Food Chain Examples Biology
The source of all food is the activity of autotrophs mainly photosynthesis by plants.
Food chain examples biology. It shows the flow of energy and materials 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. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web.
A couple of examples of the food chain could be the following. Every food chain must start with a producer or autotroph an organism that makes its own energy through a process called photosynthesis. Here are some examples of food chains.
During photosynthesis energy from the sun is. The hawk is a predator and the frog is its prey. They are consumed by carnivores flesh-eaters.
Mahogany tree --- caterpillar --- song bird --- hawk. Food chains also exist under water. A typical example of this type of food chain is illustrated below.
For example grass seed is eaten by a vole which is eaten by a barn owl. Food chain is a chart showing the flow of energy food from one organism to the next beginning with a producer. A food web is all of the food chains in an ecosystem.
Grass Cow Human. The frog is a predator and the grasshopper is its prey. It is a chain where producers make food continues with consumers or animals who eat the food and ends with the top predator.
