Food Chain Definition Environmental Science

However the adverse effects on the environment food systems and people along the food supply chain are already evident.

Food chain definition environmental science. Food chain in ecology the sequence of transfers of matter and energy in the form of food from organism to organism. The organisms that feed on dead organic matter or detritus are known as detritivores or decomposers. That is they can form one of the links in a food chain.

Some invasive species were actually brought in as unsuccessful attempts to control other invasive species. Those organisms which join with the food chain are termed as Trophic levels. Learn vocabulary terms and more with flashcards games and other study tools.

Plants which convert solar energy to food by photosynthesis are the primary food source.

The food chain describes who eats whom in the wild. These detritivores are later eaten by. The food chain can also end one step further with decomposers like bacteria or worms which would process the predator species once it dies depending on the definition.

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 describes the feeding relationships of different organisms in a linear fashion. 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.
