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.

- Did you know?
Insects are more likely to asexually reproduce than animals?
FACTS.(20 votes)- Yes, some insects do reproduce asexually, but remember that insects are a type of animal, too!(30 votes)
- Do male birds always attract female birds like this or is there some other way?(12 votes)
- Not always.
When it comes to birds, the male usually attracts the female. This can be done through attractive looks, flying, fighting, and, of course, offerings.(16 votes)
- how on earth does asexual reproduction work? is it for the organisms that don't require a mate to produce offspring?(10 votes)
- Yes, they don't require a mate, but it's kinda like cell division, to be honest.(12 votes)
- can someone explain to me in the easiest way on what offspring reproduction means?(5 votes)
- The more babies (that actually survive birth and childhood),the higher the reproductive success.(5 votes)
- Some behaviors increase the chance of producing offspring. These include displays that attract mates.(10 votes)
- 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.(6 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.(13 votes)
