Final answer:
Animals that begin reproducing early prioritize producing more offspring, while animals that reproduce later invest more in parental care. Late reproduction also minimizes competition among offspring. Options A, B, and D.
Step-by-step explanation:
When it comes to the difference in evolutionary pressures experienced by animals that begin reproducing early and those that reproduce late in their lifecycle, there are a few key factors to consider:
1. Early reproduction favors more offspring over longer lifespans: Animals that reproduce early allocate their energy towards producing a larger number of offspring, but this comes at the expense of their growth and health. They prioritize passing on their genes to as many offspring as possible.
2. Late reproduction requires greater parental investment: On the other hand, animals that begin reproducing later in life have the opportunity to invest more time and energy into their offspring. They can provide better parental care and increase the chances of their offspring surviving and reproducing themselves.
3. Late reproduction minimizes competition among offspring: By reproducing later, animals have the advantage of reduced competition among their offspring. This increases the chances of each offspring surviving and passing on their genes.
Hence, the right answer is options A, B, and D.
