Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
On Earth, water cycles through the atmosphere, oceans, land and organisms. By what process does most of the water in plants return to the environment?
A
evaporation from roots
B
evaporation from leaves
C
condensation on the leaves
D
diffusion from the roots
Explanation: 

Detailed explanation-1: -Evapotranspiration also includes transpiration, which is the water movement from the soil to the atmosphere via plants. Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.

Detailed explanation-2: -The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Detailed explanation-3: -Surface runoff it is Water flowing over land masses. During this process, the waters travel as rivers and streams that eventually return to the ocean, or become freshwater lakes and ponds. Sometimes, water falls back to the soil from plant transpiration (another process known as evapotranspiration).

Detailed explanation-4: -In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.

Detailed explanation-5: -The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
