Food Chain Definition Geography

A food chain almost always begins with a green plant producer which is eaten by an animal consumer.

Food chain definition geography. 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. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. Food losses are the highest for fruits and vegetables where on average 50 to 60 of all the production is lost along the supply chain implying that only 40 to 50 of what is being harvested end up.

The algae is the producer. This occurs when one organism consumes another organism. Some Apex predators include sharks lions and owls.

Any animal that is on top of the food chain is called an Apex Predator. The arrow means is eaten by and shows the flow of matter and energy along the food chain. McGraw-Hill Dictionary of Scientific Technical Terms 6E Copyright 2003 by The McGraw-Hill Companies Inc.

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 other creatures are producers they get their energy from the sugars glucose made by consumers. Plants which convert solar energy to food by photosynthesis are the primary food source.

Therefore the food chain and food web are interrelated. This information should not be considered complete up to date and is not. It begins with producer organism follows the chain and ends with decomposer organism.

It converts sunlight energy into glucose. For example grizzly bears only have access to salmon at certain times of the year while in the early spring diets are largely root-based and herbivorous. Many food chains make up a food web.
