Primary Production

Primary Production

Primary Production is the production of organic compounds from carbon dioxide and sunlight, principally through the process of photosynthesis, forming the basis of the food web.

Algae are aquatic, photosynthetic plant-like organisms and include calcareous macroalgae, fleshy macroalgae, turf algae, and crustose coralline algae. Carbon storage and cycling is the ability of an ecosystem to utilize, process, and store carbon. Climate regulation is the process by which ecosystems process and store carbon, which can modulate atmospheric levels of carbon dioxide. Contact Uses, such as biological additions, physical damage, and biological harvesting, are activities in which humans create pressures through direct contact with the ecosystem. Cultural services are the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, recreational opportunities, aesthetic experiences, sense of place, and educational and research opportunities. Discharges are the intentional or unintentional distribution of chemicals, debris, or other pollution, into the environment as a consequence of human activities. Ecosystem monitoring and restoration refers to responses to directly alter the condition of the reef ecosystem through restoration or remediation activities, setting limits on degradation through biological criteria or water quality criteria, or improving knowledge through monitoring, mapping, and scientific research. Ecosystem services are the benefits people obtain from ecosystems . Landscape Changes are alterations of the natural landscape through human activities, including coastal development, shoreline armoring, impervious surfaces, deforestation, or soil disturbance, which can alter water flow patterns and lead to pollutant runoff into coastal systems. Light is the level of visible and ultraviolet solar radiation that penetrates the water column. Mangroves are various kinds of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics � mainly between latitudes 25� N and 25� S. Nutrients are essential elements needed by plants and animals for growth and primarily include nitrogen, phosphorous, and potassium, as well as minor nutrients such as calcium, magnesium, or zinc. The Reef Ecosystem includes a suite of abiotic variables that form the physical and chemical environment. Plankton are any plants or animals that are too small to actively move against ocean currents. Pressures are human activities that create stress on the environment. Primary Production is the production of organic compounds from carbon dioxide and sunlight, principally through the process of photosynthesis, forming the basis of the food web. Provisioning services are the products or ecosystem goods obtained from ecosystems, including seafood, genetic and biochemical resources, pharmaceuticals, ornamental resources, and water resources. The state of the Reef Ecosystem is the condition, in terms of quantity and quality, of the abiotic and biotic components including physical, chemical, and biological variables. Reef Habitat is the abundance, distribution, and condition of the benthic components of the reef ecosystem. Reef Inhabitants are all of the motile components of the reef ecosystem, including fish, invertebrates, marine reptiles and mammals, and are quantified by their abundance, distribution, and condition. Reef Life is the abundance, distribution, and condition of the biological components of the coral reef ecosystem. Regulating Services are benefits obtained from ecosystem processes that regulate the environment, including erosion regulation, natural hazard regulation, and climate regulation. Responses are actions taken by groups or individuals in society and government to prevent, compensate, ameliorate or adapt to changes in Ecosystem Services or their perceived value. Seagrasses are flowering plants that grow in marine, fully-saline environments. Socio-Economic Drivers include the sectors that fulfill human needs for Food & Raw Materials, Water, Shelter, Health, Culture, and Security, and the Infrastructure that supports the sectors. Supporting services are ecological processes that indirectly benefit humans by maintaining a functional ecosystem for the production of other ecosystem goods and services. Valuation is the process of estimating the worth, merit, or desirability of benefits derived from ecosystems. A wetland is an area of land whose soil is saturated with moisture either permanently or seasonally.

CMap Description

Algae and wetland plants, including seagrasses and mangroves, obtain nutrients through primary production. Stony coral also obtain nutrients through symbiotic algae called zooxanthellae. Primary production forms the foundation of the aquatic food web, providing complex habitat and resources for invertebrates and fish, which ultimately benefits humans through provision of goods, such as seafood, and recreational opportunities. Because photosynthesis converts atmospheric CO2 into biomass, primary production also contributes to climate regulation. Many of the same economic sectors that benefit from primary production also create pressures on the reef through harvesting, as well as contributing to coastal development and pollution. Decision-makers can better understand the value of reef primary productivity through valuation methods. Scientific monitoring and research can be used to better understand rates of primary production under various environmental conditions.
