Species diversity is defined as the number of different species present in an ecosystem ( place). The coral reef ecosystem has the highest species diversity, it has even more than Tropical rain forest.
Coral Reefs:
Coral reefs are aquatic ecosystems that are found in mainly sedimentary-free and shallow tropical ocean water.
It accounts for about 1 % of the ocean surface. However, about 25 % of the world's marine species are found in Coral reefs.

Coral reefs are mainly found in four locations:
- Andaman and Nicobar
- Lakshadweep
- Gulf of Mannar
- Gulf of Kutchch
Biomass productivity:
Biomass per unit area per year is known as Biomass productivity. The following is the list of ecosystems in decreasing order of productivity:
- Marshes or Swamps ( Highest Productivity)
- Tropical Rainforest
- Coral Reef
- Estuaries
- Temperate forests
- Tundra
- Ocean
