Environment & Ecology
Eco-Systems
Natural ecosystems include the forests, grasslands, deserts, and aquatic ecosystems like ponds, rivers, lakes, and the sea. Man-modified ecosystems include agricultural land and urban or industrial landuse patterns. The living community of plants and animals in any area together with the non-living components of the environment - such as soil, air and water - constitute the ecosystem. Some ecosystems are fairly robust and are less affected by a certain level of human disturbance. Others are very fragile and are quickly destroyed by human activities.
