Biological environment
The biological environment includes all the living organisms.They are further differentiated on the basis of their nutritional relationships into producers,consumers and decomposers.
The photosynthetic bacteria and green plants are included in the category of producers because they synthesize their own complex organic food from water, minerals, carbon dioxide and sunlight through photosynthesis.
All animals, including man come under the category of consumers because they can not synthesize their organic requirements or food of their own. They have to depend upon plants for their food.
The decomposers like microorganisms decompose by the action.
