Behaviors Aid Reproduction Practice Test

A wildlife camera recorded wolves during spring, when pups are typically born. In one pack, adults were frequently observed bringing food back to a den site. In a nearby pack, this behavior was observed less often. Later, the number of pups surviving to 8 weeks was higher in the pack with more food deliveries to the den. Behaviors can affect reproductive outcomes.

Which prediction is supported if the food-delivery behavior decreases in a pack during the same season?​​

Behaviors can affect reproductive outcomes. A student makes four claims after watching a nature video recorded during salmon breeding season. The video shows male salmon defending a small area of the streambed where females later deposit eggs.

Which claim about reproduction is incorrect based on the behavior and evidence shown?
