Ecosystem is the interaction of organisms with one another and with their environment.

In an ecosystem, the producers plays the most important role. That is the plants. Plants not only provide food, but contribute highly for the oxygen. The amount of Co2 and oxygen is stable in the ecosystem because of the plants. So discourage deforestation.

The number of consumers like herbivores and carnivores are kept in a balance by the nature itself. Hence animals should not be harmed by the humans.
