Question

choose the best answer that contrasts how an oak tree and a squirrel obtain energy. the oak tree is a heterotroph that can obtain energy through photosynthesis or cellular respiration, and the squirrel is an autotroph that can only produce energy through cellular respiration. the oak tree is an autotroph that can obtain energy through photosynthesis or cellular respiration, and the squirrel is a heterotroph that can only produce energy through cellular respiration. the oak tree is a heterotroph that can obtain energy through photosynthesis or cellular respiration, and the squirrel is an autotroph that can only produce energy through photosynthesis. the oak tree absorbs water from its roots to obtain energy, and the squirrel obtains energy through eating nuts and seeds.

Explanation:

Autotrophs (like oak trees) make energy via photosynthesis; heterotrophs (like squirrels) get energy by consuming others. The oak tree as an autotroph using photosynthesis and the squirrel as a heterotroph using cellular respiration (to break down consumed food) correctly contrasts their energy acquisition.

Answer:

The oak tree is an autotroph that can obtain energy through photosynthesis or cellular respiration, and the squirrel is a heterotroph that can only produce energy through cellular respiration.
