What biotic factors affect coral reefs?

What are the biotic and abiotic factors in a coral reef? Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature.

What are 2 biotic factors in a coral reef?

Plants and bacteria are two other major biotic components of the Great Barrier Reef. Bacteria act as decomposers for this ecosystem, and they break down dead organic matter and convert it into energy that can be used by other living things in the ecosystem.

What are 3 abiotic factors in a coral reef?

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 factors affect 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 5 major abiotic factors in coral reefs?

Five major abiotic factors in coral reefs are water, temperature, sunlight, salt, and waves. All of these are parts of the coral reef ecosystem that are not alive but have a major impact on the conditions of that ecosystem. All coral reefs are found in ocean waters, mainly in shallow, tropical areas.

How do biotic and abiotic factors interact in a coral reef?

Explanation: Biotic Factor in coral reefs include the coral, fish, aquatic plants. … Abiotic factors include trash and/or pollution that the coral and other marine life may encounter, rocks, minerals, the water, and other non-living things in the coral reef ecosystem.

How do abiotic factors affect biotic factors in the coral reef?

Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.

Which is a biotic factor in a marine ecosystem?

In a marine ecosystem, some of the biotic factor are algae, fungi, microorganisms (such as bacteria), plants, animals and corals. These living beings compete against each other for food and resources, are part of the predator-prey relation, and also include the decomposers.

What are some biotic factors in an aquatic ecosystem?

Like all ecosystems, aquatic ecosystems have five biotic or living factors: producers, consumers, herbivores, carnivores, omnivores, and decomposers.

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 4 reasons coral reefs are disappearing?

Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world.

How does deforestation affect coral reefs?

Deforestation can cause high amounts of soil erosion. With rainfall the loose soil finds its way into coastal waters through waterways. The muddy freshwater smothers the coral, blocking light and damaging coral tissue, which can lead to bleaching and deterioration of the reef and its ecosystem.

How does agriculture affect coral reefs?

Agriculture negatively impacts coral reefs. Chemicals used by farmers, such as pesticides and fertilizers, runs off the land when it rains. … Secondly, plowing land can cause sediment to enter the water system. When it ends up in the ocean, it also negatively impacts coral reefs because it can smother the corals.
