Why does sugar move to the roots through the phloem during the summer months?

Biology

Pressure Flow. The mechanism by which sugars are transported through the phloem, from sources to sinks, is called pressure flow. At the sources (usually the leaves), sugar molecules are moved into the sieve elements (phloem cells) through active transport.

_____ in tropical countries will cause many more extinctions per acre than it would in higher latitudes
Digiron [165]

(Please note that this answer is more of a matter of my own opinion than anything, and under most circumstances, none of the above would be wrong. Please do not hold it against me if this answer is wrong. If it is wrong, then the answer would probably be A)

What is the purpose of a wasp
Inessa [10]
In early summer wasps, like bees, pollinate plants and flowers as they feed on nectar. If we were to eradicate all wasps, it would cause more problems than it would solve. So, wasps do serve a purpose, and despite being a problem at certain times of the year, they are a beneficial insect.
