Question

1. compare and contrast describe two different parenting strategies that animals use and explain why they are both effective.

Explanation:

One parenting strategy is r - selection (e.g., many fish species). They produce a large number of offspring with little parental care. This is effective as, despite high mortality, a few offspring survive due to sheer numbers. Another is K - selection (e.g., elephants). They have few offspring but invest a lot in parental care. This ensures higher survival rates of each offspring through protection, teaching survival skills etc. Both strategies are effective as they are adapted to the species' ecological niches. r - selected species thrive in unstable environments where mass reproduction compensates for high mortality. K - selected species do well in stable environments where quality care for few offspring maximizes their survival and reproductive success.

Answer:

One strategy is r - selection (e.g., fish) with many offspring and little care, effective due to high offspring number compensating for mortality. Another is K - selection (e.g., elephants) with few offspring and high care, effective as it ensures high survival of each offspring. Both suit their ecological niches (unstable vs stable environments respectively).
