The importance of trees
What we think trees do
Most people think that trees just supply us oxygen, give us shade, help make the earth beautiful, and supply us wood. Trees also do other things for us.
Coniferous Trees (Evergreens)
Coniferous trees grow upward that cause them to have a triangular shape, that helps the tree to be strong. They will grow and stay green year round. The seeds are the cones. The cone opens up and the seed falls out. There are over 500 species.
Using the process of photosynthesis a tree takes carbon dioxide from the air and then stores it as carbon. While doing that the tree releases oxygen.
Trees are used for food, shelter, and places for reproduction. Organisms use trees to nest, for rest, to hunt, and capture prey.
There are over 23,000 kinds of trees.
One tree can absorb as much carbon in a year as a car produces while driving 26,000 miles.
The roots have two main functions. They keep the tree stable and absorb water, minerals, and oxygen.
What trees really do
Keep our air clean
Improve water quality
Provide food and building materials
Reduce the amount of carbon dioxide
Help prevent erosion
The part of the tree thats above the trunk. Including the branches and the foliage
The apex of the trees crown
The slender offshoot of a tree root
Roots that are covered in small absorbent hairs the helps supple the tree with minerals and water
Deciduous trees will spread out as they grow causing them to be rounded. They will stop growing in the winter which causes them to lose there leafs. The seeds are protected by a shell or fruit.
The main part of the tree
Part of the trunk that's between the stump and the first lower limbs
offshoot the grow out of the tree trunk
The offshoot on a branch
Leaves on a tree
The trunk supports the crown and helps hold up the leaves to light so photosynthesis can occur.
Foliage (leafs) are responsible for the process of photosynthesis, respiration, and transpiration.
They also cycle water between the atmosphere and soil to maintain rainfall levels.
The leaves and also the branches help protect the underlying soil from erosion.
Well maintained trees can add property value by about 14%.
Trees supply us many products that can be sold like lumber, paper, and food. Also they provide us clothes, cosmetics and more.
If a birdhouse is hung on a tree branch. It does not move up the tree as the tree grows.
About one third of the United States is covered by forests.
A single tree can produce approximately 260 pounds of oxygen per year. which means two mature trees can supply enough oxygen to support a family of four.
As said before, trees supply oxygen. Without oxygen animals and humans could not live.
