why do coral reefs have high productivity


Wetlands and Nature. sources: Answers (2) Moshe 20 April, 14:52. Reasons why: very efficient relationship between coral and zooxanthellae, high flow rate of water over reef, and rapid recycling of nutrients (high levels of bacteria) 0. Beyond their intrinsic value and the roles they play in supporting vast numbers of marine species, coral reefs also provide a plethora of functions that benefit humans. The coral polyps protect the algae and supply minerals extracted direct from the water or from suspended food particles that they filter out. Moving water generally supports production. But corals are threatened by pollution and climate change. Unlike salt marshes, freshwater tidal marshes have a wide diversity of plants and so productivity depends partly on how well the particular species of plant grows. secondary consumers: Barracuda. Coral reefs are oases of high primary productivity in barren tropical seas, and reef-building organisms have … Corals are colonial animals which have within their cells photosynthetic algae. Gross Primary Productivity (GPP) is the total amount of organic matter synthesized by producers per unit area in unit time. 5. Bulletin of Marine Science, 56(2): 609-619. Biodiversity means variety and variability among the living organism's. The warm, wet conditions result in rapid decomposition and any nutrients that are present within the soil are used by the quickly growing plants, causing the soil to be left poor in nutrient content. Coral reefs rival tropical rain forests as the most species-rich communities and they support large populations of fish and other animals through very high rates of biological productivity. If reefs lose their integrity, or are otherwise destroyed, this will cease to be the case. Who is the longest reigning WWE Champion of all time? So, high levels of productivity increase biomass. Coral reefs have existed on Earth for 500 million years, providing shelter and food to many generations of ocean life. Shallow coral reefs have optimal growth rates in warm water ranging from 70-85°F (21-29°C). Coral reefs are discrete ecosystems with their own biological communities. Coral reefs are underwater structures built by tiny sea animals. The amount of precipitation determines the height of the grass, more rainfall results in higher grasses. Generally, there are about twice as many coral species in Pacific Ocean reefs, such as this Fagatele Bay reef, as in Atlantic Ocean reefs. Before we came along, the Earth didn’t suffer as much as a result of high atmospheric CO2 content or contaminants spilled into the ocean. Gross Primary Productivity and Net Primary Productivity are typically very low. (2) What are the proper definitions of Gross Primary Productivity and Net Primary Productivity? As the sun sets, however, nearly all of the heat present above and within the soil is released into the atmosphere, lowering the temperature drastically. These particles are known as sulfide minerals. Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy and rainfall is scant. Provide your opinion with justification using real-world examples. Overall, the productivity of deserts is the lowest of all the biomes. An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish and mammals can be part of a wetland ecosystem. A they're found in Northern latitudes B they have many different niches C they have an unusual uniform habitat D they are found in deep, warm Waters. Types of plants present. Society, National Geographic. Zoology 200 Coral Reefs – Ch 14 Dr. Bob Moeng 1 Coral Reefs Primary Production • Along with seagrass beds, coral reefs have highest levels of primary productivity - 1,000 gC/m2/yr (up to 5000) – Foundation for substantial diversity and biomass • Not due to phytoplankton, not due to seaweed • Not due to corals, but what’s within coral Comment; Complaint; THE OLDEST AND MOST COMPLEX LAND-BASED ECOSYSTEM ON OUR PLANET – THE TROPICAL RAINFOREST. These venting black smokers emit small particles that are created when the heat of the magma meets the cold water. ecosystem: What are the qualifications of a parliamentary candidate? A second tier or primary consumer could be a cottontail rabbit. 3. Productivity is a key benefit, because it ensures survival for the coral itself and for the various types of species it supports.
