The answer is cytologist.
A cytologist is an expert in cytology. Cytology is a branch of life sciences that studies cells, including their structure, function, and chemistry. Thus, the cytologist is expert in cell function and structure. Therefore, every process in which cells are involved, such as processing sugars, would be a research target for the cytologist.
<span>A. abiotic component</span>
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
Watersheds are important because the surface water features and stormwater runoff within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Everything upstream ends up downstream.
Answer:
Animals needs oxygen's to survive and plants need carbon dioxide to survive. The ozone layer reflects harmful UV rays from the sun to protect the things living on Earth.
