Question

How is water distributed through the biosphere?

Answer 1

Hint: Many essential biochemical pathways are involved in water, like photosynthesis, absorption and cellular respiration. It is also home to many species of plants, animals or microorganisms, and all the resources used by living beings are involved in cycling.

Complete answer:
• Water is the element that is most plentiful in living organisms.
• The human body consists of around 70 percent water, for instance, and jellyfish are 95 percent water.
• Around three-quarters of the Earth's atmosphere is covered by oceans and holds about 97% of its water.
• The Earth's largest water bodies are the oceans.
• Solar radiation stimulates the evaporation of water from the ocean.
• In this way, about 80 percent of the evaporated water in the hydrologic cycle exists in the air and about 52 percent of this comes in the form of rain back to the ocean.
• In the biosphere, water is circulated in a cycle known as Water cycle.
• Water is consumed by their roots that are used in photosynthesis, but by the transpiration, it is often lost from their leaves.
• Through evaporation from the surface and from various other causes, water often returns to the atmosphere.
• The amount of precipitation obtained by a region in general helps decide what kinds of plants are going to thrive there.

Note: Through seepage from the earth, water from the land reaches the oceans. It trickles down to the water table from the top. This surface and rock water-saturated zone is considered groundwater and water seeps from the ground water to the ocean. Water also enters the ocean from the atmosphere through runoff. Runoff from the soil requires river flow as well as melting glaciers or snowfields.
