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. A very high proportion of common green darners reach adulthood and live to older ages. B. Younger American robins have higher death rates than older American robins, while younger and older common green darners have similar death rates. C. American robins have a high survival rate for most of their lifespan and then decline rapidly in old age. D. American robins have similar death rates throughout their lifespan, while the death rate of common green darners changes over their lifespan.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

so both hydrogen and clorine are compounds
