What is food web in short?
A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community. The food web is a simplified illustration of the various methods of feeding that links an ecosystem into a unified system of exchange.

What are the 3 food chains?
The food chain also explains the feeding pattern or relationship between living organisms. Trophic level refers to the sequential stages in a food chain, starting with producers at the bottom, followed by primary, secondary and tertiary consumers.
What are the main components of food chain?
Components of a Food Chain
- Plants – ‘base’ of the food chain.
- Herbivores – feed on plants; many are adapted to live on a diet high in cellulose.
- Omnivores – feed on both plants and animals.
- Carnivores – feed on herbivores, omnivores, & other carnivores.
- Decomposers.
- Grazing food chain.
- Detrital food chain.
What are the 5 parts of a food chain?

What is a food chain Class 7?
A food chain is a series of organisms where all the organisms are dependent on next organism as a source of food. Autotrophs prepare food by photosynthesis, heterotrophs depend on plants for food and saprophytes feed on heterotrophs and so the process goes on.
What is food chain easy?
Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.
What is a food chain Grade 2?
A food chain describes how different organisms eat each other, starting out with a plant and ending with an animal. For example, you could write the food chain for a lion like this: grass —> zebra —> lion.
