The Secrets of the Deciduous Forest

What is a primary ecological importance of deciduous forests?

• They are the primary habitat for polar bears.

• They provide significant oxygen production through photosynthesis.

• They are the main source of desert sand.

How do deciduous forests contribute to the water cycle?

• By absorbing water from the atmosphere.

• By storing water in tree trunks.

• By releasing water vapor into the atmosphere through transpiration.

• By preventing rainfall with their canopy.
