A trait that helps an organism survive and reproduce is called an adaptation.

Here's why:

* Survival: Adaptations allow organisms to better cope with their environment, finding food, avoiding predators, and surviving harsh conditions.

* Reproduction: Adaptations can also help organisms attract mates, find suitable nesting sites, and care for their young, all of which are essential for successful reproduction.

Think of it this way: adaptations are the tools that help organisms succeed in the game of life!
