40 ! the survivorship curves of the american robin, a type of migratory songbird, and the common green darner, a type of migratory dragonfly, are shown below. what statement is best supported by the survivorship curves? a. american robins have a high survival rate for most of their lifespan and then decline rapidly in old age. b. american robins have similar death rates throughout their lifespan, while the death rate of common green darners changes over their lifespan. c. younger american robins have higher death rates than older american robins, while younger and older common green darners have similar death rates. d. a very high proportion of common green darners reach adulthood and live to older ages.

C.  

Younger American robins have higher death rates than older American robins, while younger and older common green darners have similar death rates.

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.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
