Heavy water and light water are both forms of water, but they differ in their composition and properties. Light water, also known as ordinary water, is the most common form of water found on Earth. It consists of two hydrogen atoms and one oxygen atom, with the hydrogen atoms being the light isotope, known as protium.
In the case of aquatic biomes the abiotic factors include light, temperature, flow regime, and dissolved solids. The aquatic medium—water— has different physical and chemical properties than air. 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.
Heavy water lacks the characteristic blue color of light water; this is because the molecular vibration harmonics, which in light water cause weak absorption in the red part of the visible spectrum, are shifted into the infrared and thus heavy water does not absorb red light.
Although today many plants and animals are able to live on land, they still need water. This life-sustaining liquid makes up most of the animal blood or plant sap that nourishes living tissues.
The plant species which is usually found in places scientifically defined as wetlands (67-99% frequency) while sometimes it is also found in strictly terrestrial areas. Compare obligate wetland species.
many animals. Animals that depend on natural light for their vision are restricted to relatively shallow water in an ocean thousands . f meters deep. Animals that are bioluminescent, making their own light, have an interesting solution to this lack of light.
