Food Chain And Food Web Examples
Food chain food web plays an important role in nature to balance our ecology.
Food chain and food web examples. Food chains and food webs are easy to get confused since they both show the movement of energy through an ecosystem. In biology and ecology, we use the terms food web and food chain. Food chain food web in a food chain, there is a straight line from producers to first consumers to second consumers to third consumers in a food web, each organism eats and is eaten by 2 or more organisms.
Many food chains make up a food web. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. In an ecosystem, plants and animals all rely on each other to live.
In the african savannah food web shown here, we can see multiple arrows pointing to different animals. Now that you are familiarized with what is food chain at trophic levels, let us understand food web. To really understand a food web, you need to look at a food chain first.
A chain follows just one path from a plant to, for example, an eagle. This food web consists of several different food chains. Occasionally, a single organism is consumed by many predators or it consumes several other organisms.
Phytoplankton and algae form the bases of aquatic food webs. For example, a red fox likes to eat rabbits and birds. Here are some examples of food chains:
A thrush, which is a type of bird, like to eat both worms and snails. A food chain represents only one dimension of food or energy flow through an ecosystem and shows a simple relationship between components. Most organisms in food web have different populaces of producer species which are eaten by any number of consumer organisms.
