What three human activities are threatening both coral reefs and coastal ecosystems?
- Physical damage or destruction from coastal development dredging quarrying destructive fishing practices and gear boat anchors and groundings and recreational misuse (touching or removing corals).
- Pollution that originates on land but finds its way into coastal waters.

Why is biodiversity important in coral reefs?
Biodiversity ensures that some life will continue to survive even after major catastrophic events that wipe out many species. Biodiverse ecosystems also provide services for example nursery habitat to edible fish species which would be difficult and expensive to reproduce artificially.
Why are coral reefs and mangroves important?
Together the coral reef and mangrove ecosystems form a barrier that protects shorelines from the destructive forces of wind waves and driven debris. These living structures decrease the erosion and physical damage that can often impose significant economic and environmental costs on coastal communities.
Why are coral reefs important and why are they dying?
What are 5 importance of coral reefs?
protect coastlines from the damaging effects of wave action and tropical storms. provide habitats and shelter for many marine organisms. are the source of nitrogen and other essential nutrients for marine food chains. assist in carbon and nitrogen fixing.
What is the difference between coral and coral reef?
Why are coral reefs often compared to tropical rainforests?
Coral reefs are often called the “tropical rainforests of the sea” for their astounding richness of life. Due to their structural complexity corals are one of the most productive ecosystems on Earth providing important services to mankind including fisheries coastal protection medicines recreation and tourism.
Why is the relationship between the corals and the algae in the coral reefs considered?
The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return the algae produce oxygen and help the coral to remove wastes.

5. If tropical ocean generally supports very little life why do coral reefs contain such astonishing biological diversity and density? … These single-celled plant-like organisms facilitate the rapid biochemical deposition of calcium carbonate into the coral skeleton.
Why are coral reefs highly productive?
Coral reefs’ high productivity has been attributed mainly to photosymbioses between the coral animal and algae of the family Symbiodiniaceae with recognition that the host can increase algal photosynthesis by concentrating nutrients and enhancing the efficiency of light absorption.
