Ecology
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. There are three main types of feeding relationships: producer-consumer, predator-prey, and parasite-host. Producers, like plants, make their own food through photosynthesis. Consumers eat other organisms for energy and include both predators that hunt prey and animals that eat plants or other animals. A food chain shows what organisms eat in a linear feeding order starting with producers, while a food web depicts the complex and interconnected feeding relationships in an ecosystem.
Food chain
Predators eat prey in any habitat, with predators being organisms that hunt prey, which are organisms that are eaten. Food chains show the flow of energy from one organism to another, always starting with a plant and continuing as each organism is consumed up the chain, with some animals like birds at the top of the food chain as they are not hunted by other animals.
Food relationships among living organisms
1) Food is the main source of energy for living organisms. Green plants produce their own food through photosynthesis while animals depend directly or indirectly on plants.
2) There are three main types of food relationships: predation, symbiosis, and saprophytism. Predation involves one organism attacking, killing, and devouring another for food.
3) Predation is common in the animal world with examples like lions preying on deer. Some plants also prey on insects. Organisms use defenses like camouflage and mimicry to protect themselves from predators by blending in with their environments.
The earth kingdom
The document discusses the five kingdoms of nature: Animalia, Plantae, Fungi, Monera, and Protista. It provides brief descriptions of each kingdom. Animalia includes mammals, fish, reptiles, amphibians, and insects. Plantae have organs like leaves, roots, and stems to support themselves and reproduce. Fungi include mushrooms and molds and obtain nutrients by decomposing plants. Monera contains unicellular bacteria. Protista includes slime molds and algae. The five kingdoms classification system was developed by biologist Lynn Margulis to categorize life on Earth.
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.
Science 9 Unit A Biological Diversity Section1.2 Lesson Interdependence
1) The document discusses biological diversity and interdependence between species within an ecosystem. It defines key terms like niche and different types of symbiotic relationships between species like mutualism, commensalism, and parasitism.
2) Species can coexist in the same habitat through resource partitioning, where they divide resources like occupying different areas of the same tree or feeding on different parts of the tree.
3) Variation within species enables closely related organisms to survive in the same ecosystem by occupying different niches.
Chapter 4 interaction between organism
This document discusses different types of interactions between living organisms: prey-predator relationships, competition, and symbiotic relationships including commensalism, mutualism, and parasitism. It provides examples for each type of interaction: prey-predator examples include owls and rats; competition examples include competing for food or light; commensalism examples include remora fish and sharks; mutualism examples include lichen and nitrogen-fixing bacteria and plants; and parasitism examples include tapeworms and humans. The document also notes the effects of each interaction type on the organisms involved and discusses biological control as an alternative to pesticides in agriculture.
Food chains and webs presentation
This document defines key ecological terms and concepts including:
- Autotrophs are organisms like plants that can produce their own food through photosynthesis. They are also called producers.
- Heterotrophs or consumers cannot produce their own food and rely on other organisms for sustenance. There are herbivores, carnivores, omnivores, and decomposers.
- Food webs and food chains describe the transfer of energy as organisms consume each other across trophic levels from producers to various consumers to decomposers.

Ecology: Symbiotic Relationships
This document discusses different types of symbiotic relationships between species: predation, parasitism, competition, mutualism, and commensalism. It provides examples for each type, such as predators and prey, parasites like ticks, competing species like Darwin's finches, mutualistic relationships like plants and pollinators, and commensal relationships like whales and barnacles. The document explains how these relationships can influence species' adaptations through mimicry, defenses, niche partitioning, and character displacement.
U07 The simplest living things
The document discusses the characteristics of the simplest living things, including bacteria, archaea, protozoa, algae, protists, and viruses. It describes their cell structures, modes of nutrition, reproduction, habitats, impacts on health, and importance in ecosystems. Examples like bacteria classification and the viral infection process are explained.
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

This document discusses four types of negative interactions in an ecosystem: 1) Amensalism, where one organism is harmed by the other. 2) Parasitism, where one organism (the parasite) benefits while harming its host. 3) Predation, where a predator kills prey for food. 4) Competition, where members of the same species compete for limited resources like space, food, and nutrients. Examples are given for each type of interaction.
ANIMAL RELATIONSHIPS Powerpoint presentation by gayathri.a.t
This document discusses the different types of relationships found among organisms. There are two main types of interactions - positive interactions which benefit one or both organisms, and negative interactions which harm one or both organisms. Positive interactions include mutualism, where both organisms benefit each other, and commensalism where one benefits while the other is not harmed. Negative interactions include predation, where one organism is harmed as the other's prey, parasitism where one benefits while harming its host, and competition for resources which can harm individuals. These relationships are an important part of ecosystems, with energy flowing through food chains and webs formed by animal interactions.

The Physics Quest competition ended on Monday, with Mrs. McCarthy collecting the final answers from each class to submit. The document discusses animal classification terms like vertebrate and invertebrate. It provides an overview of section 1 which covers animal survival behaviors such as predation, innate and learned behaviors, hibernation, and circadian rhythms. Camouflage and warning coloration are described as animal adaptations for protection.
.Agus report
This document provides information about animals, trees, buildings, and natural phenomena. It defines animals as organisms classified as animalia or metazoans. It describes vertebrates and invertebrates and provides examples of each. It defines trees as having woody stems and branches that grow upright. It describes buildings as structures for housing or infrastructure constructed using materials like stone, wood, brick, cement, and metals. It defines natural phenomena as non-artificial events in physics like volcanic eruptions, weather, and decay.
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.
Levels of Classification Pedagogical Plan
This pedagogical plan outlines a science lesson for 8th grade students on biodiversity. The lesson will take place over one week and focus on species diversity, the hierarchical taxonomic system for classifying species, and protecting endangered and economically important species. Students will learn to classify organisms using the taxonomic system and describe how high biodiversity maintains ecosystem stability. Assessment tasks include a summative test with questions on classifying sample organisms and a performance assessment where students create a proposal to classify organisms in a way that promotes species survival. Learning activities involve classifying different organisms, interpreting taxonomic diagrams, and discussing levels of classification.
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.
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 in an ecosystem: mutualism, comensalism and parasitism.
This document describes different types of relationships between individuals. Within a species, there are gregarious associations (unorganized groups), families (small related groups), and societies (organized groups with distributed work). Between species there are mutualism (benefits both), parasitism (benefits one at the expense of the other), and commensalism (benefits one without affecting the other). Examples include birds eating ticks off mammals (mutualism), fleas living on mammals (parasitism), and orchids growing on trees (commensalism).
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.
Biology 15.3
The document outlines Darwin's theory of evolution by natural selection, including key concepts such as artificial selection, the struggle for existence, fitness, adaptation, survival of the fittest, natural selection, descent with modification, common descent, homologous structures, and vestigial organs. Darwin proposed that natural selection acts on natural variations within a population so that individuals with traits better suited to their environment will survive and reproduce more successfully, passing on those favorable traits.
Food chain and webs
The document defines the basic structure and components of a food chain. It explains that a food chain involves producers, primary consumers that eat producers, secondary consumers that eat primary consumers, and sometimes tertiary consumers. Producers are organisms like plants that produce their own food, while consumers eat other organisms and can be herbivores, carnivores, or omnivores. Energy flows through a food chain from producers to various consumer levels in a linear pathway.
Community interactions-and-sucession
Community interactions including competition, predation, and symbiosis powerfully affect ecosystems. Competition occurs when organisms attempt to use the same ecological resource, leading to winners and losers. Predation is when one organism captures and eats another. Symbiosis describes close living relationships between species, including mutualism, commensalism, and parasitism. Ecosystems are dynamic and change over time through ecological succession in response to disturbances. Succession proceeds through predictable stages as early pioneer species establish and later species move in.
Food_web_and_food_chains_period_1.pdf
This document discusses food chains and food webs. A food chain is a sequence of organisms where each uses the next lower member as a food source. Plants are primary producers that create their own food through photosynthesis. Animals are consumers that eat plants or other animals for energy. Herbivores eat plants, carnivores eat animals, omnivores eat plants and animals, and detritivores eat dead materials. A food web is an interlocking pattern of multiple food chains within an ecosystem.
Ecosystems: Food chain
Producers such as trees feed on sunlight and water and provide nutrients to other living things. Consumers include animals that are heterotrophic and eat other organisms to survive. There are three types of consumers: herbivores that eat producers, carnivores that eat other consumers as hunters or scavengers, and omnivores that eat producers, consumers, and sometimes decomposers. Decomposers such as fungi and bacteria decompose remains of other organisms and release nutrients into the soil. A food chain shows the relationships between producers, consumers, and decomposers.
Ppt on living things
1. Producers, consumers, scavengers, and decomposers are the four main categories of living things. Producers like plants can make their own food through photosynthesis, while consumers depend on other organisms for food.
2. Scavengers feed on dead animals, acting as environment cleaners. Decomposers like fungi and bacteria break down dead organisms, recycling nutrients in the soil.
3. Plants, animals, and decomposers are interdependent. Pollinators like bees help plants reproduce, and animals disperse seeds. Decomposers break down waste and make nutrients available to plants.
Ecosystems
This document defines key terms related to ecosystems, including habitat, population, community, and ecosystem. It then describes the components and interactions within forest ecosystems, including:
- Plants are primary producers through photosynthesis
- Herbivores are primary consumers that eat plants
- Carnivores are secondary consumers that eat herbivores
- Tertiary consumers eat other carnivores
- Decomposers like fungi and bacteria break down dead materials and return nutrients to the soil.

Gaurav and webs
This document discusses food chains and food webs within an ecosystem. It explains that producers like plants and algae generate food, while consumers like herbivores, carnivores and omnivores eat the producers or other consumers. Food chains involve a single path where each organism is eaten by the next in line, while food webs are more complex networks of interconnected food chains. Energy flows from producers to primary, secondary and tertiary consumers, and decomposers break down waste.
Ecology
Ecology is the study of interactions between organisms and their environment. The biosphere is the global ecosystem, encompassing all living things found in air, land, and water on Earth. Ecologists study how both biotic factors (living things) and abiotic factors (non-living things) influence organisms and populations within various levels of organization, from individuals to ecosystems. Energy and matter flow through ecosystems via food chains and food webs, with only about 10% of available energy being transferred between trophic levels. Key biogeochemical cycles such as the water, carbon, nitrogen, and phosphorus cycles recycle critical elements and compounds.
fungi.pptx
Fungi are a diverse group of organisms that include mushrooms, molds, yeasts, and microfungi. They obtain nutrients by absorbing them from surrounding materials and are important decomposers in ecosystems. Fungi can reproduce both sexually through structures like basidia and ascocarps, and asexually through spores, budding, or fragmentation. They play key roles as decomposers, pathogens, and mutualists with other organisms like plants and algae in lichens.
PHOTOSYNTHESIS.pptx
Photosynthesis involves three stages: capturing energy from sunlight, making ATP, and building carbohydrates. The goal is to use carbon dioxide and sunlight to produce carbohydrates that store energy.
Plants reproduce sexually through pollination and asexually through runners, buds, and other vegetative structures. Animals also reproduce sexually and asexually through various methods like budding, fragmentation, and regeneration depending on the species.
The evolution of living things over time is evidenced by fossils, homologous and analogous structures, and vestigial structures while factors like environment and extinction events have contributed to changes in organisms.
ECOSYSTEMS
An ecosystem is a system made up of the living and non-living parts of an environment that interact as a unit. It contains individuals of a species, populations of multiple individuals of the same species, and communities of multiple interacting populations. Energy flows through ecosystems via food chains, with producers like plants obtaining energy from the sun, consumers eating producers or other consumers, and decomposers breaking down waste. Food webs illustrate how different food chains interconnect within an ecosystem.
Principles of ecology
Ecology is the scientific study of interactions between organisms and their environment. The components of ecology include abiotic (non-living) factors like temperature and biotic (living) factors like other organisms. A niche describes an organism's role and interactions within its ecosystem, including how it meets its needs. Relationships between organisms in an ecosystem can be symbiotic like mutualism, or involve one organism benefiting more than the other like parasitism or commensalism. Natural selection leads to evolution as organisms with traits better suited to their environment are more likely to survive and pass on those traits, changing the gene frequency in a population over time. Speciation occurs when reproductive isolation splits one species into two distinct species.

This document provides an overview of key concepts in ecology, including definitions of important terms like habitat, adaptation, camouflage, mimicry, producers and consumers. It also describes ecological concepts such as food chains, food webs, and energy flow between organisms. Sampling techniques for organisms are introduced, like quadrat sampling and pitfall traps. Population dynamics are covered, like population curves, factors affecting population size, and population pyramids. Cycles of important elements like carbon and nitrogen are also summarized.
Understanding Symbiosis
This document discusses symbiosis, which is defined as two organisms living together where at least one benefits. There are three main types of symbiotic relationships: mutualism, where both organisms benefit; commensalism, where one benefits and the other is unaffected; and parasitism, where one benefits and the other is harmed. Several examples of each type of relationship are provided, such as bees and flowers in mutualism, whale and barnacle in commensalism, and fleas and dogs in parasitism.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
