Answer:
The correct answer is c) logistic
Explanation:
Logistic growth occurs during a population growth when the resources are limiting. During logistic growth sigmoid (S-shaped) growth curve is produced when population size is placed over time.
In logistic growth first the population increases slowly then after some time it increase on the logarithmic phase until it levels off near the maximum carrying capacity due to environmental resistance. Beyond this maximum carrying capacity growth rate does not increase and becomes constant.
This generates an s-shaped curve called a sigmoid curve which shows the logistic growth. So the correct answer is c.
Answer:
the conclusive evidence about CFCs (chlorofluorocarbons) and the ozone layer of the earth.
Explanation:
Susan Solomon, Web of Science article reveals the conclusive evidence that CFCs (chlorofluorocarbons) could be destroying the protective layer of ozone in the earth’s upper atmosphere. CFCs are compounds that have the potential to destroy the protective layer of ozone (an oxygen compound) in the earth’s upper atmosphere.
Only about 3 percent of the worlds water is fresh, and even less than that is usable, because most of it is locked up in glaciers or in permanent snow fields.
