If each breeding pair of elephants produces 6 offspring during a 90-year life span, in 750 years, a single pair of elephants will have given rise to a population of 19 million elephants. yet elephants have not overrun the planet. why? elephants have a niche that expands with the population elephants produce more offspring than will survive to maturity most elephants are kept in captivity (circus & zoo) and not allowed to reproduce individual elephants in a population exhibit no variation, reducing their reproductive success elephants have become geographically separated into separate species that cannot interbreed

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
