Why do trees in the rainforest's have straight trunks and few lower branches?
Wiki User

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.

∙ 11y agothey have straight trunks because competition from surrounding vegetation and lack of light forces it to grow straight up. i dont know why it has few lower branches though
Wiki User
∙ 12y agobecause of the lack of light that gets to the bottom of the tree, no branches have the opportunity to grow x

∙ 13y agoThe trees are trying to fight for as much sunlight as they can get. So they are growing for the sunlight!

What is the major artery that supplies blood to the lower part of the leg the calf?
It is called the femoral artery that branches out into 2 tibial arteries and one peroneal artery.
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).

How do I trace blood from the ascending aorta to the lower right first molar?
The first thing is to determine what artery provides blood to the lower right first molar. The lower teeth sit in the mandible and are supplied by branches of the The major artery in the mandible supplying the teeth is the inferior alveolar artery, which sends branches to supply the roots of each tooth (including the first molar) in the lower jaw. Next is to find the origin of the inferior alveolar artery and work backwards until we get to the ascending aorta. The inferior alveolar artery is a branch of the internal maxillary artery, which itself is a branch of the external carotid artery. The external carotid artery is a branch of the common carotid artery. So far everything has been symmetrical, so it hasn't mattered whether we specified that the artery was on the right or the left side. But the common carotid arteries behave a little differently. The right common carotid is a branch of the innominate artery, which branches from the aortic arch. The left common carotid artery branches directly from the aortic arch. Since we're concerned with the lower right first molar, we'll work backwards from the right common carotid, innominate artery, and aortic arch. The last bit is just to know that the aortic arch is an extension of the ascending aorta. With that, we're done. Now we just sew the whole thing together, artery by artery, in the reverse order: Ascending aorta -> aortic arch -> innominate artery -> right common carotid artery -> right external carotid artery -> right internal maxillary artery -> right inferior alveolar artery -> branch to lower right first molar.
Which is the longest cranial nerve in human body?
Fifth, or trifacial, or trigeminal, is the largest cranial nerve It has three divisions : (1) The ophthalmic, which leaves th6 cranium through the sphenoidal fissure, and sends branches to the skin of the forehead, the lachrymal gland, the eye, and the nose (sensory). (2) The superior maxillary leaves the cranium by the foramen rotundum ; it supplies the skin of the temple, cheek, nose, upper lip, upper teeth, and the mucous lining of the mouth and pharynx (sensory). (3) The inferior maxillary leaves the cranium through the foramen ovale ; it gives branches to the temple and external ear, the teeth, and lower jaw, and supplies the tongue with a nerve of taste (motor and sensory).
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 can't tillandsia plants grow well on the lower branches of trees?
they can't grow on low branches of trees because they are found in rain forests and rain forests are full of shade and tillandsias need light from the sun to create nutrition from photosynthesis. on lower branches they don't have the light because higher branches are in the way.
