Food Chains & Webs
The document discusses food chains and trophic levels within ecosystems. It defines producers as autotrophs that create their own food through photosynthesis, such as grass. Primary consumers or herbivores, such as rabbits, eat the producers. Secondary consumers or carnivores, like hawks, consume the primary consumers. Decomposers such as bacteria break down dead organisms and cycle nutrients in the ecosystem. Most food chains interact forming complex food webs.
Food webs & food chain
The document discusses food webs and food chains. It defines them as models that show feeding relationships between organisms in an ecosystem. A food web consists of multiple interconnected food chains, with producers like plants obtaining energy from the sun and consumers obtaining energy by eating other organisms. The document provides examples of herbivores, carnivores, and omnivores, and explains how energy passes from producers to different levels of consumers in a food chain.

Food chain group 3-9 f
A food chain shows how organisms obtain energy and nutrients by consuming other organisms. Food chains begin with autotrophs, like plants, that produce their own food. Herbivores then eat the plants, and carnivores eat the herbivores or other carnivores. This continues with increasing trophic levels until reaching top predators with no natural predators. At each level some energy is lost, with decreasing amounts of energy being passed to higher levels.

Food chain & food web
Food chains represent the transfer of energy from one organism to another as each consumes the next in line. A food web incorporates all possible food chains in an ecosystem and shows their interconnectivity. Producers, like plants, harness energy at the base of food chains while consumers, such as animals, feed on other organisms for sustenance and decomposers break down waste and remain into nutrients.
Food web (1) 2
The document discusses food chains and food webs. It defines producers, consumers, and decomposers. It explains how energy and nutrients flow through ecosystems via trophic levels from primary producers to higher level consumers. Food webs are more complex than linear food chains and illustrate interconnecting feeding relationships in a community. Destabilizing food webs through human activities can negatively impact ecosystem functioning.
Food web presentation
Food webs show the feeding relationships between organisms in an ecosystem. They can be represented topologically to simply show relationships, or as flow webs to show the strength of interactions. Examples of different food webs include soil food webs describing underground communities, aquatic food webs of water systems, and forest food webs comprising producers, consumers, and decomposers. Food webs are important because they distinguish producers and consumers, identify animal relationships and food sources, and provide stability to ecosystems by sustaining life.
Food chains and food Webs
This document provides information about ecology and the environment. It defines key ecological terms like environment, habitat, producers and consumers. It explains how organisms are adapted to their environments and how energy flows through ecosystems. Food chains and webs are described as the transfer of energy from producers, like plants, to primary, secondary and tertiary consumers. The document outlines different types of consumers - herbivores, carnivores, omnivores and detritivores. It also discusses trophic levels and explains that only about 10% of usable energy is transferred between each level.
the food web and food chain
Producers like plants are autotrophs that can produce their own food. There are three types of consumers - herbivores that eat plants, carnivores that eat meat, and omnivores that eat both plants and meat. Decomposers break down dead materials and waste to recycle nutrients back into the environment for producers. Together these organisms are linked in a feeding order of producers, consumers, and decomposers.
Food web presentation
Plants are producers that make their own food through photosynthesis. Energy and nutrients are transferred as herbivores eat plants, and as carnivores consume herbivores and other carnivores, forming a food chain. A food web shows how different food chains interconnect as organisms fill different roles as producers, primary consumers, secondary consumers, tertiary consumers, omnivores, or decomposers to cycle energy and matter in an ecosystem.
food chains and food webs
1) A food chain models the flow of energy from one living thing to the next as organisms consume each other. All food chains begin with producers, such as plants, that obtain energy from the sun.
2) If one organism in a food chain is removed, all other organisms in the chain are affected as the energy flow is disrupted.
3) Multiple interconnected food chains form a more complex food web. Like food chains, food webs also begin with energy from the sun and producers, and the removal of any organism can impact the entire web.
Powerpoint food webs, carbon cycle
The document discusses the interdependence between living organisms through food chains, food webs, and nutrient cycles. It provides examples of how plants and animals rely on each other, with bees and flowers as a prime example. Decomposers like bacteria and fungi also play a key role in breaking down dead organisms and recycling nutrients. Any disruption in these complex interrelationships can have wide-reaching consequences on ecosystems.

An extension activity challenges students to make their own long food chain and consider how extinction would affect the chain.
FOOD CHAIN & FOOD WEB
This document discusses food chains and food webs. It defines a food chain as the transfer of energy from one organism to another as one organism eats another. There are two main types of food chains: grazing and detritus. A food chain contains producers, consumers, and decomposers. Multiple interconnected food chains form a food web. Ecological pyramids illustrate the biomass, numbers, or energy at each trophic level and typically show decreasing amounts at higher levels.
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.
Introduction to Food Chains
A food chain shows how energy flows through an ecosystem. All food chains begin with the Sun providing energy to green plants, which are producers. Producers are then eaten by primary consumers like insects and herbivores. Secondary consumers eat primary consumers, and tertiary consumers eat other consumers. Food chains illustrate the relationships between organisms as energy passes from one to the next.
Terrestrial and Aquatic Food Chains
The document discusses terrestrial and aquatic food chains. It defines food chains as relationships among plants and animals, with terrestrial food chains including land organisms like insects and bears, and aquatic chains containing ocean animals such as plankton and sharks. Examples are given of both land and water food chains consisting of four organisms with a plant at the base and higher-level predators feeding on lower organisms. Students are instructed to diagram their own terrestrial and aquatic food chains including at least four labeled organisms each.

It defines key terms like ecosystem, habitat, biotic factors, abiotic factors, producers, consumers, decomposers, predators, prey, food chains, and food webs. It explains the roles of each in energy transfer within an ecosystem. Examples are given for producers like plants, consumers like herbivores and carnivores, and decomposers like fungi and bacteria. Larger ecosystem types like terrestrial and aquatic are identified, as are specific biomes like rainforests, grasslands, and deciduous forests. Factors that determine ecosystem size such as limiting factors and carrying capacity are also outlined.
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.

Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

THEMATIC APPERCEPTION TEST(TAT) cognitive abilities, creativity, and critic...Abdul Wali Khan University Mardan,kP,Pakistan
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsAuthoring 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.

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.

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.

Food webs
- 2. we will learn today Construct food webs to know the eating habits of living things in contrasting habitats eg. Garden and desert.
- 3. By end of the lesson students would be able to Tell what are prey and predators What an arrows represent in a food web Differentiate between food chain and food web to construct a food web To tell different food webs in a different habitats
- 4. Let's recall what we studied in last lesson Can you recall what are producers? Can you construct one quick food chain Can you recall what are Consumers? Can you construct a food chain quickly Please write your answers in chat box.
- 5. Let’s have a quick recap on producers and consumers
- 8. Textbook reading Let’s read from textbook chapter 1 Page number 12 till 15
- 9. Arrow shows what in a food chain ? Arrows are used to show the feeding relationship between the animals. The arrow points from the organism being eaten to the organism that eats it.
- 10. Prey and predator Predator- An animal that captures and eats other animals Prey- The animal that is captured and eaten Predator-prey relations refer to the interactions between two species where one species is the hunted food source for the other. The organism that feeds is called the predator and the organism that is fed upon is the prey.
- 11. Food web Today we will learn about food web Food web is a connection of multiple food chains. Food chain follows a single path whereas food web follows multiple paths. From the food chain, we get to know how organisms are connected with each other. Food chain and food web form an integral part of this ecosystem. Let us take a look at the food chain and a food web and the difference between them.
- 13. Let's see the difference between food chain and food web
- 15. Food chains in different habitats Food chain depends on habitat animals are in, like for desert the plants and animals are different than of sea. So food chain would be different http://www.crickweb.co.uk/ks2science.html#foodchains ( lets learn with teacher) Click on next button on top Click on any habitat to learn about food chain of that habitat Example of seashore habitat
- 16. Let see some examples of food webs
- 17. Food web can you see producers, consumers, herbivores and carnivores
- 19. Look at this one Can you tell who is producer here Can you name some primary consumers in this food web? Name prey and predator? Please type your answers in chat box
- 20. Task to do Draw and construct a neat food web, label producers, consumers, prey and predator in your neat science copies Do workbook page number 7 ( last one is done for you ) Grass ------- Antelope ------- Cheetah Open the link of padlet wall and write one thing you learned today about food web, foo chain. Make sure you click on pink plus sign on bottom right corner, do mention your name and section https://padlet.com/zainabshiram75495/f793ty5nxe0o0g7y http://www.harcourtschool.com/activity/food/arctic_ vity.html Let's play an online game to test your knowledge, need to have flash player to play this game
