Question

Give the reasons : Deciduous trees have trucks with thick barks why ?

Answer 1

Hey mate!

Here's your answer!!
----------------------------
The trunks of deciduous trees develop what are called buttress roots to support the weight of the tree.

Tree bark is a defence against herbivores, insects and parasitic plants.

These kind of trees develop thicker bark when they live in fire prone areas.

Deciduous trees have no foliage, so that's why, it is the bark that becomes the foliage.

It also serves a purpose as it protects the tree, and provides the tree with the important nutrients and moisture it needs to grow.

This is why it is important to protect a trees bark by using tree guards, especially over the winter months when rodents are hidden under the snow and eat the bark of the tree.
