Food chain definition environmental science. Those organisms which join with the food chain are termed as Trophic levels. 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. However there are several reasons why a food chain may become disrupted.

Most ecosystems contain. Some invasive species were actually brought in as unsuccessful attempts to control other invasive species. 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.

That is they can form one of the links in a food chain. Every living thingfrom one-celled algae to giant blue whale sneeds food to survive. A food chain always starts with a producer an organism that makes food.

A food web shows multiple food chains multiple relationships and connections. Each food chain is a possible pathway that energy and nutrient s can follow through the ecosystem. In scientific terms a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other.

In other words it is the chronological order of who eats whom in a biological community. These detritivores are later eaten by. An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal.

It is introduced generally in Class 3 Science and students get to explore it in detail further till Class 9th. The definition of a food chain is a system where a small animal is the food for a larger animal which in turn is the food for an even larger animal. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other.
