These are the green plants also known as autotrophs and also chemosynthetic bacteria which
convert the energy during photosynthesis when oxygen is released. The rest of the biological
community is completely dependent upon the producers.
Herbivores
These animals obtain their energy by digesting plant material from the producers. Examples are
goats, cows etc.
Carnivores
: These animals derive energy from eating herbivores animals. Examples are birds, tigers and lions.
Omnivores
These animals eat plant materials and animals; they derive their energy from eating herbivores
animals. Examples are human beings and bears
Decomposers
These are small organisms like fungi; bacteria use dead plant and animal materials as food. These
organisms break down the organic substances thereby releasing compounds back into the
atmosphere.
