Correct option is C
Explanation:
This question is based on Optimal Foraging Theory (OFT) and the Marginal Value Theorem (MVT) proposed by Charnov (1976). This theorem describes how long a forager should stay in a resource patch before moving to a new one to maximize energy gain.
Understanding the Graph:
- The X-axis represents time (minutes).
- The Y-axis represents cumulative resource intake, which follows a diminishing returns curve.
- The curve shows that at first, resources are abundant, but as time passes, the rate of intake slows down due to resource depletion.
- T (Initial time) represents the travel time to reach a patch.
- T' (Duration in the patch) represents patch residence time, i.e., the time spent foraging before leaving for a new patch.
Information Booster:
1. T (Travel Time to Patch): The time the forager spends moving between patches, which is essential in determining optimal foraging efficiency.
2. T' (Patch Residence Time): The time spent foraging in the current patch before deciding to leave for another.
