Consider an area in which plants change from one group of species to another group of species over a distance of 20 cm. How might this scale of variation affect two herbivores-aphids (very small insects) and moose (large mammals)?

Question

Quizplus · Accepted Answer

The scale of variation of 20 cm is very small and would likely have a stronger impact on very small organisms like aphids than on larger organisms like moose. The change in plant species over this small distance could significantly impact the survival and reproduction of aphids that rely on specific plant species for food and habitat, while it may not have as significant an impact on the much larger moose.
