Question

Over time, a tree that once had a total mass of 300 g increased in mass by 300 kg. This increasing mass comes mostly from?

A) Photosynthesis and growth of leaves.
B) Absorption of minerals from the soil.
C) Water uptake through the roots.
D) Carbon dioxide absorption from the atmosphere.

Answer 1

The increasing mass of the tree mostly comes from photosynthesis and growth of leaves.

Step-by-step explanation:

The increasing mass of the tree mostly comes from photosynthesis and growth of leaves. During photosynthesis, plants capture solar energy and use it to convert carbon dioxide from the atmosphere into carbohydrates, which contribute to their mass. The growth of leaves also adds to the overall mass of the tree.
