Ecosystem

An ecosystem is a self-sustaining biotic and abiotic unit of interactions. It is composed of complex communities of plants, animals, and other organisms that interact with each other and their environment. Ecosystems are important because they provide essential services for humans, such as clean water, food, and shelter, as well as aiding in climate regulation and supporting biodiversity. Ecosystems are also essential for sustaining life on the planet, as they maintain the balance of elements and energy in the environment. Humans rely on these ecosystems for their sustenance and must take care to protect them from harm in order to ensure their health and wellbeing.
