Mention any four probable reasons for the rapid rise of population in our country?
Step by step
Solved in 2 steps
- Mention three main reasons for the sharp rsie in human population in the world.What factors led to the dramatic decrease in population growth rates in Kerala, India?Compare the case of Kerala to India’s national population control program put intoplace in the 1970s.How would you describe human population growth for the past 200 years. When determining Earth’s carrying capacity for humans, why is it not enough to just consider human numbers? What will happen if there is a rapid growth in human population? What solutions do you have in mind to limit the human population growth?
- Give three most important reasons for population explosion in India.Using the above graph, what is the approximate percent of the population in the US and Kenya that is under the age of 15? (number order represents US, Kenya) A24,26 B12,28 C32,62 D16,36Figure 45.16 Age structure diagrams for rapidly growing, slow growing, and stable populations are shown in stages 1 through 3. What type of population change do you think stage 4 represents?
- Japan currently exhibits which of the following age-structures (population profiles)? A. the column population profile B. the inverted pyramid population profile C. the bulge population profile D. the pyramid population profile E. all of the aboveWhat would happen to the moose population if the wolves were removed from the island? What happens to the population of wolf if the moose population will decrease? Identify 2 possible limiting factors that have influenced the wolf population?Populous nations such as China have instituted strict policies tocurb population growth. In 1979, China implemented a “one-child”policy.Do you think that such strict control methods are appropriatefor population control?
- What are the two key concepts for this section? Listthree variables that affect the growth and decline ofhuman populations. How can we calculate the population change of an area? Define the total fertilityrate (TFR). How has the global TFR changed since1955? Summarize the story of population growth inthe United States. List six changes in lifestyles thathave taken place in the United States during the 20thcentury, leading to a rise in per capita resource use.Why does the exponential model of population growth produce a curve shaped like a J?The per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates. See attached image If the death rate decreased, what would happen to the population trajectory for population A? a) increase faster b) increase slower c) decrease faster d) decrease slower
