The ample availability of heat and moisture and the great distance from the sunlit canopy describe why rainforest trees have smooth, thin bark. Rough, thick bark manages heat loss and moisture evaporation and nurtures growth of lichens, mosses and orchids. Smooth, thin bark prevents growth that competes with the higher-growing branches and upturned foliage on rainforest trees that require greater vertical distances to reach life-sustaining sun.

Which trees have more of their trunks without branches those along the Forrest edge or deep in the woodlands why?
Depending on the density and the specific species, trees further inside of the stand will have fewer branches. The branches support the leaves, which is where the tree produces its food but require large amounts of water. As density increases shading reduces the efficiency of the leaves. At some point the leaves produce less food and consume more water than the tree can afford. The supporting tissues in the branch also require nutrients for cellular activity, so the tree cuts its losses by allowing the branch to die. This causes the crown (the live leaf area of the tree) to recede and can reduce the overall vigor and growth. This is much more prevalent in shade-intolerant species such as ponderoas pine. Shade tolerant species, such as Douglas-fir, grow much slower and can survive with more crown area and less available light. For that reason, trees on the edge of the stand more will have fuller, longer crowns (more branches lower on the trunk).
What is the major artery that supplies blood to the lower part of the leg the calf?
The major artery that supplies blood to the lower part of the leg, including the calf, is the posterior tibial artery. It runs along the back of the leg and divides into smaller branches that provide oxygenated blood to the calf muscles and other structures in the lower leg.
Can you show me the location and pathway of the sciatic nerve in the human body?
The sciatic nerve is the largest nerve in the human body and runs from the lower back down through the buttocks and into the legs. It branches off from the lower spine and travels down the back of each leg, providing sensation and muscle control.
How do trees grow branches?
Trees grow branches through a process called apical dominance, where the terminal bud at the top of the tree releases hormones that inhibit the growth of lateral buds lower down the tree. When the terminal bud is damaged or removed, the inhibition is lifted, allowing lateral buds to grow into branches. Branch growth is also influenced by environmental conditions, genetics, and the tree's overall health.
Knee flexion is when the knee is bent?
Yes, and knee extension would be when the knee is straight.
Why do trees in tropical rainforests have tall straight trunks?
Tree trunks are straight and branchless Tree trunks are straight and branchless in the rainforest because, so that they can grow tall. As their efforts can be on growing tall not having branches near the bottom. More water falls down on the top of the tree. Therefore,they put their efforts in growing tall so that gain most water. Simply, the trees are close together and grow towards the light only the tops receive light so the lower branches die off because of lack of the aforesaid light. The water supply to the trees is drawn up by the roots.
Are tree trunks straight and branchless?
Tree trunks are straight and branchless in their lower parts in their efforts to grow tall.
Why do straight branchless trunks develop like this?
Tree trunks are straight and branchless in their lower parts in their efforts to grow tall.
Why are the tall trees branchless?
Tree trunks are not branchless. The branches protrude from above the trunk. A tree with branches from ground level is called a shrub.
Why does a typical rainforest tree have a straight trink and few lower branches?
because it needs to get to the sunlight and not waist energy on building wide. It just needs the SUN
Why are the lower branches of my spruce tree dead?
The lower branches of your spruce tree may be dead due to lack of sunlight reaching them. As the tree grows taller, the upper branches block sunlight from reaching the lower branches, causing them to die off. This is a natural process known as self-pruning.
Where do spider monkeys live in the rainforest?
Spider MonkeysYes, spider monkeys do live, in tropical rainforests. Thay is the main place where they live. They do live in other rainforests, but mainly only a tropical rainforest.
Why are the lower tree branches most susceptible to damage from low temperatures?
Lower tree branches are more susceptible to damage from low temperatures because cold air is denser near the ground, causing it to settle around the lower part of the tree. Additionally, cold air tends to drain downward, leading to greater exposure of the lower branches to freezing temperatures. These factors can result in frost damage or freezing of the lower branches.
Should a newly planted tree have the lower branches cut to encourage faster growth?
Should a newly planted tree have the lower branches cut to encourage faster growth?
Judical branch role?
