How does the water inside plants return to the atmosphere?
runoff
evaporation
precipitation
transpiration

The right answer is transpiration.

Leaves transpirate by their stomata, small pores that connect the inside of the leaf with the external environment. The plant thus uses phenomena of variations of the opening of the stomata.

Transpiration plays a major role in the water absorption of the plant. It is in fact largely thanks to it that the sap rises in the xylem.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

i didn't have the answer choices , but i tried my best.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
