Similarly, if you see the population of other organisms, you will find many organisms living together. None of the organisms in this world can survive alone. This interaction between populations gives rise to population interaction. Let us learn further.

Lichens are a classic example of mutualism in between fungi and algae. Even plants and animals show good mutualism. Plants need some agents for pollination and seed dispersal. And these agents are the animals. Animals, in turn, are rewarded with the nectar or the fruits of the plants. But, even in mutualism , there are some cheater species, which may not reward the other species. This leads to co-e
