Question

what is eco system? how it is helpful?

Answer 1

Eco system is the place where animals and humans are inter dependent on each other.
It is helpful because it lead to getting of oxygen to humans and giving carbon-dioxide to the plants which lead to growth.

Answer 2

Ecosystem services are the many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystems, grassland ecosystems and aquatic ecosystems. Collectively, these benefits are becoming known as 'ecosystem services', and are often integral to the provisioning of clean drinking water, the decomposition of wastes, and the natural pollination of crops and other plants.
