Question

wild fluctuations in their population size above and below carrying capacity. r - selected species have a generalized niche and rely on sheer numbers for survival. an example of an r - selected species are cockroaches. what happens to the offspring of most r - selected species in terms of offspring survival? they all have a very low reproductive rate. the majority dont even survive to adulthood. they have few offspring with great parents. most of the few offspring reach adulthood.

Explanation:

R - selected species rely on sheer numbers for survival. They produce a large number of offspring. However, due to factors such as limited resources, high competition, and a generalized niche (not well - adapted to specific stable conditions), the majority of their offspring do not survive to adulthood. This is in contrast to K - selected species which have fewer offspring but with more parental care and a higher survival rate of offspring.

Answer:

B. The majority don't even survive to adulthood.
