Lesson 2: Animal behavior and offspring successAnimal behavior and offspring success
Review your understanding of animal behavior and offspring success in this free article aligned to NGSS standards.
Key points:
- Many animals use sexual reproduction to have offspring. To do this, an animal typically mates with an individual of the opposite sex. Mating results in fertilization, and the production of offspring.
- An animal’s reproductive success is related to the number of offspring it has during its life. An animal that has more surviving offspring likely has a higher reproductive success.
- Animals carry out certain behaviors to increase their reproductive success.
- Some behaviors increase the chance of producing offspring. These include displays that attract mates.
- Other behaviors increase the chance that offspring will survive and be able to reproduce. These include protecting and feeding young offspring.

- Why don't all species reproduce asexually? If they did, wouldn't it drive reproductive success? I'm asking this because if every animal reproduce asexually they wouldn't need to mate which would waste less time and energy.(5 votes)
- Sexual reproduction actually contributes genetic diversity to populations. When the different animals have different traits, it’s more likely that some of them will have traits that let them survive in changing environments.(5 votes)

- Why is this important?, it makes no sense(2 votes)
- Reproduction is important because that's how animals stop themselves from going extinct- if an animal has a high reprodictive success, it will have more surviving babies and keep the species alive for longer.(3 votes)
