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.

Where does tree sap go when the tree dies?
The sap, along with the rest of the tree, decomposes into the earth, and may also be consumed by animals, fungi, and plants.
Does the tropical rainforest have tall trees?
Yes, while the tropical rain forest has more types of trees than anywhere else in the world, there are actually three layers of canopy: see the link, please...
By what three processes does water rise from the roots to the top of a tree?
Water travels from the roots to the top of a tree by the combination of 3 processes.
One of these processes is "transpiration" which occurs when water vapor escapes from the stomata, or small openings on the lower surface of leaves. This creates a negative pressure near the top of the trees which results in a sucking action similar to what happens when one inhales through a straw.
A second factor is "root pressure" which is the movement of water from the soil into the roots by osmosis. This causes a positive pressure in the roots which helps to "push" water into the plant.
The third process is "capillary action" which is the upward movement of water in very, almost microscopically, thin tubes. The structures in plants that transport water are called xylem tubes and they have a very narrow diameter so capillary action will occur in them.
These three processes acting together allow water to move against gravity to travel from the roots to the tops of tall trees and plants.
By winter the oak tree loses all its leaves why does this stop the growth of the tree?
the soil temperature is too low and the tree goes dormant until spring
The inner band of light wood typically represents the tree's growth during the spring and early summer, when conditions are favorable for growth, while the outer band of dark wood signifies the growth during the late summer and fall, when growth slows down. Together, these bands form annual growth rings, which can indicate the age of the tree and provide insights into the environmental conditions it experienced during each growing season. The thickness and density of these rings can also reflect factors such as climate changes, water availability, and overall health of the tree.
When is the best time to plant shrubs in North Carolina?
It is best to plant any type of tree or shrub when it is dormant, but a bit before it will begin new growth in the spring. Here in south Louisiana, that is late January to early February. But you can plant most shrubs any time, if you commit to provide adequate water frequently if the weather is hot.
Are walnut trees toxic to lupines?

What are some types of orange trees?
The link below provides some information on the basic different types.
The tree trunk spiders are members of the tropical and semi-tropical Family Hersiliidae. There are about 150 species in this family. These spiders have two very prominent spinnerets that are almost as long as their entire abdomens. So they are also sometimes known as "two-tailed spiders." They range in size from about 10 mm (0.4 inch) to 18 mm (0.7 inch)long. Being very well camouflaged for life on the varicolored trunks of trees, they have an interesting way of capturing prey. Rather than making a web that captures prey directly, they lay a light coating of threads over an area of tree bark and wait hidden in plain sight for an insect to stray onto that patch. Once that occurs, they direct their spinnerets toward their prey and circle it all the while casting silk on it. When the hapless insect has been thoroughly immobilized they can bite it through its new shroud. Spiders that live in trees.
What is a deciduous tree also known as?
Most deciduous trees are angiosperms (flowering plants) and also called "broad leaf" trees, in comparison to the needles on conifers. There are, however, some deciduous conifers, such as the larch and tamarack.
Can willow trees reach the ground?
Well, the trunk of the willow clearly touches the ground ;)
but yes, willow tree branches can reach the ground, and old willows' branches often do.
How tall is the Christmas tree in Cheshire Oaks?
the Cheshire oaks tree is 100 ft (30 metres) it's nickname is ''britain's tallest Christmas tree''
Why does holly leaves have less prickles the higher up the tree you go?
Prickles on the bush are there to prevent herbivores from eating the leaf.
And so as you go up the tree there are less herbivores grazing the leaves so the tree needs less prickles to prevent themselves being eaten.
This is the reason why there are less prickes higher up the tree you go.
What might occur in moth population if the color of the tree bark returned to its natural color?
Those whose color was similar to that of the color of the bark would be more likely to survive because of their new camoflauge. They are more likely to survive because of hiding from predators, and the population will swing back towards the camoflauge similar to the bark of the tree (natural selection)
What are names of trees that keep their leaves in the summer?
Trees that keep their leaves in summer and lose them in autumn are deciduous.
How do you take cuttings of a smoke tree?
To take cuttings of a smoke tree, first wait until the summer months before damaging the bark of the tree. Then, cut sections of the bark and branches that are about four to six inches in length.
Do you need a permit to trim trees?
Different jurisdictions might have special bylaws but generally you only need a permit to completely remove a tree.
Does horse urine or manure kill pine trees?
Horse urine or manure does not kill pine trees. The urine should be diluted because salts can accumulate in the soil which is not good for the pine.
