because if they had a few giant leaves they would die too quickly.The reason they would is because in the fall the leaves wilt and drop off the tree, and the only thing that can feed the tree is it's leaves. And since there would be only a few leaves, the tree would die too quickly before it can grow more.That's why they have many small leaves instead.

1: if the tree had big leaves, it would take up alot of water,
2: If the leaves never fell off the tree, then in the winter if snow falls on the leaves, the branches wouldn't be able to support all the snow and snap
3: If the leaves never fell off the tree and there was a wind storm, the force of the wind would be so strong, that the leaves would uproot the tree.

Leaves are used to collect light so the more shade the tree grows in the bigger the leaves, this applies to trees in their native situation.

Why do some plants have small leaves and some have big leaves thank you?

because they just do Plants with small leaves live in extreme environments. Some plants have big leaves to make photosynthesis easier for the plant probably because it lives somewhere shady. Plants with small leaves have lots of light so big leaves are not required. The bigger the leaf the bigger the surface area so big and small leaves collect the same amount of light. **Edit** Additionally a big factor that stresses effective leaf sizing is the amount of atmospheric moisture and heat. Some plants will fix carbon in the night time, reducing the amount of water loss they experience through the stomata, but others do not: as they intake CO2, they also lose water due to the heat. Hence a cactus's leaves are thin needles. Doesn't allow for a lot of CO2 fixation (so slow growth), but there's very little evaporation, so they don't die easily. It's a tradeoff for many plants.
