why do coral reefs have such high productivity quizlet

The first aspect to understand is that coral reefs are extremely complex ecosystems that depend on many parameters having to be … Start studying geog coasts kq3. Coral bleaching accompanied some of the mortality events prior to the 1980s during periods of elevated sea water temperature, but these disturbances were geographically isolated and restricted to particular reefs zones. Natural disasters such as hurricanes, tropical storms, tsunamis, and landslides have the potential to be the source of a tremendous amount of marine debris. Scientists have long wondered how corals manage to eke out a living in the nutrient-poor waters they tend to occupy. Coral reef ecosystems also contribute to the human geography of a region. These eroded fragments of coral (along with bony fragments of organisms such as foraminifera , mollusks, and crustaceans) create a soft sand known as coral sand. Marine ecosystems generally have low productivity. The average gross primary productivity of a coral reef system is 4200 (g C m-2 yr-1). Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms.Thousands of species of corals have been discovered; some live in warm, shallow, tropical seas and others in the cold, dark depths of the ocean. Areas where cold currents well up continuously from the sea bed, such as the Galapagos coast, are constantly supplied with nutrients and hence are highly productive. This productivity explains why estuaries attract such huge numbers of birds. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Why do tropical coral reefs prefer high wave energy locations? Productivity of coral reefs 1. Coral reefs have some of the highest productivity rates in the world because of their abundance of life. Indeed, this coral reef paradox has … Prior to the 1980s, most mass coral moralities were related to non-thermal disturbances such as storms, aerial exposures during extreme low tides, and Acanthaster outbreaks. Coral reefs are oases of high primary productivity in barren tropical seas, and reef-building organisms have changed the face of the earth by creating entire archipelagoes of islands and, over geological time, landforms that have become incorporated in continents. Coral reefs are some of the most diverse ecosystems in the world.
