Food Chains and Food Webs
What is the difference between food chains and food webs?
A food chain is largely the linear in nature. It means it goes in a straight line. A food web is all-encompassing.
A food chain shows one specific example of how energy moves through the energy cycle. All food chains start with producers like a tree. If a rabbit eats off the tree, it takes energy from the tree. If a snake eventually eats the rabbit, it gets energy from the rabbit. If the snake is eaten by an eagle, the eagle gets energy from it. This was a simple example.
On the other hand, A food web shows all of the possible connections in a given ecosystems energy cycle. A food web consists of two or more food chains and they are interconnected.
Quick Facts: –
- Plants are called producers as they make their own food by a process called photosynthesis.
- All animals including humans are consumers as they cannot make the food they eat.
- The Sun is the most important element in the entire food system as without Sun, the plants would not grow and there would be no animals without plants.
- In a food chain, each organism occupies a Trophic level. It is the number of energy transfers between this organism and the basic input of the chain.
- Most of the food chains have links no more than 4 or 5.
