In biology, biotic components can be described as the living components of an ecosystem. Abiotic components can be described as the non-living components of an ecosystem. Both, the biotic and abiotic factors are important in maintaining a stable ecosystem whether it be a terrestrial ecosystem or an aquatic ecosystem.
Some of the abiotic factors which affect the distribution of the aquatic life are:
<em>Amount of light: </em>The area which will receive more light will result in greater biodiversity. This is because there will be more number of plants in this area of the water and more plants means that there will be more aquatic animals present to feed on these plants.
<em>Water flow rate: </em>Some organisms in the water are sensitive to high flow rate. More diversity will be seen in areas where the water flow is stable.
<em>Temperature: </em>Although many of the fishes are cold-blooded, yet there will be greater diversity where the temperature will be moderate.
Some of the biotic factors which affect the distribution of the aquatic life are:
<em>Predators: </em>If there are more number of predators than the preys, then the prey diversity will have a serious threat.
<em>Aquatic plants: </em>There will be more aquatic biodiversity in the areas where there will be more aquatic plants.
Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock.
