Harvesting a Prey Population

Choose difficulty:

Beginner

Intermediate

Advanced

1. What does Maximum Sustainable Yield (MSY) represent?

a: The maximum number of predators supported by an ecosystem Explanation

Explanation

b: The maximum number of individuals that can be harvested indefinitely without causing population collapse Explanation

Explanation

c: The carrying capacity of the habitat Explanation

Explanation

d: The highest population density achieved during exponential growth Explanation

Explanation

2. Recruitment rate refers to:

a: The number of individuals removed by harvesting Explanation

Explanation

b: The number of predators entering the population Explanation

Explanation

c: The number of new individuals added to the existing population Explanation

Explanation

d: The carrying capacity of the environment Explanation

Explanation

3. What is the effect of increasing the harvesting rate beyond the sustainable level?

a: Population growth increases indefinitely Explanation

Explanation

b: The prey population may decline and eventually collapse Explanation

Explanation

c: Carrying capacity increases automatically Explanation

Explanation

d: Recruitment rate becomes independent of population size Explanation

Explanation

4. According to the theory, why is harvesting generally maintained below the Maximum Sustainable Yield?

a: To maximize predator populations Explanation

Explanation

b: To ensure a lower carrying capacity Explanation

Explanation

c: To reduce the risk of population, collapse and maintain long-term sustainability Explanation

Explanation

d: To eliminate competition within the population Explanation

Explanation

5. In the simulator, the parameter θ (theta) represents:

a: Predator efficiency Explanation

Explanation

b: Harvesting intensity Explanation

Explanation

c: Spatial distribution of individuals in the population Explanation

Explanation

d: Population recruitment rate Explanation
