An ecological pyramid illustrates the amount of energy at each trophic level. a biomass pyramid differs by showing what at each trophic level

It shows a diagrammatic representation of biomass at different tropic levels in an ecosystem

Explanation:

Goat eat grass. The goat are in turn eaten by the Man. The grass has the greatest biomass in this chain. Its biomass, therefore, sits at the bottom of the pyramid. Conversely, the man has the lowest biomass in the chain and hence sits on top of the pyramid.

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.

c. is the correct answer
