  Coral is actually a living animal. has a symbiotic relationship (each gives something to the other and gets something back in return) With ‘zooxanthellae’ microscopic algae which live on coral [i.e. instead of living on the sea  floor, the algae lives up on the coral which is closer to the ocean surface and so … Read more Coral Reef and Coral Bleaching

FOREST ECOSYSTEM

Forest ecosystem includes a complex assemblage of different kinds of biotic communities. Optimum conditions such as temperature and ground moisture are responsible for the establishment of forest communities. Forests may be evergreen or deciduous which are distinguished on the basis of leaf into broad-leafed or needle leafed coniferous forests in the case of temperate areas. … Read more FOREST ECOSYSTEM

 BIOGEOCHEMICAL CYCLE

The elements or mineral nutrients are always in circulation moving from non-living to living and then back to the non-living components of the ecosystem in a more or less circular fashion. This circular fashion is known as biogeochemical cycling (bio for living; geo for atmosphere). Nutrient Cycling: The nutrient cycle is a concept that describes … Read more  BIOGEOCHEMICAL CYCLE
