Circumference is the measurement around the trunk of the tree. It is usually measured at breast height because trees flare out at the bottom at different rates based on soil conditions. The best way to measure this is with a ribbon or piece of rope. Diameter can be measured by dividing this number by pi or 3.1415
centimeters
Feet or metres would seem the most suitable.
Hold a yardstick perpendicular to the ground, and measure the shadow. Make a proportion, then measure the tree's shadow. Use the proportion to compute.
Insects are most likely to be found in Amber. Because amber is a fossilized gum. The insects are likely to get stuck with gum prior to the process of fossilization of gum into amber.
struct node { int payload; struct node *left, *right; }; int height(struct node *tree) { if (tree == NULL) return 0; return 1 + max (height (tree->left), height (tree->right)); }
The parallax method is a way of measuring distances of far-away objects. Astronomers use parallax to measure the distance to stars. Parallax is a measurement of the shift of a nearby object compared to distant objects when observed from two different positions. You can see this effect for yourself. Cover your right eye and look directly at something some distance away, like a tree or house. Hold your hand at arms' length and stick up one finger, and cover the tree with your finger. Now uncover your right eye and cover the left eye, WITHOUT moving your hand. Your finger is no longer covering the tree. The "parallax shift", the distance that your finger appeared to move (relative to the tree in the background) can be used to measure how far away things are. For nearby objects in the solar system - for example, a comet or an asteroid - two observatories can observe the same object at the same time, and measure the "parallax angle" between the comet and a distant star. Knowing how far apart the two observatories are will let you calculate the distance to the comet. For other "nearby" stars, we assume that the stars themselves aren't moving quickly. Take one measurement today, and another measurement exactly six months later. We know the distance between the two observations is 184 million miles (twice the Earth's orbital radius). If our reference star is far enough away, we can use the parallax angle to calculate the nearby star's distance. For VERY distant objects, this doesn't work, for two reasons. 1. The parallax angle is too tiny to be measured accurately 2. We cannot be sure that the reference star in the background is far enough away from the "nearby" star to accurately calculate the distance.

Your question presumes that tree trunks are all circular. If you happen to find a circular tree trunk, you would measure around it to find the circumference. If the tree trunk is not circular, you will not be able to find the circumference but, you can measure around it to determine its perimeter.
Tree trunks is that trees middle position.
tree trunks have xylem and phloem
Depends on how big the tree is. Not all trees measure the same.
A cloth tape / flexible measure.
Trunks
Lichen is a combination of fungus and algae. It grows on tree trunks.
A: Find the precise circumference of the trunk and divide by Pi. B: Cut the tree halfway through and stick a tape measure at the end of the cut (the middle of the tree) XD
A flexible tape measure is best. A string will do also. Just wrap the string around the tree until it doubles up on its self, then measure the string.
Algae or mosses live on tree trunks.
