Explain why survival and reproductive success may not be equal for all individuals in this population.

We show that in the stable population reproductive output is higher, and adult survival is lower; the difference in viability between the two populations is due to the difference in reproduction; reproductive rates are variable, whereas survival rates are relatively constant over time

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
