Detailed explanation-1: -What Do Organisms Compete For? Organisms compete for the resources they need to survive-air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).
Detailed explanation-2: -You may think of the ladybug as a simple predator preying on the aphids; however, by eating the aphids, the ladybug is also protecting the plant. In return, the plant indirectly provides the ladybug with a steady supply of food. This is an example of mutualism, a relationship in which both organisms benefit.
Detailed explanation-3: -If we were in the warm waters of the Pacific or Indian Oceans, we’d likely spot an excellent example of mutualism: the relationship between clownfish and sea anemones. In a mutualistic relationship, both species benefit. Sea anemones live attached to the surface of coral reefs.
Detailed explanation-4: -A mutualistic relationship is when two organisms of different species “work together, ” each benefiting from the relationship. One example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra.
