Natural regeneration of forests and woodlands is the process by which new trees grow from seeds that have fallen and germinate where they have fallen. The biggest problem with natural regeneration is that is unpredictable. As a result, it cannot be used for commercial farming. For most of the last two or three hundred years, forests and woodlands have restocked by using transplants grown in nurseries. The young trees are planted in equidistant rows. This allows each tree the best possible change of optimal growth.
Answer:
(4) As time increased, distance remained
the same
Explanation:
The graph shows that the student measures equal distance everyday from the bridge to the rock for 7 days.
Everyday has an equal distance measured by the student all through the week.
Let's say the point on the vertical axis which represents distance measured is about 1.5 meters. It means that, for day 1, he measures 1.5 meters, day 2, he measured 1.5 meters, by day 3 another 1.5 meters. Same he does for 7 days. For the first 3 days, he would have measured 1.5 m × 3 = 4.5 meters.
This means that, as time (days) increased, distance measured each day remains the same.

Answer:
a. commensalism is the correct answer.
Explanation:
By growing on the trunk or branch of a tree, a lichen gains height and exposure to sunlight for photosynthesis. The tree is not harmed by the lichen but does not benefit either. The relationship between the lichen and the tree is commensalism.
Commensalism is a relationship between two organisms where one organism gets benefits from other organisms without causing any harm or any damage from the relation as it one side symbiotic relation.
In this, we can see lichen is getting benefits from the tree.
for example, lichen is getting following benefits from the tree such as ( a lichen gains height and exposure to sunlight for photosynthesis.) and they are causing any harm to tree neither any benefits so this is a one-side symbiotic relation and thus the relationship is an example of commensalism.
In the case of the large forest fire burns in Canada, the option that is known to be true is option B: . The Greenland glaciers will melt faster.
<h3>How do wildfires affect glaciers?</h3>
A new study has shown that the exposure of glaciers to any kinds of wildfire smoke can lead to the glaciers melting faster than normal.
Note that this often affects mountain runoff that gives the main freshwater resources for all of life downstream.
Hence, In the case of the large forest fire burns in Canada, the option that is known to be true is option B: . The Greenland glaciers will melt faster.
A large forest fire burns in Canada, dropping black carbon on Greenland. Which of the following is true?
A. The Greenland glaciers will be protected from melting as the ash will insulate the ice.
B. The Greenland glaciers will melt faster.
C. The black carbon will not affect the Greenland glaciers.
D. It is unknown as to what effect the black carbon would have on the Greenland glaciers.
