Note:
In a food chain involvement of different species and animals in a single habitat is being observed but every organism depends on each other for their survival. If the producers fail to grow or primary consumers count is low or decreases then, the disruption of the food chain can happen. Ecology is the key to the diverse species and smaller groups of habitats forming chains together are called ecosystems.
