atmospheric scientists who study the lower parts of the atmosphere (primarily the troposphere) and its effects on our weather. Biochemists and biophysicists use lasers, fluorescent microscopes, and other advanced technologies to study the physical and chemical makeup of living things and of biological processes, such as heredity, cell development, growth, and disease. Biologists investigate various aspects of plant and animal life, such as their anatomy, origins, relationships, development, and functions. They can specialize in a variety of fields. For example, wildlife biologists study animals. Microbiologists analyze tiny living things that can only be seen with a microscope, such as fungi and bacteria. Chemists investigate substances at the atomic and molecular levels to determine their makeup and to see how they interact with living and nonliving things.

Soil scientists look for signs of erosion on biomass- removal test plots.
