D. LONG ANSWER QUESTIONS

Ch-13 Population and Related Problems in India Goyal Brothers Prakashan ICSE Class-10 Biology Solutions

(Page-201)

Question 1. How is poverty related to population? Explain.

Answer : First, rapid population growth is likely to reduce per capita income growth and well-being, which tends to increase poverty. Second, in densely populated poor nations with pressure on land, rapid population growth increases landlessness and hence the incidence of poverty.

Question 2. List the advantages of having small families. What is meant by family welfare centres?

Answer : the top benefits of a small family.

Question 3. Give a brief of pressure of population on our natural resources.

Answer : It reduces the quality and quantity of natural resources through overexploitation, intensive farming and land fragmentation. Regions with high population pressure face scarcity of arable land, which leads to shortened/removed fallow period, declining soil fertility and farm income due to farm subdivision

Question 4. What is population explosion? How is it affecting the condition of people of a country?

Answer : Population explosion refers to the sudden and high increase in the growth of human population wherein the growth rate of population is higher than the rate of growth and development of a country. The basic reason that results in the population explosion is an increase in the survival rate

More people means an increased demand for food, water, housing, energy, healthcare, transportation, and more. And all that consumption contributes to ecological degradation, increased conflicts, and a higher risk of large-scale disasters like pandemics

Question 5. How can an educated person be benefitted by the family planning methods? Give a brief of a surgical method suitable for a man.

Answer : In countries with a moderate to strong family planning program, modest levels of education were associated with substantially lower fertility, whereas in countries with weak or nonexistent family planning programs, fertility rates of women with a few years of education were often found to be higher than that of women .

Vasectomy is also known as “male sterilization.” A surgeon cuts and seals off the tubes that your sperm pass through to reach your testicles. It’s the most effective birth control option for men. Only about 15 out of 10,000 couples get pregnant in the year after a man has the surgery.
