Food chains essay

Producers are also known as autotrophs as they make their own food. Producers are any plant or other organisms that produce their own nutrients through photosynthesis. For example, green plants, phytoplankton and algae are some examples of producers in a food chain.

The transfer of food energy from the producers, through a series of organisms with repeated eating and being eaten, is known as a food chain. The green plants utilise the radiant energy of the sun, which is transformed to chemical form, by synthesizing the complex organic molecules. Green plants absorb a portion of this radiant energy.

Every level in a food chain is known as a trophic level. The food chain consists of four major parts, namely: The Sun: The sun is the initial source of energy, which provides energy for everything on the planet. Producers: The producers in a food chain include all autotrophs such as phytoplankton, cyanobacteria, algae, green plants.

The sequence of living organisms in a community, in which one organism consumes another organism to transfer food energy, is called a food chain. In simple words, a list of organisms (living beings) showing “who eats whom” is called a food chain.
