Front

Which variable represents carrying capacity? Options: dN/dt, N, K, r

Back

K

Front

As K approaches N, what happens to the dN/dt?

Back

Slows/Decreases, then remains constant

Front

When is dN/dt = 0?

Back

N = K

Front

Which type of factor is an earthquake?

Back

Density independent

Front

Which type of factor is a disease?

Back

Density dependent

Front

If N = 500, K = 250, and r = 0.01, solve for dN/dt? dN/dt = rN(K-N/K)

Back

-50

• Number of elephants in 1 acre of savanna
• Number of offspring in each generation
• Number of fish in a square mile

Back

Number of offspring in each generation

Front

What happens to the growth rate as population size approaches carrying capacity?

Back

Slows

Front

How do density dependent factors affect growth rate?

Back

As population size increases, growth rate decreases
