Food Chain Definition Environmental Science

Food chain.

Food chain definition environmental science. For example grass produces its own food from sunlight. The food chain describes who eats whom in the wild. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

Energy is not created or destroyed. Usually there are four trophic levels present in the ecosystem because level. The chain of organisms which involves transfer of energy from one trophic level to next trophic level is called as food chain.

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 an apex predator species like grizzly bears or killer whales detritivores like earthworms or woodlice or decomposer species such as fungi or bacteriaA food chain also shows how organisms are related to each. When two or more than two types of food chains get connected or interlinked with each other then they form a food web. In ecology a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next.

Food chain - ecology a community of organisms where each member is eaten in turn by another member. However the adverse effects on the environment food systems and people along the food supply chain are already evident. However there are several reasons why a food chain may become disrupted.

This is usually a green plant because plants can make their own food by photosynthesis. A food chain is a pathway that represents the exchange of energy from one organism to another. It is introduced generally in Class 3 Science and students get to explore it in detail further till Class 9th.

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. The flow of food or energy in an ecosystem is called food chain. Plants which convert solar energy to food by photosynthesis are the primary food source.
