Organisms depend on one another through food chains and webs. Producers like plants generate food from sunlight. Decomposers break down dead matter. Consumers include herbivores that eat plants, carnivores that eat other animals, and omnivores that eat both. Food chains show how energy passes from organism to organism as each is consumed. Overlapping food chains form food webs. Predators hunt prey for food. Energy pyramids illustrate that less energy is available at higher trophic levels.

Food chains
Plants harness energy from the sun through photosynthesis and are called producers. Many animals eat plants as vegetarians and are primary consumers. Carnivores and omnivores that eat these primary consumers are secondary consumers. A basic food chain has producers (plants), primary consumers (herbivores that eat plants), and secondary consumers (carnivores that eat primary consumers).
Food chain
A food chain is a linear sequence of organisms in a food web where each organism transfers energy by being eaten. Producers, like plants, are the first links as they get energy from the sun. Herbivores eat producers. Carnivores eat herbivores or other carnivores. Omnivores eat both plants and animals. Detrivores and decomposers break down dead organisms, recycling nutrients. If one link is removed, it affects the entire 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.

This document provides information about food chains. It begins by defining a food chain as a sequence of organisms through which energy flows as each organism obtains energy from the one below it in the chain. Producers, such as plants, are at the bottom of the food chain as they can produce their own food. Herbivores, as primary consumers, eat the producers. Carnivores eat herbivores or other carnivores. Omnivores both eat plants and other animals. Decomposers, like fungi and bacteria, break down waste and dead organisms, recycling nutrients in the ecosystem.

The document discusses food chains and how energy passes from producers to consumers. It explains that plants get energy from photosynthesis, and are eaten by herbivores as primary consumers. Carnivores that eat herbivores are secondary consumers, and carnivores that eat other carnivores are tertiary consumers. Omnivores eat both plants and animals. Decomposers break down dead matter and release nutrients back into the food chain. The document provides examples of food chains and online resources for students to learn more.
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.
Habitats and foodchains
An ecosystem refers to all the plants and animals that live together in an environment and interact. Different ecosystems can exist close together and some animals belong to multiple ecosystems. All living things are adapted to their environment and habitats in ways that help them survive, such as how seals are adapted to aquatic life. Food chains show what organisms eat other organisms or plants, and start with producers like plants. When one part of a food chain is disrupted, it can negatively impact other parts of the ecosystem. Human activities like habitat destruction and pollution are common reasons why some animal populations become endangered or extinct.

Decomposers break down waste and release nutrients. Food webs show interconnected food chains and the flow of energy and matter through an ecosystem.
Producers
Organisms get energy from their ecosystem, with some making their own food through photosynthesis like producers such as plants, grasses, shrubs, trees and algae. Producers use energy from sunlight to produce their own food through photosynthesis, providing oxygen and food for other organisms. Some organisms take in food as consumers while others break down wastes as decomposers.

Food Chains and Food Webs (PowerPoint)
This document discusses food chains and food webs. It explains that a food chain begins with an energy source like a producer and is made up of different trophic levels including producers, primary consumers, secondary consumers, and tertiary consumers. Producers make their own food, primary consumers eat plants, secondary consumers eat herbivores, and tertiary consumers eat other carnivores.
Introduction to energy flow
The document introduces the concepts of energy flow through food chains and webs in ecosystems. It explains that the sun is the ultimate energy source and that plants convert the sun's energy to food through photosynthesis. This energy then flows to consumers as herbivores eat plants and carnivores eat herbivores or other carnivores. Detritivores and decomposers break down dead organic matter, recycling nutrients and energy back into the system. Food chains illustrate a single path of energy transfer, while food webs show the multiple feeding relationships in an ecosystem.

Biology 3 2
Autotrophs, also known as producers, are organisms that can capture energy from sunlight or chemicals and use it to produce their own food from inorganic compounds through photosynthesis or chemosynthesis. Heterotrophs, also known as consumers, are organisms that obtain energy by consuming other organisms and rely on the food chain and food web for energy transfer. Energy flows in one direction through an ecosystem from the sun or inorganic compounds to producers, then to various consumers in a less efficient trophic level transfer.

Unit 3 lesson 1 food chains
This document defines key terms related to ecosystems, including producers, consumers, decomposers, food chains, and food webs. It provides examples of each trophic level and discusses how energy flows through ecosystems. Producers, like plants, capture energy from the sun that is then consumed by primary, secondary, and tertiary consumers. Decomposers, such as bacteria and fungi, break down dead organisms and waste. While nutrients cycle through the ecosystem, most energy is lost as heat at each trophic level, with only 10-15% transferred to the next level.
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.
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.
Energy flow
In ecology, energy flow, also called the calorific flow, refers to the flow of energy through a food chain. In an ecosystem, ecologists seek to quantify the relative importance of different component species and feeding relationships.
A general energy flow scenario follows:
Solar energy is fixed by the photoautotrophs, called primary producers, like green plants. Primary consumers absorb most of the stored energy in the plant through digestion, and transform it into the form of energy they need, such as adenosine triphosphate (ATP), through respiration. A part of the energy received by primary consumers, herbivores, is converted to body heat (an effect of respiration), which is radiated away and lost from the system. The loss of energy through body heat is far greater in warm-blooded animals, which must eat much more frequently than those that are cold-blooded. Energy loss also occurs in the expulsion of undigested food (egesta) by excretion or regurgitation.
Secondary consumers, carnivores, then consume the primary consumers, although omnivores also consume primary producers. Energy that had been used by the primary consumers for growth and storage is thus absorbed into the secondary consumers through the process of digestion. As with primary consumers, secondary consumers convert this energy into a more suitable form (ATP) during respiration. Again, some energy is lost from the system, since energy which the primary consumers had used for respiration and regulation of body temperature cannot be utilised by the secondary consumers.
Tertiary consumers, which may or may not be apex predators, then consume the secondary consumers, with some energy passed on and some lost, as with the lower levels of the food chain.
A final link in the food chain are decomposers which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. They also break down plants, herbivores and carnivores that were not eaten by organisms higher on the food chain, as well as the undigested food that is excreted by herbivores and carnivores. Saprotrophic bacteria and fungi are decomposers, and play a pivotal role in the nitrogen and carbon cycles.
The energy is passed on from trophic level to trophic level and each time about 90% of the energy is lost, with some being lost as heat into the environment (an effect of respiration) and some being lost as incompletely digested food (egesta). Therefore, primary consumers get about 10% of the energy produced by autotrophs, while secondary consumers get 1% and tertiary consumers get 0.1%. This means the top consumer of a food chain receives the least energy, as a lot of the food chain's energy has been lost between trophic levels. This loss of energy at each level limits typical food chains to only four to six links.
Energy flow in ecosystems
1) Energy from the sun is captured by producers like plants through photosynthesis and converted into chemical energy stored in organic molecules. 2) Primary consumers, like herbivores, obtain this energy by consuming producers. Secondary consumers eat primary consumers. 3) Energy is lost at each trophic level, with only about 10% transferred between levels. This limits the length of food chains and the number of organisms an ecosystem can support.
Relationships in ecosystems
Organisms in an ecosystem depend on one another through food chains and webs. Producers like plants generate their own food through photosynthesis. Decomposers break down dead matter. Consumers cannot produce their own food and include herbivores, carnivores, and omnivores. Food chains show the transfer of energy from producers to consumers. Multiple overlapping food chains form a food web. Predators hunt prey for food, with energy decreasing at each trophic level in the energy pyramid model.
ECOSYSTEM And its characteriisticspptx
This document provides an overview of key concepts related to ecosystems, including:
- An ecosystem consists of both biotic (living) and abiotic (non-living) components that interact. Examples of ecosystems include forests and oceans.
- Energy from the sun or chemicals flows through an ecosystem via food chains and webs. Producers like plants harness energy, which is then consumed by herbivores, carnivores, and decomposers at increasing trophic levels.
- Organisms within an ecosystem engage in various interactions such as competition, predation, and symbiosis. While competition occurs when organisms require the same resources, symbiotic relationships can be mutualistic, commensalistic, or parasitic in nature
Energy transfer in the ecosystems
This document discusses energy transfer in ecosystems through food chains, webs, and pyramids. It explains that producers like plants obtain energy through photosynthesis, and consumers obtain energy by eating producers or other consumers. A food chain outlines the sequence of energy transfer from the sun to producers to primary, secondary, and tertiary consumers. Scavengers and decomposers also play roles in recycling nutrients and matter back into the ecosystem.

Food and energy in the environment
This document discusses how organisms obtain energy and their roles in ecosystems. Producers, like plants, generate their own food through photosynthesis. Consumers, such as herbivores, carnivores and omnivores, obtain energy by eating producers or other consumers. Decomposers, including bacteria and fungi, break down dead organisms and cycle nutrients back into the environment. Food chains and webs represent the transfer of energy as organisms consume other organisms. Producers are the first level, while consumers and decomposers occupy higher levels, with less available energy at each step.
Food chains and food webs
Carnivores obtain food by killing and eating other animals and require many calories, so individual carnivores must eat many other animals over the course of a year. Herbivores only eat plants and have specialized digestive systems to digest various plant materials. Omnivores eat both plants and other animals or animal products like eggs. A food chain shows a single path of energy transfer between organisms in an ecosystem from producers to primary, secondary, and tertiary consumers. A food web depicts the complex network of interconnected food chains in an ecosystem.

2) Organisms are assigned to trophic levels based on how they obtain energy. Producers are the first level, followed by primary, secondary, and sometimes tertiary consumers. Decomposers recycle nutrients by breaking down dead organisms.
3) Energy is lost at each trophic transfer as heat, so only about 10% of energy is passed up to the next level. This limits the number of trophic levels an ecosystem can support and results in fewer organisms at higher levels in the energy pyramid.
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.
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.
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.
Energy flow in ecosystems
The document discusses energy flow through an ecosystem. It explains that grass, frogs, snakes, grasshoppers and hawks interact through a food chain where grass is eaten by grasshoppers which are eaten by snakes or frogs which may then be eaten by hawks. It also defines producers as organisms like grass that can produce their own food, consumers as organisms that cannot produce their own food and eat other organisms, and decomposers as organisms like bacteria and fungi that break down waste and dead organisms.
CHMSC Lab. Sch. Sci. 6 Food Chain
The document discusses food chains and the different types of organisms within them. It explains that food chains begin with producers, which are plants that can produce their own food through photosynthesis. Producers are then eaten by consumers like herbivores, carnivores and omnivores. Consumers can be primary or secondary depending on their place in the food chain. Scavengers feed on dead organisms, and decomposers like bacteria and fungi break down tissues of dead organisms.
Queency powerpoint
1) Food chains describe the transfer of energy from producers to consumers in an ecosystem. Producers such as plants get energy from the sun which is then consumed by primary, secondary, and tertiary consumers.
2) Organisms obtain food through predation, symbiosis, and mutualism. In predation, one organism hunts another for food. Symbiosis describes living together, including parasitism where one benefits at the expense of the other, commensalism where one benefits without affecting the other, and mutualism where both benefit.
3) Disruptions to the food chain, such as the loss of a population like frogs in a pond, can negatively impact other populations that depend on

This document discusses food chains and food webs. It defines a food chain as a linear sequence showing how nutrients and energy are transferred between organisms, beginning with producers and ending with decomposers. Food chains can be grazing chains that start with plants or detritus chains that start with dead organic material. Multiple interconnected food chains form a more complex food web. The food web shows a more accurate representation of the flow of energy between trophic levels in an ecosystem.
Food chain
A food chain describes the transfer of energy from organism to organism in an ecosystem. Primary producers like plants trap solar energy through photosynthesis and are eaten by primary consumers like herbivores. These primary consumers are then eaten by secondary consumers such as carnivores or omnivores. Tertiary consumers may also exist and consume secondary consumers. Food chains interconnect to form complex food webs as most organisms have more than one food source. Energy from the sun is passed from producers to consumers in a food chain.
flow of energy.pptx Environmental science
This document describes the different types of organisms in an ecosystem and their roles. It explains that producers, such as plants and algae, use energy from sunlight or chemicals to produce food. Consumers, such as animals and fungi, eat the producers or other organisms. Decomposers, like bacteria and fungi, break down dead organisms and waste and release nutrients back into the environment for producers to use again. Together these groups transfer energy through food chains and webs in ecosystems.
Food chain
The food chain is a linear sequence of organisms where nutrients and energy are transferred from one organism to another as they are consumed. It begins with producer organisms like plants, then primary and secondary consumers that eat the producers, and ends with decomposer organisms like bacteria that break down waste. A food chain explains the feeding relationships between organisms at different trophic levels in an ecosystem. Multiple interconnected food chains form a more complex food web that better represents the flow of energy and interactions between species in an environment.
Energy flow in ecosystem
1) Energy from the sun powers photosynthesis in green plants, which convert carbon dioxide, water, and sunlight into glucose.
2) This chemical energy from glucose is transferred through ecosystems as organisms eat each other, forming food chains.
3) Producers like plants capture energy from the sun which is then consumed by primary consumers like herbivores, and passed up through secondary and tertiary consumers in a trophic pyramid, with decomposers recycling nutrients.

Within ecosystems, energy can be added, stored, or transferred through food chains. Producers, like plants, convert solar energy into chemical energy through photosynthesis. Primary consumers, or herbivores, eat producers. Secondary consumers are carnivores that eat primary consumers. Tertiary consumers are large carnivores that eat secondary consumers or omnivores that eat both plants and other animals. Decomposers break down dead organic matter and release energy and nutrients back into the ecosystem. As energy passes between trophic levels some is lost as heat, so less energy is available at higher levels of the food chain.
Biopptonefficencyoftrophiclevels 110322083013-phpapp01
1) An ecosystem consists of a community of interacting organisms and their non-living environment. Energy flows through ecosystems in one direction via food chains and webs from producers to various consumers.
2) The transfer of energy between trophic levels is inefficient, with typically only 10% of energy being transferred to the next level. This results in pyramids of biomass and numbers that narrow with higher trophic levels.
3) Ecological efficiency describes the overall efficiency of energy transfer between trophic levels, calculated as the product of various consumption, assimilation, and production efficiencies at each trophic level. However, it can be difficult to measure these values precisely in natural ecosystems.

Organisms depend on one another through food chains and webs. Producers like plants generate food from sunlight. Decomposers break down dead matter. Consumers include herbivores that eat plants, carnivores that eat other animals, and omnivores that eat both. Food chains show how energy passes from organism to organism as each is consumed. Multiple overlapping food chains make up a food web. Predators hunt prey for food. Energy pyramids illustrate that less energy is available at higher trophic levels.
What is ecology 090901135227
The document discusses ecosystems, including definitions of ecology, ecosystems, biotic and abiotic factors. It addresses key ecosystem concepts like food chains, nutrient cycles, interactions between organisms, and different biomes. Students are asked to define ecosystems, categorize examples as biotic or abiotic, and describe a local ecosystem and interactions. The document provides material for learning about ecosystems and having students demonstrate their understanding through discussion and assignments.
Activities
This document provides instructions for an activity where students will observe and collect other plant-like living things found in the school grounds using magnifying lenses. Students will then answer questions about what they observed and collected, comparing and contrasting these organisms with what was studied in lower grades. Questions probe characteristics, habitats, needs for survival, similarities and differences between groups of organisms.
Ecosystemslesson2 biotic and abiotic
Ecosystems are formed through the interaction between biotic and abiotic factors. Biotic factors refer to living or once-living parts, while abiotic factors are non-living parts. Major abiotic factors that shape ecosystems include sunlight, water, air, and soil. Sunlight provides warmth, energy for photosynthesis, triggers seasons and daily activity patterns. Water is essential for all life and transports nutrients. Air supplies oxygen and carbon dioxide. Soil contains nutrients for plants to grow in and supports organisms living in the ground.
