Primary succession occurs when pioneer species move into an area that has no plants. Which organisms are common pioneer species? Confer trees and tall grasses with roots that loosen the soil

Mosses and lichens that can grow on rocky surfaces

Grasses and weeds that arrive as seeds carried by the wind and then germinate in rich soil

Vines and shrubs that help prevent the erosion of shallow soil

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

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.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
