Focuses on factors affecting population size over time
If you study how nitrogen is transferred from one species to another in a lake, you are a(n):
Ecosystem ecologist (interaction of the community with physical factors)
A scientist is examining how fast a colony of pathogenic bacteria grows on a culture plate when it's been given certain nutrients. This scientist could best be described as a(n):
Population ecologist (same species being examined)

Depending on its range, the diet of a population of black bears might be predominantly animal materials or it might be predominantly plant materials. There is a scientist who is studying how a mostly-animal and a mostly-animal and a mostly-plant diet differentially influence the development of bear cubs. Such a scientist would best be described as a(n):
