An ecosystem refers to an area where both abiotic (solar energy, temperature, soil, and water) and biotic (natural plants, animals, and humans) constituents interlinked with each other. There might prevail in both aquatic and terrestrial ecosystems on this Earth. In an aquatic ecosystem, rocks provide shelter and plants supply oxygen to the fish population. A balance is achieved when biotic and abiotic constituents are in a cooperative relationship.
