Coral reef

Coral reefs are beautifully seen in shallow areas, such as the Australia’s eastern coast, also known as the “The Great Barrier Reef”. The reef covers an area over 300,000 square kilometers. Amazingly enough, the Great Barrier Reef also covers wide range of ocean depth. People consider that the coral reef is the most complex ecosystem on Earth. Abiotic Components

There are two major abiotic factors, Temperature and Sunlight. The Great Barrier Reef is an aquatic ecosystem, in which it has more abiotic factors. The additional abiotic factors are “buoyancy, viscosity, light penetration, salts, gases and water density.” (Batema, 2014) Biotic components

The Great Barrier Reef’s major biotic components are Plants and Bacteria. The bacteria is able to create energy by breaking down dead organic matter and then converting it. Once it’s turned into energy, other living things that live in the ecosystem can use it. Plants also can create energy by converting the sun light into energy for food and to serve food for primary consumers. (Batema, 2014) Biogeochemical cycle

The components in numerous forms flow from the nonliving, also known as abiotic, to the living, also known as biotic, components of the biosphere and back to the nonliving again. For all the living things that live in the Great Barrier Reef to survive, all the chemical elements that make up living cells must be recycled continuously. (Batema, 2014) The Carbon Cycle

The biosphere contains carbon, in which is continuously reused in geologic time. The Great Barrier Reef is essential to the carbon cycle of the planet. It is because by taking calcium ions and dissolved carbon dioxide from the water and turning it into calcium carbonate forming the reefs hard skeletons. This allows our oceans to become a sink for the carbon dioxide in the atmosphere. (Eoearth, 2011; Batema, 2014) Nitrogen...
