Which statement about adaptations is correct as it pertains to the scientific theory of evolution?

• Adaptations, which are learned behaviors, allow organisms to learn how to survive in any environment and predict environmental changes in order to prevent extinction of the species.

• Adaptations, processes in which an organism physically changes its environment, provide a way for a species to decrease its numbers to prevent competition.

• Adaptations, processes in which a single surviving organism chooses to change its traits, allows a species to redevelop variability and to increase in numbers.

• Adaptations, which are beneficial genetic traits, are critical to the survival of a species by providing alternative ways to adjust to a changing environment and prevent extinction.

Organisms that eat cows do not obtain a great deal of energy from the cows. In fact, they get less energy than the cows obtain from the plants that they eat. Why is this true?

• Cows store all their energy in milk.

• Cows use energy for their own metabolism.

• Cows pass on most of the energy to their offspring.

• Cows release all of their energy as heat.

• precipitation.

• Temperature

• altitude

• A and B
