What are the biotic factors in 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 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 3 abiotic factors in a coral reef?
Some of the abiotic factors that are specific to coral reefs are oxygen, water , carbon dioxide, sand, rocks, shells, temperature,light, hard substance, and waves.
What is biotic in a coral reef?
Do you remember what biotic means? It means life. Biotic factors are living or once living components of a community. Coral reefs are complex ecosystems . There are many different biotic factors that affect coral reefs.
Is a shell biotic or abiotic?
The definition of “abiotic” is “non-biological.” A seashell is made by a living organism, therefore it is biotic. In the sea, shells come from creatures like clams, oysters, mussels, scallops, whelks, conchs, periwinkles, and other sea snails.
How biotic and abiotic factors work together?
Abiotic and biotic factors combine to create a system or, more precisely, an ecosystem, meaning a community of living and nonliving things considered as a unit. In this case, abiotic factors span as far as the pH of the soil and water, types of nutrients available and even the length of the day.
What interactions exist between biotic and abiotic elements?
One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis, the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.
What are the 4 biotic interactions?
Biotic interactions can occur within or among species, be positive or negative, and cover a wide range of interactions including predation, commensalism, mutualism, resource competition, and parasitism [1].
What is a abiotic factor example?
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.
