Components of the Ecosystem and Ecological Relationships
The two components of an ecosystem are biotic (living) and abiotic (non-living) factors. Biotic factors include plants, animals, fungi, protists and bacteria. Abiotic factors include minerals, sunlight, air, climate and soil. An ecosystem is a community of living organisms interacting with each other and their non-living environment. Biotic factors such as plants and animals have different ecological roles as producers, consumers, and decomposers. Interactions within species are intraspecific, while those between species are interspecific.
pre-AP Bio Chapter 3 part 1
Ecology is the scientific study of interactions between organisms and their environment. It examines how biotic factors like other living things and abiotic non-living factors influence ecosystems. Ecologists use observation, experimentation, and modeling to study organisms, populations, communities, ecosystems, biomes, and the biosphere.

Biotic factors refer to the living organisms in an ecosystem, including animals, plants, fungi, protists, and bacteria. The document explains that ecosystems are complex systems where abiotic and biotic factors interact and depend on one another, so damage to one part can have disastrous effects on the other parts.
2.1 Interactions Ecosystem Notes Ch5 L1
The document defines key terms related to ecosystems, including ecosystem, abiotic and biotic factors, population, community, ecology, habitat, and niche. It explains that an ecosystem includes all living and non-living things in an area. Abiotic factors are non-living parts like water, soil, climate and sunlight that living things need to survive, while biotic factors are the living parts like plants, animals, fungi, protists and bacteria that all have important roles in the ecosystem.
Elements of an ecosystem
The document discusses the elements of ecosystems in three types of forests: Mediterranean forests, Atlantic forests, and forests of the Canary Islands. It examines the biotope, biocenosis, and interactions for each forest ecosystem. It also provides information on the ecosphere and biosphere, defining the ecosphere as the area around a star suitable for life and noting Earth and Mars comprise our solar system's ecosphere, and the biosphere as all living things on Earth inhabiting the troposphere, hydrosphere, and upper geosphere.
Abiotic and biotic factors
Abiotic factors refer to non-living environmental conditions such as sunlight, temperature, rainfall, and soil composition. Biotic factors refer to living organisms such as plants, animals, and other organisms that inhabit an environment.

Unit 14a Relationships, biotic, and abiotic factors
Ecology is the study of interactions between living things and their environment across different levels of organization. These levels from largest to smallest are biome, ecosystem, community, population, and organism. Ecologists use observation, experimentation, and modeling to understand these interactions. Field experiments provide a more accurate picture of natural interactions but make it difficult to determine cause and effect.
Abiotic or Biotic factors
Ecosystems consist of interacting biotic and abiotic factors. Organisms rely on abiotic factors like temperature, water, and soil composition as well as biotic factors such as food sources and other species. Competition occurs when multiple individuals or populations rely on limited resources within the same niche. A limiting factor is any biotic or abiotic resource that, if depleted, prevents an organism or population from growing.
Ecosystem
An ecosystem is defined as the interaction between living and non-living components in a given area. It includes all living organisms such as plants, animals, and bacteria, as well as non-living factors like water, soil, climate, and weather. The structure of an ecosystem describes its organisms and physical features, and is made up of abiotic factors such as soil, water, and minerals, as well as biotic factors like plants, animals, and fungi. Some examples of ecosystems include deserts, forests, hills, ponds, and aquatic environments.
Grade9, U3-L5 biotic and abiotic factors
This document discusses biotic and abiotic factors that influence ecosystems and populations. Abiotic factors like temperature, light, water, and soil determine where species can survive based on their tolerance ranges. Within tolerance ranges, optimal conditions allow populations to flourish while stress near limits can reduce health. Biotic factors like competition, predation, and mutualism also influence species success. As populations increase in size, resource demands increase until the ecosystem reaches its carrying capacity, or maximum sustainable population.
Abiotic components
Biotic components are living things like plants, animals, and humans that shape ecosystems. They need energy and food - plants produce food through photosynthesis, animals and humans consume other organisms or their byproducts, and decomposers like bacteria and fungi break down dead matter. Abiotic components are non-living environmental factors such as sunlight, soil, water, and air that affect ecosystems. Both biotic and abiotic factors work interdependently to provide a functioning environment for organisms in an ecosystem.

An ecosystem consists of all the living and nonliving components in an environment and the interactions between them. It includes biotic factors like producers, consumers, and decomposers as well as abiotic factors such as water, sunlight, and temperature. Producers like plants obtain energy through photosynthesis while consumers obtain energy by consuming other organisms. Decomposers play an important role by breaking down dead organic matter and recycling nutrients.
Ecosystem
This document defines an ecosystem and its components. An ecosystem is a community of living organisms that interact with non-living elements in their environment. It has biotic components, which are the living organisms, and abiotic components, which are non-living elements like climate, soil, water and nutrients. The biotic components are classified into producers, consumers and decomposers based on how they obtain food. Producers like plants produce their own food through photosynthesis. Consumers eat other organisms for food and are divided into primary, secondary and tertiary consumers. Decomposers break down dead organisms and release nutrients. Ecological succession is the process where one community replaces another over time until a stable community develops in

I've basically discussed about the concepts and types of ecosystem in this presentation. I've also discussed about ecosystem succession in the end.
Factors that shape Ecosystems
Factors that shape an environment. Abiotic and Biotic, organisms niche, interactions between species in communities, succession (primary and secondary).
Succession
Ecological succession is a series of predictable changes that occur in a community over time, typically resulting in an increase in species diversity. Succession can be primary, occurring in areas with no previous community traces like new lava, or secondary, in partially disturbed areas where soil survives. Pioneer species alter the environment making it suitable for other species in successional stages from grasses to shade-tolerant trees in a climax community.

An ecosystem includes all biotic factors such as plants, animals and microbes as well as abiotic factors like air, water and soil. Biotic factors interact with each other and abiotic factors in complex ways. The document also discusses biomes as large regional communities defined by climate and plant life, and provides examples of biomes and ecosystems.
Notes symbiosis
Symbiosis is a close association between two different species. There are three types of symbiotic relationships: commensalism, where one species benefits while the other is not affected; mutualism, where both species benefit from the relationship; and parasitism, where one species benefits while harming the other. Examples provided include epiphytic plants in commensalism with trees, mycorrhizal fungi in a mutualistic relationship with plant roots, and tapeworms as parasites that live in animal digestive tracts and steal nutrients. The document concludes with a homework assignment to research and write about one example of mutualism and parasitism.
Trophic levels
Primary producers use energy from the sun or chemicals to produce organic molecules. Consumers rely on other organisms for energy and nutrients. There are different types of consumers including herbivores, carnivores, omnivores, scavengers, decomposers, and detritivores. Food chains show the transfer of energy between organisms through eating, while food webs show complex feeding relationships in an ecosystem. Trophic levels refer to the steps in a food chain, with primary producers at the base and increasing consumer levels above. Only about 10% of available energy is transferred between trophic levels.
Levels of biological organization
The document provides instructions for constructing interactive notes for an ecology unit. It tells the student to label the cover with their name and the unit topic. It then instructs them to staple paper to the cover and number the pages. The next pages will define and provide examples for 5 levels of biological organization - organism, population, community, ecosystem, and biosphere. The student is then asked to find or draw pictures illustrating each level and label them accordingly.
Competition
The document defines niche as the range of conditions a species lives in and how it obtains resources to survive and reproduce. A niche explains how a species fits into an ecosystem. Habitat is a species' location while niche includes location and occupation. The document also defines competition as occurring when organisms seek the same limited resources in the same place and time, and can be intraspecific or interspecific. The competitive exclusion principle states that no two species can occupy the exact same niche, while niche partitioning allows species to divide resources and coexist by each occupying a different niche.
Diversity
The document defines species richness, species evenness, and species diversity. It notes that species diversity incorporates both richness and evenness. It also discusses biodiversity as the total genetic variation among organisms and some reasons for preserving biodiversity, including potential new medicines from plants, pest resistance genes in crop wild relatives, and ecosystem services from diverse ecosystems. Finally, it introduces keystone species as those that play a key role in maintaining ecosystem diversity and structure, providing sea otters and their effect on kelp forests as an example.
Components of ecosystem
The document summarizes the key components of an ecosystem. It describes abiotic components as non-living physical and chemical factors like air, water, soil, and basic elements. Biotic components are the living parts, including populations of animals, plants, and microbes. It outlines the relationships between these groups, with autotrophs (producers) converting inorganic materials to organic materials through photosynthesis, heterotrophs (consumers) feeding on autotrophs or other organisms, and saprotrophs (decomposers) breaking down dead organic matter and recycling nutrients.
Ecology
This document provides an overview of key concepts in ecology. It discusses producers and consumers, trophic levels, ecological pyramids, and ecological interactions between organisms such as competition, predation, and symbiotic relationships. Producers, like plants, use photosynthesis or chemosynthesis to produce energy from sunlight or chemicals. Consumers rely on producers and other organisms for food and include herbivores, carnivores, and omnivores. Energy and biomass decrease at higher trophic levels in ecological pyramids. Organisms interact through competition for resources, predation of prey, and symbiotic relationships like mutualism, commensalism, and parasitism.
Habitat and niche
The document discusses habitat and niche. It defines habitat as the place where a population lives, obtains resources, and reproduces. Niche is defined as the set of interactions a population has within its community, including its role as a predator, prey, or through commensal/mutualistic relationships. A population's niche may also include its habitat, activity periods, and no two populations can occupy the same niche.
05 ecological niches and cycles
1) The document describes ecological niches and the nitrogen and carbon cycles.
2) An ecological niche includes what a species feeds on, what feeds on it, and how it behaves in its habitat. The niche of black bears is given as an example.
3) The nitrogen and carbon cycles describe how nitrogen and carbon move between the atmosphere, living things, and the lithosphere through natural processes like photosynthesis, cellular respiration, nitrogen fixation, and weathering.
Energy and the ecosystem IGCSE
Energy flows through ecosystems via food chains and webs. Producers, like plants, capture energy from the sun and convert it to chemical energy during photosynthesis. Consumers obtain energy by eating other organisms and are classified as herbivores, carnivores, or omnivores based on their diets. Energy and nutrients transfer between trophic levels with about 10% traveling to the next level, resulting in pyramids of numbers and biomass that narrow with each increasing trophic level. Key nutrients like carbon and nitrogen cycle through abiotic and biotic factors, being used and reused by different organisms in ecosystems.
Habitat and niche report
This document discusses habitat and niche. It defines habitat as the natural environment where an organism lives, including physical factors like temperature and moisture as well as biotic factors like availability of food and predators. A microhabitat refers to small-scale habitat requirements. Examples of animal and plant habitats are provided for different regions. Niche is defined as an organism's role in an ecosystem, including what it eats, where it lives, and what it does. The fundamental niche is the full range of conditions an organism can survive in, while the realized niche is the actual conditions it is found in due to interactions. Examples of beaver, raccoon, and red-tailed hawk/barred owl niches are described to illustrate these concepts
Abiotic And Biotic Interaction
The document discusses abiotic and biotic factors in the Rocky River nature reserve in Northeast Ohio. It notes that the area was under water 360 million years ago, and that the shale cliffs were formed from rich muds deposited by streams from the Appalachians. One notable fossil found is the "Terrible" fish Dunkleosteus, which grew up to 20 feet long. Several photos show different abiotic factors like soil horizons, fallen trees, mushrooms, fog, waves, and erosion. Biotic factors include food webs involving detritivores, grazers, and predators like the red-tailed hawk. The assignment covered the long history and evolution of biodiversity in the
Ecological niche 811
This document summarizes the concept of ecological niche. It discusses niche as a species' habitat requirements, its functional role in an ecosystem, and its position within a local community. Key concepts covered include the fundamental niche representing all conditions a species can persist in, versus the realized niche reflecting interactions with other species; competitive exclusion and limiting similarity regarding how similar niches can be for coexistence; and modes of coexistence such as niche differentiation and dominance hierarchies.
Niches
This document discusses ecological niches and niche theory. It begins by defining the concepts of fundamental and realized niches, and the principle of competitive exclusion. It then discusses how species can reduce niche overlap through habitat segregation, niche compression into competitive refuges, and character displacement. Examples of niche partitioning in various systems like barnacles, sedges, and sticklebacks are provided. The document also addresses topics like niche crossovers, adaptive radiation, vacant niches, and challenges to classical niche theory from neutral models of biodiversity.
Ecological niche
1) An ecological niche refers to how a species interacts with other species and its physical environment to obtain resources like food and shelter.
2) The principle of competitive exclusion states that two species cannot coexist indefinitely if they utilize the same limiting resources in the same habitat.
3) Species can reduce niche overlap through mechanisms like habitat segregation along dimensions like feeding height, behavior, and nesting times to avoid direct competition.
Chapter 21 Ecology Lesson 1 - Biotic and abiotic factors
(a) Energy flows in one direction through ecosystems from producers to consumers in food chains, rather than cycling. (b) Producers are organisms that produce their own food, consumers eat other organisms, and trophic levels refer to positions in a food chain. (c) Energy is lost at each trophic level as it is transferred between organisms, so the amount of energy decreases higher in the food chain.
The components of an ecosystem
The structural components of an ecosystem consist of nonliving arena and the living organisms.

What is ecology
Ecology is defined as the scientific study of interactions among organisms and between organisms and their physical environment. Ecologists study different levels of organization, from organisms to populations, communities, ecosystems, and biomes. Both biotic factors like other organisms and abiotic factors like temperature influence organisms and shape environments through complex interactions.

Environment is defined as the combination of physical and biological factors surrounding and affecting an organism. It includes biotic factors such as plants and animals as well as abiotic factors including temperature, light, soil components, and other non-living chemical and physical aspects that can impact organisms and ecosystems. The interactions between biotic and abiotic elements form ecosystems and influence evolution. Key abiotic components of the environment include components of the hydrosphere like oceans, lakes, and atmosphere as well as factors derived from the non-living world.

Components of environment
Importance of healthy environment
Environment:
The surroundings or conditions in which a person, animal, or plant lives or operates.
Components of environment:
Everything in our immediate surrounds, including both living and nonliving things like soil, water, creatures, and plants that adapt to their conditions, is referred to as the “environment.”
It is a gift from nature that helps to sustain life on Earth.
The survival of life on Earth depends on the environment.
A biosphere component that affects the condition of the entire planet is an ecosystem.
It includes both live and non living objects in the environment.
The elements that make up the environment can be broadly separated into two groups:
Biotic Components: The biotic or biological component of environment consists of all living organisms. Animals, plants, and microorganisms interact with abiotic elements to build ecosystems.
Abiotic Components: the Non living things like Water, Light, Temperature, Humidity and Soil.
Importance of healthy environment:
As our activities affect the environment in a way, they also affect our life, health, families and communities.
Human civilization has always formed a close bond with their environment. Sitting in fresh air and greenery can increase mental peace, reduce blood pressure, increase attention span.
Healthy environments are essential with human safety and emotional well-being.
Healthy environment reduces the risk of diseases
Enhances quality and length of life
Healthy environment helps to protect the creatures and plants around us.
It Limits global warming

It also covers topics like environmental degradation, sustainable development, the multidisciplinary nature of environmental studies, and the roles of environmental education and engineering.
Abiotic and Biotic Components of Ecosystem by Ashish Verma.pptx
This document summarizes the abiotic and biotic components of an ecosystem. Abiotic components are the non-living physical and chemical factors such as light, temperature, water, and nutrients. Biotic components are the living organisms, including producers like plants that generate energy, consumers that feed on producers or each other, and decomposers that break down dead organic matter. Producers and consumers can be further divided into primary, secondary, and tertiary levels based on the number of trophic levels in the food chain. Abiotic and biotic components interact with and depend on each other to form functioning ecosystems.
Ecological Niche details ..
This document discusses ecological niches and the relationships between organisms and their environments. It defines key terms like ecology, biotic and abiotic factors, and ecological niche. An ecological niche refers to an organism's role and position in its environment, including what it eats, habitat requirements, and tolerance of environmental conditions. The document contrasts fundamental and realized niches, and explains Hutchinson's niche concept and Gause's competitive exclusion principle. Examples are provided of how different species occupy different niches to avoid competition, such as various finch species on the Galapagos Islands. Habitat is defined as the actual environment an organism lives in, while niche refers more to the specific requirements that allow it to survive and reproduce.
Difference between biotic or abotic factors
This document provides an overview of ecosystems and their components. It discusses biotic factors such as producers, consumers, and decomposers. Producers include photoautotrophs and chemoautotrophs that generate energy through photosynthesis or chemical reactions. Consumers are divided into herbivores, carnivores, and omnivores. Decomposers break down organic matter from dead producers and consumers. Abiotic factors that influence ecosystems such as water, sunlight, temperature, soil, and atmosphere are also examined in detail.
Biotic and biotic factor of environment
This document provides an overview of ecosystems and their components. It defines an ecosystem as consisting of both biotic and abiotic factors that interact. The abiotic factors include non-living elements like water, sunlight, temperature, soil, and wind. Biotic factors refer to living organisms and are divided into producers, consumers, and decomposers. Producers include photoautotrophs and chemoautotrophs that generate energy through photosynthesis or chemical reactions. Consumers feed on producers and each other, and decomposers break down organic wastes. Together these biotic and abiotic components maintain stability in the ecosystem.

Notes speciation
This document discusses speciation and the different types. It defines a species as a group that can interbreed and defines speciation as the origin of new species. It describes two main types of speciation: allopatric speciation which occurs when a population is separated geographically, and sympatric speciation which occurs without barriers. Sympatric speciation can happen through habitat isolation, behavioral isolation, temporal isolation, or polyploidy. The document concludes with an activity where students will act out one of the speciation types.
Evolution of complex traits
The document discusses complex traits that have multiple interacting parts, such as eyes and blood clotting. It notes that opponents argue some traits are too complex to have evolved through small changes, but biologists have shown this is not true. Complex traits can evolve through natural selection accumulating small beneficial changes over time, and traits may have had different functions in the past and evolved to take on new roles.
Brain notes projects
The document describes the main structures and regions of the brain. It states that the cerebrum is the largest portion of the brain and consists of two hemispheres connected by the corpus callosum. The cerebrum's surface is wrinkled with gyri and sulci. It then lists the four main lobes of the cerebrum - frontal, parietal, occipital and temporal - and their functions. The limbic lobe which controls involuntary behavior is also mentioned. The cerebellum at the back controls balance and coordination. The diencephalon and brain stem located under the cerebrum are involved in unconscious behaviors.
Vision projects
The document describes the main structures of the eye. It lists the cornea, iris, retina, lens, anterior cavity, vitreous chamber, rods, and cones as key parts. It notes that the cornea lets light in, the iris controls the pupil size, the retina contains photoreceptors, and the lens focuses light onto the retina. It also explains that rods support peripheral and night vision while cones allow for color vision.
Notes genetic drift
This document discusses genetic drift, which is changes in allele frequencies in a population due to chance events rather than natural selection. Genetic drift is more likely to have large effects in small populations and can cause increases in neutral, beneficial, or detrimental traits randomly. Two types of genetic drift are founder effects, which occur when a new population is founded by a small number of colonists, and population bottlenecks, when a population is drastically reduced in size, such as by a natural disaster. Examples are provided of each type.
Diversity of life
The document describes the three domains of life: Archaea, Bacteria, and Eukarya. Archaea are single-celled and prokaryotic. Bacteria are also single-celled and prokaryotic, and can be photosynthetic or heterotrophic. Eukarya have complex cells with nuclei and organelles, and can be single-celled or multicellular, including animals, plants, fungi and protists. It includes a diagram of the tree of life showing the relationships between these domains and kingdoms. Students will research and present on specific types of protists.
Dichotomous keys
Dichotomous keys are tools used to identify unknown items. They work by presenting two choices at each step, narrowing down the options until the item is identified. An example key is provided that uses three steps to distinguish between a ladybug, grasshopper, dragonfly, and housefly based on characteristics like wing coverage and wing position. The document concludes by constructing a sample key to identify strawberries, apples, oranges, and bananas based on color and shape traits.
Science overview
Science is a method of understanding the natural world through making observations and developing testable explanations known as hypotheses. Scientists form hypotheses and models to make predictions that can be observed, and theories are explanations that have been well tested to unify broad observations. The scientific process involves observations, developing hypotheses and models, making predictions, and building theories through testing to best explain natural phenomena.
Photosyn and respiration
The document provides instructions for creating an interactive notebook covering photosynthesis and cellular respiration. It directs the student to construct a 5-page binder cover labeled with the unit topic and their name and period. Definitions are then provided for photosynthesis, cellular respiration, autotrophs, heterotrophs, and adenosine triphosphate (ATP). Photosynthesis and cellular respiration are described as the processes by which plants convert carbon dioxide into glucose and cells break down glucose to produce energy. Autotrophs and heterotrophs are defined in relation to their ability to produce or consume food, and ATP is described as the molecule cells use to store and release energy.
Pcr
PCR is a technique used to make millions of copies of a particular region of DNA. It stands for Polymerase Chain Reaction and is used to amplify a specific segment of DNA. The process involves repeated cycles of heating and cooling of the DNA sample to enable polymerase enzymes to make new copies of the targeted DNA region.
Characteristics of life2012
All living things share universal traits such as having DNA, growing and developing over their lifetime, responding to their environment, reproducing offspring sexually or asexually, maintaining homeostasis, obtaining and using energy through metabolism, evolving over time from common ancestors, and being made of one or more cells.
Graphing in biology
The document describes the characteristics of a good graph, including using a ruler, giving the graph a title, labeling the axes and including units, numbering the axes such that the graph takes up half the page and numbers increase in consistent intervals, and drawing a best fit line rather than connecting data points. It then provides an example of a bad graph that lacks clear labels and spacing and wastes space, and notes issues one could find with it.
Experimental design
Scientists design controlled experiments to test hypotheses and answer testable questions about the natural world. They identify an independent variable to manipulate and keep all other variables constant. For example, an experiment could test if fertilizer increases plant growth by applying fertilizer to half the plots and controlling variables like soil type, water, and sunlight. Good experiments are replicated multiple times to improve reliability. Observations can be quantitative by including numbers or qualitative with descriptions. The results are analyzed to determine if the independent variable affected the outcome.
