Students have asked these similar questions
Why is long-term parental care not associated with having many offspring during a reproductive episode?
Why would predation on small individuals lead to a population with delayed sexual maturity?
Group of answer choices
The delay reduces the likelihood of senescence
The delay leads to higher fecundiy
The delay allows more resources to be devoted into growing to a larger size that is less likely to be eaten
The delay increases experience and improves parental care
In an iteroparous species lifetime fitness is maximized at
investment, while in semelparous species
