Do You Know Everything About Animal Diversity?

Nimals compete for food, water, territory and (intra-species only) mates. Natural selection reduces inter-species competition to a degree as it reinforces behavioural adaptations like feeding at different times of day, eating different types of food or feeding at different heights where there are trees. This means that two or more species can occupy the same territory and competition will only be for water.
