Population Growth
R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.

- The information indicates that the dinoflagellate population studied is Select one: a. Use the following information to answer the next question. To investigate the ecological strategies of dinoflagellates, a type of microscopic algae, researchers set up some aquariums of dinoflagellates. Dinoflagellates were introduced into each aquarium at day 0. After 15 days, the dinoflagellate population bloomed (had a rapid population increase) in each aquarium. Within 48 hours of the appearance of the "blooms," few dinoflagellates remained. C. b.
