Insolation is the amount of solar energy that is incident on the surface of the earth. For the same insolation, water bodies tend to absorb the most heat as water has a high heat capacity and so do grasslands. Areas such as desserts and glaciers do not absorb high amounts of insolation due to which these areas exhibit extreme, inhabitable environments. The order becomes:
The Atlantic Ocean
A marshy wetland
Nevada desert
Polar ice caps
First, we need to solve for the common ratio from the data given by using the equation.
a(n) = a(1) r^(n-1)
1024 = 4 r^(9-1)
256 = r^8
r = 256^(1/8)
r = 2
Then, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(9) = 4 (1 - 2^9) / 1-2
S(9) = 2044
Therefore, the correct answer from the choices listed above is option B.
Answer:
Ecological footprint estimates the requirements of renewable resources that a population consumes to live a particular lifestyle. Some ecologists are concerned because the result of the ecological footprint shows that the demand of the population is increasing in comparison to the supply of nature.
For example in India, the ecological footprint shows negative impact of population demand over supply of nature.
The growth of the population is described below.
<h3><u>Explanation</u>:</h3>
The population growth of the region is varying according to many factors like,
A. Members of the reproductive age group.
B. Availability of nutrition.
C. Mortality rate of the population.
Here the members of the reproductive age group are few. The population being small in a large area there is a high availability of nutrients.
So the growth rate of the population will be very high. This is called the log phase of the growth.
Then comes the lag phase of growth where the population is considerably big with a fight for food and shelter. The survival of the fittest is seen and the population still grows but slowly. This is the lag phase.
But with time, the population growth is stopped because the ecosystem has a particular carrying capacity which is the maximum number of population that the ecosystem can support. So beyond this, the population won't increase, and thereby the natality rate and the mortality rate becomes equal.
