Hibernation allows animals to conserve energy during periods of food scarcity or extreme weather conditions. By slowing down their metabolic rate, animals can survive on stored fat reserves for extended periods without needing to actively search for food. This reduces their energy expenditure and increases their chances of survival.
Additionally, hibernation can increase the chances of animals meeting a mate. Some species, such as bears, may briefly awaken from their hibernation state to reproduce. This allows them to reproduce during a specific time of the year when resources and environmental conditions are more favorable for the survival of their offspring.
Hibernation can also make access to food easier for animals. By going into a dormant state, animals can avoid competing with other species for limited food resources. They can wait until food becomes more abundant or easier to find before actively foraging again.
Furthermore, hibernation can protect animal young from predators. Many species that hibernate, such as chipmunks and ground squirrels, give birth while in their hibernation state. This allows them to protect their vulnerable offspring from predators, as they are less active and more concealed during this time. The sheltered and secluded environment created by hibernating can provide a safe place for young animals to grow and develop until conditions outside are more favorable for their survival.

Birds use courtship behaviors to attract a mate, which improves their reproductive success. Which courtship behavior also improves their chances of survival?
Responses
Male birds with bright colors have to preen frequently in order to maintain their feathers and keep pests away so they can attract mates.

A student is analyzing data that compare the change in the total number of wading bird nests in the Everglades to the change in rainfall. Wading birds feed primarily on fish. Fewer nests were observed in dry years than wet years.
What is a reasonable inference about the relationship between wading bird reproductive success and water depth in the Everglades?
Responses
Water depth does not affect wading birds’ access to food but does affect wading birds’ reproductive success
Water depth does not affect wading birds’ access to food but does affect wading birds’ reproductive success
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success
Water depth likely affects wading birds’ access to food, but this does not affect wading birds’ reproductive success.
