Description of Biotic Component

Sub-division under biotic component 

1. Producers [Autotrophic]
2. consumers [Hetrotrophic] 
3. Decomposers   

Producers - Producers are autotrophic because they prepare their food by its own by the 
process of photosynthesis e. g. Plants. Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar.

Consumers - Consumers are heterotrophic because it depends on other. Consumers have to feed on producers or other consumers to survive. Deer are herbivores, which means that they only eat plants (Producers). Bears are another example of consumers.

Decomposers - Decompose dead and decay material ,e.G. In form of bacterias,fungi. Decomposers are the garbage men of the animal kingdom; they take all the dead animals and plants (consumers and decomposers) and break them down into their nutrient components so that plants can use them to make more food.
