one is hurt.
- 4. 2. Parasitism - one organism called parasite benefits from the interaction while harming the other organism called host. - Ex: - Aphids (tiny insects) on the leaves of plants - Tapeworms and hookworms inside the body of animal or human
- 5. 3. Predation - interaction where the predator, the bigger or stronger organism, kills the prey, the smaller or weaker animal, for food. - Ex: - Hawk and snake - Zebra and lion
- 6. 4. Competition - species contends with members of its own species for resources. - Ex: In crowd areas, plants of the same species compete with one another for space, nutrients, and materials needed for photosynthesis such as water and sunlight. Plants that lose out grow short and weal and eventually die. - Ex: animals compete to obtain food such as chickens the faster and stronger will be able to pick up more grains, while the slower ones will get lesser grains or none at all.
