Trees
Above ground, trees and shrubs perform important environmental services by providing food and shelter to people and wildlife, oxygenating the air, and beautifying the landscape. Below ground, their roots open up critical passageways for the movement of air, moisture, and soil food web members.

Trees are cut down and then cut into logs of desired lengths. The logs are trucked to a sawmill where they are cut into lumber of desired thicknesses. The lumber may be planed to make it smoother. It is then either purchased planed or unplaned from the sawmill or trucked to stores, like Lowe's and Home Depot, where it is purchased by a consumer.
How much CO2 do trees produce at night?
no, not at all. albeit amount of released oxygen can reach lower or even lowest but can't produce CO2.
You can build most of the furniture you see in project books, etc. with pine if you are not fussy about the finish. Will it last? We own pine furniture built up to 300 years ago. It does not look bright and shiny anymore, but it looks fine if you are into real Colonial look.
Why do some trees have small leaves and others have large leaves?
In nature small leaved trees usually have access to plenty of light.
Large
leaved trees usually have to compete for available light.
What kind of plants are on the mountain K2?
There are many kinds of plants that grow on mountain K2. Some of these include poplars, willows, walnuts, blue pines, deodars, feet birch, and elms.
Yes.
In a tree, 'breathing' takes place in the leaf. Chlorophyll (the substance causing the green colour) absorbs the CO2 and uses it along with water to dissolve minerals taken up through the roots. After the chemical reaction is completed, the leaf releases oxygen and water vapor through its pores.
A hard heavy wood usually black that was traded in ancient Africa?
Ebony. Species of ebony include Diospyros ebenum (Ceylon ebony), native to southern India and Sri Lanka; Diospyros crassiflora (Gabon ebony), native to western Africa; and Diospyros celebica (Makassar ebony), native to Indonesia and prized for its luxuriant, multi-colored wood grain. Mauritius ebony, Diospyros tesselaria, was largely exploited by the Dutch in the 17th century. Some species in the genus Diospyros yield an ebony with similar physical properties, but striped rather than evenly black (Diospyros ebenum).

Do evergreen trees lose their leaves in the winter?
yes No, but I will explain. All green things have a growing season. That's why the corn in the field dies and the oak trees' leaves fall off. The usual ideas about cold weather or shorter days are bogus. You can fool plants into lengthening their growing season, but not by much! So just the same as evergreens know when to shoot out new growth and when to drop pine cones, they shed needles too. And I hope you didn't mean Christmas trees......
A cork is seal for a bottle. Traditionally, corks were made out of a type of aged wood. Nowadays, most corks are made out of plastic, though wooden corks are still used for higher end wines. The verb form of cork means to close or sealsomething. The idiom, put a cork in it, means to stop speaking.
Cork is the buoyant, light brown substance obtained from the outer bark layer of the cork oak. It is used to seal bottles.
yes.
Strictly speaking the leaves or needles do not survive forever but live and drop thro out the year so althought the tree appears to be evergreen it simply always has most of it's leaves or needles on all year.
What is the scientific name for the White Meranti tree?

What burns faster soft or hard wood?
Normally soft wood would burn fastest. It actually depends on the density of the wood and the amount of pitch or sap still held by the wood. For instance, soft woods such as pin and cedar, when very dry, burn very fast. However, English brown oak, a hard wood will burn as fast or faster than pine. Balsa, also technically a hardwood, burns very fast. The denser the wood, the slower the burn.
