2. Predation

Explanation:

An ecosystem is composed of biotic and abiotic components of the environment which interact with each other for mutual benefit. Predation is a biological interaction where one species feeds on the other species. It is a process of major importance in influencing the distribution, abundance, and diversity of species in ecological communities. Generally, successful predation leads to an increase in the population size of the predator and a decrease in population size of the prey. These effects on the prey population may then ripple out through the ecological community, indirectly changing the abundances of other species.
