BlogFood Web Definition Trophic Levels Types and Example Biology Diagrams The food chain starts with producers and ends with decomposers. A food chain diagram shows how energy passes within an ecosystem through organisms eating and being eaten. The diagram of the food chain class 6 and 7 is an important topic in the biology syllabus and is often asked in the examinations. An animal cell diagram is useful for A _trophic level_ is a step in the food chain that each organism occupies. In a simple food chain, it is easy to see the trophic pyramid. At the base of the food chain are the producers, and at the top of the food chain are the consumers. Each organism in a food chain represents one trophic level.
Each aspect of the food chain, including producers, consumers, and decomposers, all contribute to a more balanced flow of energy and nutrients. Brooks Mathews is an Education Writer for A-Z Animals, designing animal based unit plans that include lesson plans, activity sheets, craft/project ideas and more! Open a Creately workspace and add your peers as collaborators with edit access allowing them to work on the food web diagram with you in real-time. Define the ecosystem you want to study by identifying the specific geographical areas, climate, and habitats, and what species of plants and animals are found there.

This type of food chain is common in ecosystems where parasites play a significant role in controlling populations of other organisms. Examples of Food Chain. In the above food chain, there were three organisms involved: Grass, Deer, and Lion, so it is said to be a food chain having three steps or three links.
A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4). A food chain A grazing food chain can be either predator or a parasitic type. In a predator grazing food chain, one animal consumes another animal. The animal that is eaten is known as the prey, and the animal that eats is called the predator. In contrast, plants and animals are infected by parasites in a parasitic grazing food chain. 2. The diagram shows how mercury can accumulate in the food chain. In the sea, tiny animals and plants called plankton absorb the mercury compounds. When the plankton are eaten by small fish, the
