Biotic factors for coral reefs

The reef covers an area oversquare kilometers and includes a wide range of ocean depth, and it contains such biodiversity as to make it one of the most complex ecosystems driveman Earth, biotic factors for coral reefs. Much like any other ecosystem on Earth, the Great Barrier Reef relies on biotic and abiotic components to keep it functional and stable. Coral is the basis for the diverse animal and plant life in the Great Barrier Reef. Coral consists of polyps, which are very small creatures that reproduce to form colonies.

Biotic interactions govern the structure and function of coral reef ecosystems. As environmental conditions change, reef-associated fish populations can persist by tracking their preferred niche or adapting to new conditions. Biotic interactions will affect how these responses proceed and whether they are successful. Yet, our understanding of these effects is currently limited. Ecological and evolutionary theories make explicit predictions about the effects of biotic interactions, but many remain untested.

Biotic factors for coral reefs

Coral reefs are largely restricted to shallow tropical seas, where water is warm, nutrient poor and well illuminated for photosynthesis and where sufficient calcium carbonate aragonite exists in seawater for the precipitation of coral skeletons i. Extreme temperatures and salinities cause thermal and osmotic stress, while large amounts of sediment smother corals and block light. High concentrations of nutrients encourage algal growth at the expense of corals, while low seawater aragonite concentrations prevent net accretion of the reef framework. At local scales, the hydrodynamic regime influences reef growth, as corals are damaged by storms and wave surge. The typical abiotic environment in which reefs are found, and which determines reef distribution, is defined.

Coral reefs are in danger due to pollution from humans and climate change. Many people may not realize that humans are dependent upon the livelihood of coral reefs. Over half a billion people depend on coral reefs for food, medicine, and other resources. Coral reefs also protect the coastlines from storms and erosion. The coral reef ecosystem is made up of biotic and abiotic factors. The biotics factors are plants, crabs, fish, and coral.

Biotic factors in the coral reef ecosystem are; reef-producers, herbivorous, carnivorous and omnivorous consumers, as well as reef-decomposers. It must be noted that coral reefs are not always considered to be ecosystems, but in some cases could be viewed as micro-ecosystems because they fall within marine ecosystems , or oceans. This article discusses biotic factors in the coral reef ecosystem, as follows;. Producers in the coral reef ecosystem are organisms that are autotrophic, and can manufacture their own food using visible light from the Sun, and inorganic materials like carbon dioxide CO2 and water [ 4 ]. Being the primary producers of biomass and bioenergy , these organisms occupy the basal trophic level of the food chain and energy pyramid of coral reefs.

Biotic factors for coral reefs

Coral reefs are beautiful marine ecosystems formed in the sea from the remains of tiny marine invertebrates called coral. These reefs provide habitats for a diverse range of species. The formation of coral reefs is influenced by various biotic and abiotic factors. Abiotic factors, such as water temperature and quality, play a significant role in the development of coral reefs. In this section, we are going to discuss the abiotic factors for coral reefs. They are related to sea cucumbers and stay immobilized on solid surfaces on the ocean floor when they reach adulthood. Each coral polyp secretes calcium carbonate to build a hard exoskeleton around its body, creating a beautiful rocky shell.
