Now you'll tie together what you've learned.
Read over the information on what's happening with the study of lionfish (you can ignore the questions on this page).
Answer the question here on Canvas.
18)Based on what you've learned about the invasive lionfish population in the Atlantic, and the various types of factors that may limit population growth, which ONE factor (intraspecific competition, interspecific predation, disease & parasites, social behavior) do you think would be the MOST limiting? Why?

- Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.arrow_forwardFor each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.arrow_forwardIn Glacier Sea over the past 5 years the moon jelly population has been INCREASING.

- Figure 47.16 Which of the following statements is not supported by this graph? There are more vulnerable fishes than critically endangered and endangered fishes combined. There are more critically endangered amphibians than vulnerable, endangered and critically endangered reptiles combined. Within each group, there are more critically endangered species than vulnerable species. A greater percentage of bird species are critically endangered than mollusk species.arrow_forwardDRAW IT In the Chesapeake Bay estuary, the blue crab is anomnivore that eats eelgrass and other primary producers as wellas clams. It is also a cannibal. In turn, the crabs are eaten byhumans and by the endangered Kemp’s Ridley sea turtle. Basedon this information, draw a food web that includes the bluecrab. Assuming that the top-down model holds for this system,describe what would happen to the abundance of eelgrass ifhumans stopped eating blue crabs.arrow_forwardFor each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.arrow_forward
