who does bacteria survive in the abyssal zone of the ocean

The movement of water is also important in many aquatic biomes. The water temperature affects the organisms’ rates of growth and the amount of dissolved oxygen available for respiration. In addition to light, solar radiation warms bodies of water and many exhibit distinct layers of water at differing temperatures. The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems because it controls productivity through photosynthesis. While there are some abiotic and biotic factors in a terrestrial ecosystem that shade light (like fog, dust, or insect swarms), these are not usually permanent features of the environment. As one descends deep enough into a body of water, eventually there will be a depth at which the sunlight cannot reach. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water, on its own, absorbs light. The aquatic medium-water- has different physical and chemical properties than air. In the case of aquatic biomes the abiotic factors include light, temperature, flow regime, and dissolved solids. Like terrestrial biomes, aquatic biomes are influenced by abiotic factors. Summarize the characteristics of standing water and flowing water in freshwater biomes.Compare the characteristics of the ocean zones.Describe the effects of abiotic factors on the composition of plant and animal communities in aquatic biomes.By the end of this section, you will be able to:
