House martins (depicted on the right) feeding their young in the nest are clear examples of central-place foragers. Imagine that a house martin travels to two different patches to collect meals for its chicks. The patches are identical except that one is farther from the nest. According to the marginal value theorem, which statement best describes how an optimally foraging house martin should behave?



It should stay longer in and collect a larger load from the more distant patch

Explanation:

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

a. the production of carbon dioxide through the process of photosynthesis
