Food chain definition a series of organisms interrelated in their feeding habits the smallest being fed upon by a larger one which in turn feeds a still larger one etc. Detritus food chain is the type of food chain that starts with dead organic materials.

A simple sequence of transfer of energy in the form of food from one tropic level to another in a linear fashion is known as a food chain. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. Plants which convert solar energy to food by photosynthesis are the primary food source.

These detritivores are later eaten by. Energy is not created or destroyed. Each of several hierarchical levels in an ecosystem comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.

The Food Chain is one of the most interesting topics of Science and elucidates upon how every living being is connected together in an ecosystem. Usually there are four trophic levels present in the ecosystem because level. The food chain describes who eats whom in the wild.

For example if you had a. Food chain - ecology a community of organisms where each member is eaten in turn by another member. And food waste is responsible for 24 of that figure.

It is introduced generally in Class 3 Science and students get to explore it in detail further till Class 9th. A food chain is a pathway that represents the exchange of energy from one organism to another. Each food chain is a possible pathway that energy and nutrient s can follow through the ecosystem.
