Answer:
Explanation:
Salinity- This term refers to the salt content of water.
Salinity can be define as the total salt concentration present in water or any other liquid. It is the environmental factor which fluctuates in the oceanic water. Some of the organisms can tolerate the high salinity levels others are not adapted.
Water flow conditions- Different plants and animals need different conditions to survive. Some prefer flowing streams, and some need shallow water.
The water flow conditions can be determined by the speed of water and it's density. These conditions influence the lives of living beings such as plants and animals.
Water depth- When this factor increases, the amount of sunlight that reaches plants and animals under water decreases.
The water depth can vary among different layers and zones of the water body or aquatic biomes. The deepest zone or layers generally do not receive sunlight as the rays of sunlight are incapable of penetrating the deep water layers.
Dissolved oxygen- Life forms in aquatic biomes need this to survive.
The oxygen is the necessary element that is required for the respiration which is the vital function required for living in both terrestrial and aquatic biomes. In the water, the oxygen get dissolved from the atmosphere.
