Choose difficulty:

Beginner

Intermediate

Advanced

1. According to the mathematical model, the search time for a prey is:

a: Directly proportional to prey abundance Explanation

Explanation

b: Independent of prey abundance Explanation

Explanation

c: Inversely proportional to prey abundance Explanation

Explanation

d: Equal to the handling time Explanation

Explanation

2. What is the primary objective of optimal foraging theory?

a: To minimize predator movement Explanation

Explanation

b: To maximize the net energy gained per unit time Explanation

Explanation

c: To maximize prey diversity in the diet Explanation

Explanation

d: To reduce prey abundance Explanation

Explanation

3. According to the theory, a searching predator differs from a sit-and-wait predator because it:

a: Waits at a fixed location for prey to approach Explanation

Explanation

b: Moves throughout its habitat to locate prey. Explanation

Explanation

c: Hunts only during the night Explanation

Explanation

d: Feeds exclusively on immobile prey Explanation

Explanation

4. In the simulator, the handling time parameters (hp₁ and hp₂) represent:

a: The time required to locate prey Explanation

Explanation

b: The reproductive time of the prey population Explanation

Explanation

c: The travel time between hunting locations Explanation

Explanation

d: The time required to capture and consume the prey Explanation

Explanation

5. The overall objective of the searching predator model is to identify the strategy that:

a: Minimizes predator movement regardless of energy gain Explanation

Explanation

b: Maximizes the number of prey captured per day Explanation

Explanation

c: Maximizes net energy gain by balancing prey energy content, search costs, and handling costs Explanation

Explanation

d: Eliminates one prey species from the ecosystem Explanation
