Coral Reefs
Overfishing of herbivorous (plant-eating) fish can also lead to high levels of algal growth. Photo: Damselfish add to the destruction of coral reef as they create holes in the ... , when an algal bloom occurs near a coral reef, it may smother parts of the coral reef. The algae block the sunlight required by the zooxanthellae in the coral to complete photosynthesis. This ...

Coral Reefs
Nearly half of the carbohydrates that result from photosynthesis are used by the coral polyps. Zooxanthellae use the remainder for growth and reproduction. Coral ... other organisms. This can lead to algal blooms that essentially can smother parts of a coral reef, blocking the sunlight required by the zooxanthellae for photosynthesis. This has been a problem ...

US Coral Reefs - Imperiled National Treasures
Most hard corals also host symbiotic algae, a long-standing and successful partnership. These algae provide them with an additional food source through photosynthesis. Coral reefs are formed by corals that secrete hard calcareous (aragonite) exoskeletons, giving them structural rigidity. These colonial hard corals form elaborate fi nger-shaped, branching, or ...

Coral reefs of Hawai'i
Unfortunately, nearshore coral reefs often receive the brunt of these impacts. Because corals contain internal microscopic plants called zooxanthellae, they receive much of their energy from sunlight via photosynthesis. In addition, their calcareous skeletons are fragile and grow slowly. As a result, corals are easily broken are sensitive to changes in the quality of coastal waters. For example, ...
