The Processes Necessary to Sustain an Ecosystem

i. Knowledge of the Water Cycle:

Knowing how the water cycle works is a key factor in building a biome and keeping the ecosystems alive. Knowing that the radiant energy from the sun warms the air, land and water makes the species on the land (e.g. deer) easier to eat plants that grow faster. Also the precipitation that falls to the ground like hail, snow, rain or sleet cause the plants to grow since the soil becomes hydrated and thus, the biotic things in the biome grow faster and the animals living off of those organisms become more healthy and full so they can keep up the ecosystem and keep reproducing to keep the animal populations balanced.

ii. Photosynthesis and Cellular Respiration:

The organisms on my bio-dome cause an important balance between Oxygen and Carbon dioxide.

Plants on my bio-dome such as: rapid-flowering plants, fern and moss use the energy from the sun to combine Carbon dioxide from the atmosphere and water from the soil to produce sugar and Oxygen.

Carbon dioxide and water are then released and the sugars are broken down resulting in Cellular Respiration. Some of the Carbon is then released back into the environment as carbon dioxide.

All organisms including plants undergo some form of respiration. Plants like the ones in my bio-dome create 9 times the amount of Oxygen given out by Photosynthesis. And so on my bio-dome the Photosynthesis my plants create causes Oxygen to give out to the rest of the biome causing the organisms to live. The respiration given out by the animals and organisms like caribou cause carbon dioxide to be released which makes the carbon cycle work and that is a vital cycle for all things in my biomes.
