In an ecosystem, two factors are being classified which are the abiotic and the biotic factors. Both of these factors play an important role in order to balance the ecosystem and maintain the harmony of the living things therein. The environment includes the abiotic factors which are the sunlight, weather, water, air, and all other factors which are not living but contribute to the growth and development of the living ones.
