What do the results suggest about ways that milkweed bug populations are limited in nature?

Temperature.

Explanation:

Temperature was the only limiting factor that controls and limits the size of the population of milkweed bug  in the nature because these milkweed bug are very sensitive to temperature. Little increase or decrease in temperature can cause adverse effect to the population f milkweed bug in that environment. Milkweed bugs need food, water, space, shelter and a mate in order to survive a well as increase in population of milkweed bug.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
