How is a pencil biologically different from a cat?

A cat has a biological/chemical makeup, via animal cells. While a pencil doesn’t have a biological makeup because it’s just graphite wood and rubber, while the cat is flesh skin and bone.

The given statement that deciduous trees lose their leaves each year is true.

These trees are most commonly found in tropical and temperate climates having broad leaves and a very high water requirement. As these trees require a lot of moisture because of the broad surface of leaves that causes a lot of water loss due to transpiration, the leaves are shed off during winter or dry seasons to minimise the water loss. Some common examples of deciduous trees are oak and maple.
