Natural channels. Natural channels are formed by fluvial process and are found across the Earth. These are mostly formed by flowing water from the hydrological cycle, though can also be formed by other fluids such as flowing lava can form lava channels.
Answer:
The following can be deduced from the life history of bark beetles;
* All bark beetles life stages are spent in the phloem, internal bark, and bark, aside from when grown-ups leave the tree they created in to travel to new host trees. Bark beetles feed on the phloem of their host trees during grown-up and larval stages.
* Many bark beetles travel toward debilitated host trees, be that as it may, during environmental conditions ideal for population improvement, populaces may develop quickly and effectively assault healthy trees.
Explanation:
Bark beetles determine their name since they live and create in the bark and wood of trees and bushes. Grown-ups unearth egg displays in living bark (phloem).
Bark beetles are the most dangerous creepy insects in western coniferous woodlands. It has been assessed that 90% of insects caused tree mortality and over 60% of the complete insect caused loss of wood development in the US is because of bark beetles.
Answer:
The stem, which has two parts. The inner tissue is known as the xylem. It moves water and minerals from the roots to the leaves. The outer tissue is the phloem , which transports food from the leaves to the rest of the plant through a process known as translocation
The stem of a plant has two parts, Xylem (inner tissue) and Phloem (the outer tissue).
Xylem moves water and minerals from the roots to the leaves, while Pholem transports food from the leaves to the rest of the plant.

Sir Charles Lyell, 1st Baronet, FRS (14 November 1797 – 22 February 1875) was a Scottish geologist who popularised the revolutionary work of James Hutton. He is best known as the author of Principles of Geology, which presented uniformitarianism–the idea that the Earth was shaped by the same scientific processes still in operation today–to the broad general public. Principles of Geology also challenged theories popularised by Georges Cuvier, which were the most accepted and circulated ideas about geology in Europe at the time.[1]
