Food chain definition environmental science. 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 bacteriaa food chain also shows how the organisms are related with. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. For example if you had a.

A food chain describes the feeding relationships of different organisms in a linear fashion. However there are several reasons why a food chain may become disrupted. 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.

Plants which convert solar energy to food by photosynthesis are the primary food source. On average food chains include around five trophic levels. 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.

A food chain is organized into trophic levels which are levels that show where an organism obtains its energy. A food chain explains which organism eats another organism in the environment. It is introduced generally in Class 3 Science and students get to explore it in detail further till Class 9th.

Every living thingfrom one-celled algae to giant blue whale sneeds food to survive. This occurs when one organism consumes another organism. That is they can form one of the links in a food chain.

And food waste is responsible for 24 of that figure. This is the simplest way of showing feeding relationships. Learn vocabulary terms and more with flashcards games and other study tools.
