food web ecology. Differences in carbon and nitrogen iso- tope ratios between consumers and their diet provide infor- mation on energy flows 

It shows the feeding habits of different animals that live together in an ecosystem. In the food web pictured on the left energy is passed from the grass to 

Food chains show the relationships between producers consumers and decomposers showing who eats whom with arrows The arrows show the movement of energy 

Whether a food web is big or small the organisms fall into one of two categories: producers or consumers • Producers: Producers are organisms that get their 

In a detritus food chain or food web the energy comes from dead organic matter (i e detritus) instead of green producers Therefore the flow of energy and 

the Big idea: Every living thing is part of a food chain as well as a more complex food web There are various ways to categorize organisms within an ecosystem 

Food chains illustrate how energy flows through a sequence of organisms A food web illustrates complex feeding relationships within an ecosystem

Food webs are actually made up of smaller food chains which are interconnected A food chain explains what an organism might eat and what might eat it in a 

Food chain refers to the sequence of events in an ecosystem where one organism eats another and then is eaten by another organism Food chains were first
