Answer:
Trees and Plants
Explanation:
Trees and plants in our communities are responsible for the maintenance of our ecosystem. There activities include carbon sequestration ( Plants remove carbon from the atmosphere and fix it in their tissues), generation of oxygen (they generate oxygen as a by-product when photosynthesis occurs), control of soil erosion ( it is well known that plants and trees help in erosion control. in fact places with trees and good vegetation cover rarely suffer the effects of erosion) and habitat provision for wildlife (countless species make the trees and plants their abode or habitat i.e where they live).
This shows how important plants and trees are to our ecosystem.
