approximately 1,000,000,000 leaves.

Step-by-step explanation:

first, calculate the number of leaves on each tree during its lifespan.

10⁵ = 100,000

2 x 100,000 = 200,000

each tree will have 200,000 leaves in its life span.

next, calculate the number of trees in a large forest.

10³ = 1,000

5 x 1,000 = 5,000

a large forest will have about 5,000 trees.

last, multiply the number of leaves per tree by the number of trees to get the number of leaves that grow on the trees in the forest during the lifespan of the trees.

200,000 x 5,000 = 1,000,000,000

there will be approximately 1,000,000,000 leaves on the trees in the forest during their lifespans.
