Why are corals key for the environment?
Coral reefs support more species per unit area than any other marine environment including about 4 000 species of fish 800 species of hard corals and hundreds of other species. … Healthy coral reefs support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation.
Why it is a keystone species?
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species the ecosystem would be dramatically different or cease to exist altogether. … The ecosystem would be forced to radically change allowing new and possibly invasive species to populate the habitat.

Why are coral reefs important for climate regulation?
Like terrestrial rainforests corals may be involved in a regulatory cycle that helps regulate local climates. Coral production of DMSP increases in response to stress caused by rising water temperatures basically acting as anti-oxidants for cellular protection.

Are humans keystone species?
Ecologists have identified numerous keystone species defined as organisms that have outsized ecological impacts relative to their biomass. Here we identify human beings as a higher-order or ‘hyperkeystone’ species that drives complex interaction chains by affecting other keystone actors across different habitats.
What is the role of coral in the food chain?
Primary Producer
Coral reefs need to live close to the surface of the water in order to collect the light energy from the sun. These unique organisms create their own food by transferring the sun’s energy into chemical energy using photosynthesis. In this ecosystem the primary producers are plankton and algae.
