Question

What is a food chain give example

Answer 1

a food chain means a series of organisms in which each is eaten by the next member in the chain.every food chain starts with the green plants.

eg: 1. grass→deer→tiger
2.grass plant→grasshoper→lizard→bird.

and the number of interconnected food chains are called food web.

Answer 2

A food chain is a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the sun to make their food) and ending at apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria). A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level. A food chain differs from a food web, because the complex network of different animals' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time.
