what are ecologists
An ecologist is an environmental scientist whose knowledge of the sciences is put to use in protecting the natural environment. According to the U.S. Bureau of Labor Statistics (BLS), ecologists typically do a combination of fieldwork and laboratory work (www.bls.gov).
For example, environmental ecologists study the relationships between organisms and their environments and the effects on both by factors such as population size, pollutants, rainfall, temperature, and altitude.
