An ecosystem consists of a habitat, living things, and relationships between them. It includes terrestrial and aquatic ecosystems. All living things obtain food by interacting with other components in the ecosystem, such as through food chains. Human activity like overusing resources, pollution, and causing extinction of species is harming the planet in various ways.
