The absorption and distribution of materials within an organism is a life function known as

Transport

Explanation:

Living organisms are characterized by essential day-to-day activities which they undergo to sustain their life. One of these life processes is called TRANSPORT, which involves the circulation and absorption of nutrients.

Transportation is a life process where substances synthesized or absorbed in one part of the body are carried to other parts of the body. This life process is important in plant and animals as it leads to movement of nutrient, water, mineral, gases etc. In humans, circulatory system is responsible for this process of transportation.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
