How do flora and fauna affect each other?

The flora and fauna are two ecosystems that are very closely related to each other. If the harmony is disturbed in one ecosystem, it will be reflected in another. Plants are food and shelter for animals. In turn, animals can be useful for plants, as they can pollinate the flowers of plants, as well as apply fertilizers, contributing to the rapid growth and strengthening of the root system. They can carry plant seeds over great distances, contributing to the spread of certain species. A balance must be struck for the development of both species.
