SG 2.2 Bio

Question 1

How is population growth is determined from birth, death, immigration, and emigration

Answer 1

All of those change the population and it changes who/what can reproduce

Question 2

Where population growth is highest in exponential and logistic growth

Answer 2

Exponential is when a population has no limits and can grow infinitely. Logistic growth will hit a carrying capacity and become a flat line.

Question 3

What the variables N, N0, r, t, K, dN/dt stand for in the growth models

Answer 3

Population growth rate (N) over time (t). The population growth rate is (dN/dt). d means change. K represents the carrying capacity, and r is the maximum per capita growth rate for a population.

Question 4

Density Dependant

Answer 4

Population depends on the density of a species

Question 5

Density Independent

Answer 5

The population does not depend on the density of a species

Question 6

Density Dependant EX

Answer 6

Sea Lice depend on the density of fish population to feed on
