- https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html 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?You are observing two different species of caterpillars feeding on green shrubs in the Sacramento Mountains. One has bright red and yellow stripes, the other is a nondescript greenish color. You hypothesize that the two species have adopted different antipredation strategies. 1) What would these two strategies be called? 2) Which species would you predict is noxious to potential predators and which species is palatable? 3) Which species would you predict would alter its behavior more in the presence of predators? Why?1. Answer the following questionsa)How long will it take for a dolphin population to be reduced by 50% if the intrinsic rate of increase is -.04?b)In the last 70 years the blue whale population decreased from 340,280 to 4,727. What is the intrinsic rate of decrease (r)? c)If the current intrinsic rate of increase for blue whales is .1, how long will it take the current population of 4,727 to climb back to 340,280?
