Question

read the paragraph, then choose the word that best completes the sentence. hummingbirds use a lot of energy to hover while they extract the nectar from flowers. if a hummingbird spends several hours searching for food without success, it could starve to death purely because it takes so much energy to fly. hummingbirds have to save energy somewhere if they are to be able to get food. a hummingbird does this by entering a state called \torpor.\ when in this state, the hummingbirds body temperature falls nearly 50 degrees f (28 degrees c). its metabolic rate decreases by two - thirds the normal rate. though torpid hummingbirds use energy, the decreased usage helps them stay alive when food is scarce. torpor______energy. a conserves b neutralizes c disperses d obscures

Explanation:

The paragraph states that hummingbirds enter torpor to save energy. "Conserves" means to save or protect from harm, which fits the context. "Neutralizes" means to make ineffective, which is not relevant. "Disperses" means to spread out, which is the opposite of saving. "Obscures" means to make unclear, which also does not fit.

Answer:

A. conserves
