Question

Which of the following adaptations enables deciduous trees to produce more food?

Answer 1

c. leaf loss

This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms. 

Answer 2

Answer: b. stretching toward the sun

Explanation:

The deciduous forests are the biome which exhibit four distinct seasons such as winters, spring, summer and fall. Summers are warm and winters are cold.

Leaves are the main food producing organs of the plants and trees. The deciduous trees exhibit broad leathery leaves which are stretched towards the sun. Their shape allows them to obtain maximum sunlight so as to make food in the form of carbohydrates (sugars) by the process of photosynthesis. The leaves are adapted to synthesize food in all the seasons. As, in winters the deciduous trees may receives low sunlight.
