Exam 7: Life History

Refer to the figure. - Seedlings of an annual plant were split into two equal treatment groups; in one group, extra fertilizer was provided, and in the other group (the control group), no additional fertilizer was added. The numbers of seeds and the average weight of the seeds from each individual plant were monitored, and these data were plotted (each point represents an individual plant). Which statement best describes the results of this study?

According to Grime's classification scheme, processes that destroy plant biomass are called

Refer to the figure. -The figure is based on data from a study of the body size and reproductive output of individual females of two different species (species 1 and species 2) over time. Each figure illustrates the growth and reproduction of each individual over its life span. Assuming these individuals are representative of their species, compare the life span and lifetime reproduction of these two species. How long did each individual survive? Compare the overall lifetime reproductive output of each individual. Which species has higher overall reproductive output, and how many eggs would the individual produce?

Four clownfish individuals of the species Premnas biaculeatus live in a single anemone. Albert measures 15 cm, Barry is 12 cm, Cindy is 8 cm, and Diane is 6 cm. If Barry died, which of the following would most likely happen?

Refer to the figure. - The figure is based on data from a study of the body size and reproductive output of individual females of two different species (species 1 and species 2) over time. Each figure illustrates the growth and reproduction of each individual over its life span. What type of reproductive strategy (semelparous or iteroparous) do these two individuals show? How did you determine this?

Which statement about clownfish is false?

Which statement about the impacts of climate change on the snowshoe hare is true?

Four clownfish individuals of the species Premnas biaculeatus live in a single anemone. Alex measures 12 cm, Blaine is 22 cm, Casey is 18 cm, and DJ is 10 cm. Which one is most likely the breeding male?

Which organisms would be most likely to be K-selected?
