The document describes the food chain and the different levels within it. Producers, like plants, use sunlight to produce their own food. Consumers, including primary, secondary and tertiary consumers eat other organisms for food and move energy through the chain. Decomposers break down dead organic matter and release nutrients back into the system.
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.
Energy flow in ecosystem
It is quite interesting to note that the only producer of food in the entire world is PLANT. All others are consumers, and depend only on plants to provide food to all the living organisms and species.
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.
Dondoyano, glemefer
The food chain shows how organisms transfer energy by consuming other organisms. Producers like plants use photosynthesis to convert sunlight into chemical energy. Primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers. All organisms eventually die and are decomposed by decomposers, recycling nutrients and completing the food chain. Disruptions to the food chain can impact populations if a food source disappears due to overhunting or overfishing.

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.
Miller section 3.2 (producers & consumers)
Primary producers are organisms like plants, algae and certain bacteria that can capture energy from sunlight or inorganic chemicals and convert it into energy-rich compounds. They are essential to the flow of energy through ecosystems as other organisms consume them. Consumers rely on primary producers and other organisms for energy and nutrients. They are classified based on their food sources and include carnivores, herbivores, omnivores, detritivores and decomposers like bacteria and fungi. Consumer categories in nature are often not strict, as organisms may consume a variety of food sources.

The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Trophic Levels
Organisms in food chains are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers.
Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.
Plants are the most familiar type of autotroph, but there are many other kinds. Algae, whose larger forms are known as seaweed, are autotrophic. Phytoplankton, tiny organisms that live in the ocean, are also autotrophs. Some types of bacteria are autotrophs. For example, bacteria living in active volcanoes use sulfur compounds to produce their own food. This process is called chemosynthesis.
The second trophic level consists of organisms that eat the producers. These are called primary consumers, or herbivores. Deer, turtles, and many types of birds are herbivores. Secondary consumers eat the herbivores. Tertiary consumers eat the secondary consumers. There may be more levels of consumers before a chain finally reaches its top predator. Top predators, also called apex predators, eat other consumers.
Consumers can be carnivores (animals that eat other animals) or omnivores (animals that eat both plants and animals). Omnivores, like people, consume many types of foods. People eat plants, such as vegetables and fruits. We also eat animals and animal products, such as meat, milk, and eggs. We eat fungi, such as mushrooms. We also eat algae, in edible seaweeds like nori (used to wrap sushi rolls) and sea lettuce (used in salads).
Detritivores and decomposers are the final part of food chains. Detritivores are organisms that eat nonliving plant and animal remains. For example, scavengers such as vultures eat dead animals. Dung beetles eat animal feces.
Decomposers like fungi and bacteria complete the food chain. They turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. Decomposers complete the cycle

This PowerPoint presentation discusses the topic of food chains. It introduces the student presenting, Renjini L, the optional subject of natural science, and the topic of food chains. The presentation contents include producers, consumers separated into primary, secondary and tertiary, and decomposers. It defines producers as organisms that can make their own food, typically green plants. Consumers are defined as organisms that depend on producers for food, and are further divided into herbivores, carnivores and omnivores. Decomposers help decompose dead plants and animals. The presentation includes pictures and discusses the directional transfer of energy through a food chain and the interdependence of organisms.
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.
Science 4
This document discusses energy flow through ecosystems. It defines producers as organisms like plants and algae that capture energy from sunlight through photosynthesis to produce food. Consumers obtain energy by eating other organisms and include herbivores, carnivores, and omnivores. Herbivores eat only plants, carnivores eat only animals, and omnivores eat both. Secondary consumers are carnivores that prey on other animals. Decomposers break down dead organisms and waste, recycling nutrients and completing the energy cycle.
Energy Flow
Plants and other autotrophs are called producers because they convert inorganic material to organic compounds through photosynthesis. However, the term producer is misleading as plants produce organic compounds primarily for themselves, not just for animal consumption. Energy flows through ecosystems in a non-linear web, with only about 10% of energy transferred from each trophic level to the next as it is lost to the environment.
Earth Science. Biosphere ppt
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on explaining the biosphere and related concepts like ecology, biotic and abiotic factors, food chains, and food webs. The biosphere is made up of all living things that interact with each other and non-living things. Energy from the sun is passed between organisms through food, starting with producers and moving up through herbivores, carnivores, and decomposers. Food chains connect to form more complex food webs in 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. Overlapping food chains form food webs. Predators hunt prey for food. Energy pyramids illustrate that less energy is available at higher trophic levels.

Lesson 1: Ecosystem (Fourth Quarter Period)
1) An ecosystem consists of biotic and abiotic components that interact with each other. Biotic components include producers, consumers, and decomposers. Producers make their own food through photosynthesis. Consumers cannot produce their own food and depend on producers or other consumers. Decomposers break down dead organisms.
2) Energy flows through an ecosystem via food chains and webs. Producers are the first link while consumers occupy higher trophic levels. Only about 10% of energy is transferred between trophic levels, resulting in fewer organisms at higher levels as shown by the energy pyramid.
3) Organisms within an ecosystem engage in various interactions like predation, competition, mutualism and
Food chain
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 includes examples of food chains and defines the roles of producers, consumers, and decomposers. It also

A food chain refers to the transfer of energy from one organism to another as each organism eats and is eaten. It typically involves producers, primary consumers, secondary consumers, tertiary consumers, and decomposers. Producers, like plants, get their energy from the sun. Primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers are apex predators that eat secondary consumers. Decomposers break down dead organisms and waste to recycle nutrients back into the system.

Plants obtain their nutrition through autotrophic nutrition, also called photosynthesis. During photosynthesis, plants use energy from sunlight, carbon dioxide from the air, and water to produce glucose and release oxygen. Animals obtain nutrition through heterotrophic nutrition, either holozoic where they feed on other organisms, saprophytic where they feed on dead and decaying matter, or parasitic where they live in or on a host organism.
iGCSE Biology Section 4 Lesson 2.pptx
This document discusses feeding relationships in ecosystems. It defines producers as organisms that can make their own food, such as plants, and consumers as organisms that cannot make their own food and must consume other organisms. Consumers are further divided into herbivores, carnivores, and omnivores based on whether they eat producers, other consumers, or both. Food chains show the transfer of energy as each organism eats the one below it. Producers are at the start of food chains, and consumers can be classified based on their trophic level as primary, secondary, or tertiary consumers depending on what they eat.
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.
Ecosystems: Feeding relationships
Producers, consumers, and decomposers all play important roles in ecosystems. [1] Producers like plants and algae produce their own food through photosynthesis. [2] Consumers such as animals are heterotrophic and obtain carbon compounds by eating other organisms. [3] Decomposers including fungi and bacteria break down dead organic matter and release nutrients back into the environment.
