It carries oxygen to the rest of the body. It can also remove carbon dioxide.
Many trees are evergreen so that plants can photosynthesize right away when temperature rise, many trees that have needle-like leaves which shape losses less water and sheds snow more easily than broad leaves waxy coating on needle-like prevent evaporation need-like leaves are dark in color allowing solar heat to absorbed many trees have branches that droop downward to help shed excess snow to keep the branches from breaking.
It is crucial to study ocean microbes because THEY CONTROL THE MAJOR BIOGEOCHEMICAL CYCLES THAT KEEP EARTH'S BIOSPHERE IN BALANCE.
The ocean is made up of many microbes, which play important role in the process of biogeochemical cycling of various elements. For instance, microbes play very important role in the biogeochemical cycling of carbon and nitrogen. In the nitrogen cycle, the microbes are responsible for breaking down the protein molecules that are found in the body of dead plants and animals. The proteins are broken down into constituent amino acids, which are then released back into soils. The soil used these ammonia as sources of nitrogen for growing plants.
