Answer #1

Logistic growth model is used to examine decreases in the rate of population growth as popolation size approaches carrying capacity..

logistic growth is when a population growth increase till it reaches the carrying capacity. When it reaches to the carrying capacity the growth is decresed significantly.

Intrinsic rate is when a population size increase without any density dependent factors.

Exponantial growth shows a j shaped curved, it mean a popultion size increse exponentialy when resource is unlimited.

survivorship curve depicts the survial diagram of different age group of a population.

so. only logistic growth model consider the carrying capaticy as a limiting factor for a population growth.

Population Growth Equation In the population growth equation, the letter “r” is defined as the per capita rate of increase, which is the difference between the per capita birth rate (the number of offspring produced per unit of time by an average member of the population) and per capita death rate (average number of deaths in the population per unit time). What does the value of “r” indicate about a population? All of the following characteristics are typical of a...

Growth of a population can be represented by simple mathematical models. Write the equation for exponential population growth. Write the logistic equation for population growth. Explain in your own words the meaning of the additional term in the logistic equation. Populations may not grow exactly as predicted by the logistic equation. Discuss one reason for this.

DIFFERENTIAL EQUATIONS PROBLEM Consider a population model that is a generalization of the exponential model for population growth (dy/dt = ky). In the new model, the constant growth rate k is replaced by a growth rate r(1 - y/K). Note that the growth rate decreases linearly as the population increases. We then obtain the logistic growth model for population growth given by dy/dt = r(1-y/K)y. Here K is the max sustainable size of the population and is called the carrying...

A class of models for population growth rates in marine fisheries assumes that the harvest from fishing is proportional to the population size. One such fishery uses the following quadratic model, expressed in function notation. G(n) = 0.5n - 0.2n2. Here G is the growth rate of the population (in millions of tons of fish per year), and n is the population size (in millions of tons of fish). Calculate G (1.64)

Suppose a population of fish at a farm follows logistic growth. The per capita birth rate is 0.7 fish per day, the per capita natural death rate is 0.2 fish per day, and the carrying capacity is 20000. Fish are harvested at a constant rate of 7000 fish per week. Find the equilibrium solutions to the equation.
