Explanation:
As an ecosystem changes,older inhabitants gradually die out and new organisms move in,causing further changes in the community.This series of predictable changes that occurs in a community over time is called ecological succession.Ecological succession is slow and gradual ;it occurs over a period of many years.
I hope this helps!
Like you stated, the water cycle is a closed sytem.Therefore, it's never ending it will keep on going, and repating it's self forever.So we need to keep it clean because, we use water for food, dishes, etc which is a pro.The con of trying to keep water is fresh is the fact we bathe, and clean with water. Even though we bathe, and stuff with water we can try to keep water clean.Even though water goes through a process and people say the water system cleans water doesn't mean it's true.The best ting we can do to keep free from population is use less water, and try keeping large, small bodies of water clean.
I believe the only reason why they could have survived
successfully despite living only on the same tree and they are large in number
is because:
“They feed on different parts
of the same trees.”
<span>So this means that although they are
many of them feeding on the tree, there is no food deficiency occurring since
they are getting their source of food from different parts of the tree anyway.</span>
It can be changed by currents
