Food Chain Examples Biology
Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web.
Food chain examples biology. The source of all food is the activity of autotrophs mainly photosynthesis by plants. The butterflies feed on nectar and at the same time are the food of other insects that are the food of bats. The food chain is an ideal representation of flow of energy in the ecosystem.
They are consumed by carnivores flesh-eaters. The following is an example of a food web. A food chain usually starts with.
Grazing food chain is a type of food chain in which energy at the lowest trophic level is acquired via photosynthesis. Some examples of food chains in the following desert ecosystems illustrate the important role of these xerophytes. Herbivores plant-eaters come next in the chain.
The decomposers which are the fungi and bacteria feed on the organic matter to meet the energy requirements. Food chain is a chart showing the flow of energy food from one organism to the next beginning with a producer. The arrows between each item in the chain always point in the direction of energy flow - in other words from the food to the feeder.
Every food chain must start with a producer or autotroph an organism that makes its own energy through a process called photosynthesis. This food feeds herbivores called primary consumers. For example grass seed is eaten by a vole which is eaten by a barn owl.
A food chain always begins with producers. Some common food chains are mentioned below. The food chain is the transfer of energy from one living being to another.
