Question: What abiotic factor has the greatest impact on the health and biodiversity of the coral reef?

Most coral thrives in warm water, especially between 73 and 84 degrees Fahrenheit. Sunlight is also an important factor for coral reefs, as they house photosynthetic algae that make their own food by using the sun’s energy. The algae are able to provide nutrients for the coral due to their symbiotic relationship.

What abiotic factors affect coral reefs?

Abiotic Factors

  • Light: Corals need a moderate amount of sunlight in order to survive. …
  • Depth: Reef building corals must live where there are moderate amounts of light. …
  • Water temperature: Remember that corals thrive in the warm waters of the tropics. …
  • Salinity: Salinity is usually measured in parts per thousand (ppt).

What is the most important abiotic factor in a coral reef?

Sunlight is one the most important abiotic factors for marine ecosystems. It’s so important that scientists classify parts of marine ecosystems—up to three—by the amount of light they receive.

What abiotic factors affect the productivity and health of coral reef ecosystem?

As the environment of coral reefs naturally is very stable, reefs are easily affected by sudden changes of abiotic factors, like salinity, temperature, oxygen content, and water transparency.

Which factor appears to have the largest impact on coral reef health in the Caribbean?

Overfishing threatens over 60 percent of Caribbean coral reefs. Fishing above sustainable levels affects coral reefs by altering the ecological balance of the reef. The removal of herbivorous fish, which consume algae, facilitates algal overgrowth of corals.

What are the most important abiotic factors that influence your Ecoscenario?

ABIOTIC DATA. The ocean is influenced by abiotic factors in the air and water, and along the ocean bottom. Monterey Bay National Marine Sanctuary is affected by ocean currents, nutrient upwelling, and El Niño events. The shape of the seabed and the strength of waves are also important.

What abiotic factors live in the Great Barrier Reef?

Temperature and sunlight are two abiotic factors found in nearly every ecosystem, but since the Great Barrier Reef is an aquatic ecosystem, it has some additional abiotic components, including buoyancy, viscosity, light penetration, salts, gases and water density.

What are the most important abiotic features of aquatic ecosystems?

Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.

What biotic factors are impacting the Great Barrier Reef?

Biotic factors of The Great Barrier Reef are the living components of the ecosystem, they include: coral, animals (such as sea turtles, crabs, sea urchins ,fish, sharks, eels, dolphins and seals), plants (like seaweed and plankton) and bacteria.

What are 2 abiotic factors that affect the abundance and distribution of corals?

Their distribution is highly dependent on abiotic factors such as light, water temperature, and salinity. LIGHT: Coral diversity is low near the surface, reaches a maximum between 15 and 30 m, and then drops again with increasing depth. TEMPERATURE: Corals require water temperature ranging between 18 C and 30 C.

What factors influence coral reef health?

There are numerous stress factors that can detrimentally impact the health of coral reefs. These include changes in sea surface temperature (SST) and salinity (SSS), sea level and ocean currents, nutrient availability and/or sedimen- tation rates, and light levels or surface seawater aragonite saturation (Xarag).

What factors are affecting coral reefs?

Factors that affect coral reefs include the ocean’s role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, viruses, impacts of dust storms carrying agents to far-flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal areas.

What are some abiotic factors in the ocean?

Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability. Ocean ecosystems are impacted by abiotic factors in ways that may be different from terrestrial ecosystems.

What is the greatest threat to coral reefs quizlet?

Overfishing is a major cause of coral reef destruction.

THIS IS UNIQUE:  You asked: Why do certain parts of the world tend to have more biodiversity than other places?

What are the biggest threats to coral reefs?

Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems. These threats are caused by warmer atmospheric temperatures and increasing levels of carbon dioxide in seawater.

What are the man made factors that affect the biodiversity on the coral reef?

Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.
