Q 3 a) What is a food chain? Give one example

Answer 1

Answer:

food chain : it is a natural process

Explanation:

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.

☛ The sequence of living organisms in a community in which one organism consume another organism to transfer food energy is called food chain.

☛ In simple words , a list of organism (living beings) showing who eats whom is called a food chain.

☛ A food chain represents a single directional or unidirectional transfer of energy.

☛ The study of food chains in an area or habitat helps us in knowing various interaction among the different organisms and also their interdependence.

☛ For example:- simple food chain operating in a grassland or forest can be represented as :-

$\rm\:Grass\longrightarrow\:Deer\longrightarrow\:Lion$
