Question

why do taller trees contribute more carbon to the soil?
taller trees absorb more carbon during hurricanes.
taller trees need more carbon to quickly grow large.
taller trees contain more matter that will be added to the soil when they die.
taller trees cycle more carbon through photosynthesis.

Explanation:

Taller trees have more biomass. When they die and decompose, this greater amount of matter, which contains carbon, is added to the soil. Option 1 is incorrect as carbon - absorption during hurricanes isn't the main reason for carbon contribution to soil. Option 2 focuses on growth needs rather than soil - contribution. Option 4 is about carbon cycling in photosynthesis but not directly about carbon addition to soil upon death.

Answer:

Taller trees contain more matter that will be added to the soil when they die.
