Homework Answers
Option D is wrong. The carrying capacity of a population is fixed, it doesn't change with change in growth rate.
The growth of the population becomes slow as it reaches carrying capacity because resource availability becomes low.
This equation gives rate of change of population, This equation is of logistic growth model.

1. The effects of disease in a population would be considered density dependent. True False 2.You discover a new species of salamander and after watching it through mating season, you determine that females lay between 1000-1500 eggs at a time on average. Based on this information and your knowledge of life history traits, you predict that the species also: A. has low levels of parental care. B. has a low risk of mortality at a young age. C. reaches sexual...

Quiz 5 Help Save & Exit Subrn The logistic growth model predicts that the growth rate of a population will decrease as the population size approaches the environment's carrying capacity. Under what circumstances would you predict that a population would increase in size over and above its carrying capacity? Multiple Choice When competition is high and there is a high frequency of disease and parasites When resources are declining more rapidly than reproduction is declining When high predation leads to...

The logistic growth model describes population growth when
resources are constrained. It
is an extension to the exponential growth model that includes an
additional term introducing
the carrying capacity of the habitat.
The differential equation for this model is:
dP/dt=kP(t)(1-P(t)/M)
Where P(t) is the population (or population density) at time t,
k > 0 is a growth constant,
and M is the carrying capacity of the habitat. This...

Part B Please!!
Scenario The population of fish in a fishery has a growth rate that is proportional to its size when the population is small. However, the fishery has a fixed capacity and the growth rate will be negative if the population exceeds that capacity. A. Formulate a differential equation for the population of fish described in the scenario, defining all parameters and variables. 1. Explain why the differential equation models both condition in the scenario. t time a...
