Question

What are some advantages of internal compared with external fertilization?

a) Increased parental care.
b) Higher offspring survival rate.
c) Greater number of offspring.
d) Less energy investment.

Answer 1

Internal fertilization has advantages such as increased parental care, higher offspring survival rate, and a greater number of offspring.

Step-by-step explanation:

Internal fertilization has several advantages over external fertilization:

1. Increased parental care: In internal fertilization, the parents invest more time and effort in protecting and nourishing the developing embryo, increasing the chances of survival.
2. Higher offspring survival rate: Internal fertilization reduces the risk of predation and provides a stable environment for the embryo, resulting in a higher survival rate.
3. Greater number of offspring: Although internal fertilization generally produces fewer offspring compared to external fertilization, each offspring has a higher chance of survival, leading to overall greater reproductive success.
