Answers for these questions please

A population of mice is established on an island with a population size of 10. If the population has a growth rate of 0.5, what will the population size be in ten years? Round to the nearest whole mouse. Assume this population is growing exponential. A population of deer show logistic growth, and the current population size is 100 deer. If the intrinsic growth rate (r) is 0.1, and the carrying capacity is 200 deer, what is the rate of change of the population size (dN/dt), as measured in number of deer over time? When a population that exhibits logistic growth is impacted by delayed density dependence, when would we expect a stable limit cycle to develop? This is a trick question because delayed density dependence always results in a stable limit cycle When rT is intermediate When rT is very large When rT is very small Which of the following is NOT a reason why small populations are generally at a higher risk of extinction than larger ones? Smaller populations will experience a higher level of adaptive evolution than larger ones, which can prevent them from interbreeding with other populations of the same species The effects of genetic drift are larger when populations are small, which can lead to a loss of genetic variation and a decreased chance of future adaptive evolution

Explanation / Answer

Question 1: populaion size=1435

N(t)=N0*ert =10* 2.7 0.5*10 =1435

Question 2

By logistic growth dN/Dt=rN[k-N/K]

r= Growth rate=0.1 , N=population size= 100, K=carrying capacity=200

DN/dt=0.1*100[200-100/200]

=10*[200-0.5] =10*199.5 =1995

Question 3: Option c

Question 4: Option b
