How is population growth is determined from birth, death, immigration, and emigration?
r = (b i) - (d e)
What is r = (b i) - (d e)?
Population growth is determined from birth, death, immigration, and emigration.
How do you sketch basic graphs showing exponential and logistic growth?
Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.
What does Exponential growth produce a J-shaped curve, while logistic growth produces an S-shaped curve mean?
How to sketch basic graphs showing exponential and logistic growth.
What are the variables N, N0, r, t, K, dN/dt stand for in the growth models?
The different variables in the growth models.
What are the different variable in growth models?
N, N0, r, t, K, dN/dt
What is density dependent?
In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population.
What is population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population?
Density dependent
What is density independent?
In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population.
What is, In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population?
Density independent
How do exponential and logistic growth models change when r, N, or K change?
They fluctuate either height wise or exponentially wise.
In population ecology, density-dependent processes occur when population growth rates are regulated by the density of a population.
How exponential and logistic growth models change when r, N, or K change.
