Questions: Which statement best describes how living things obtain energy? Some living things get the energy they need by consuming glucose, while others get the energy they need by consuming other organisms. All living things get the energy they need by consuming glucose. Some living things get the energy they need from the sun, while others get the energy they need from consuming other organisms. All living things get the energy they need by consuming other organisms.

The answer is the third one: Some living things get the energy they need from the sun, while others get the energy they need from consuming other organisms.

Explanation for each option:

1. Some living things get the energy they need by consuming glucose, while others get the energy they need by consuming other organisms.

   • This statement is partially correct but not comprehensive. While some organisms do consume glucose directly, it does not account for autotrophs like plants that produce glucose through photosynthesis.

2. All living things get the energy they need by consuming glucose.

   • This statement is incorrect. Not all living things consume glucose directly. Autotrophs, such as plants, obtain energy from sunlight and convert it into glucose through photosynthesis.

3. Some living things get the energy they need from the sun, while others get the energy they need from consuming other organisms.

   • This statement is correct. Autotrophs, like plants, algae, and some bacteria, obtain energy from the sun through photosynthesis. Heterotrophs, like animals and fungi, obtain energy by consuming other organisms.

4. All living things get the energy they need by consuming other organisms.

   • This statement is incorrect. Autotrophs do not consume other organisms for energy; they produce their own energy through photosynthesis or chemosynthesis.

In summary, the third statement accurately describes the two primary ways living things obtain energy: through photosynthesis (from the sun) and by consuming other organisms.
