increased birth rate

constant death rate

decreased birthrate

constant birth rate


3:as resources in a population become less available, the population

declines rapildy

increases slowly

reaches carrying capacity

enters a phase of exponetial growth



4:when the exponential phase of logistic growth curve of a popualtion ceases

the size of the population drops

the size of the population stays the same

population growth begins to slow down

population growth begins to speed up



5: which of the following is the most likely reason that a population of mice in a farming area suddenly increases

more mice immigrate from neighboring areas

fewer mice emigrate to neighboring areas

more food is availble as grain is harvested

more nesting space is availble as new

Answer 1

Answer:

1.) Decreased birthrate

2.) Exponential

3.) Reaches carrying capacity

4.) Population growth beings to slow down

5.) More food is available as grain is harvested

Answer 2

Answer:

1. The correct option is decreased birth rate.

3. The correct option is that the population would reach its carrying capacity.

4. The correct option is population growth begins to slow down.

5. The correct option is more food is available as grain is harvested.

Explanation:

1. The decreased birth rate would affect the growth rate in case immigration and emigration rates are the same. Immigration implies permanently moving to another country while emigration implies leaving one's nation to settle in another nation.

Decreased birth rate means less population is available for stimulating economic work. Thus, a large number of people would become older, which would ultimately impact economic activities and growth.

Therefore, an increased birthrate and constant birth rate or death rate would not slow down the economic growth rate.

3. The resource availability in an economy would affect its carrying capacity. It means if the population increases more and more compared to resources then it would not be able to support the ecosystem efficiently.

4. The exponential growth would end when there is a fall in the population rate decreases and carrying capacity is reached. Thus, it implies less availability of resources to meet the demands of population.

5. The availability of food increased with the harvesting of grains. Thus, it provided consumption and survival benefits to mice in farming areas.
