- https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step. 6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of thesearrow_forwardDistinguish between the exponential and logistic growth of a population and describe the nature of their growth curves.

Define and give an example of a population crash.arrow_forwardThe carrying capacity (K) is the maximum population size that can be supported or sustained by a given environment. Which of the following statements about the carrying capacity is NOT true? Select one: a. We can think of K as some "average" value that a given environment can support. b. Environmental fluctuations cause the carrying capacity to fluctuate over time. c. Once a population reaches its carrying capacity, the size of the population remains constant. d. When a population overshoots K, individuals die due to lack of resources.arrow_forward
