Explanation

b: The minimum number of individuals required to establish a viable population Explanation

Explanation

c: The total number of habitat cells Explanation

Explanation

d: The annual mortality rate of the pest Explanation

Explanation

3. What is the primary effect of increasing the dispersal rate (d) in the simulator?

a: The pest spreads more slowly across the habitat. Explanation

Explanation

b: The pest population becomes extinct immediately. Explanation

Explanation

c: The pest spreads more rapidly through the habitat. Explanation

Explanation

d: The habitat length decreases. Explanation

Explanation

4. Why are mathematical models useful for studying biological invasions?
