Question

chemosynthesis
definition: the process by which some organisms use chemical energy to produce carbohydrates.
characteristics
examples
non - examples

Explanation:

To fill in the "Examples" and "Non - Examples" for chemosynthesis:

Examples:

• Deep - sea vent bacteria: Bacteria like those in hydrothermal vents use hydrogen sulfide (a chemical compound) to perform chemosynthesis. They convert the chemical energy from the breakdown of hydrogen sulfide into carbohydrates, which serve as their food source.
• Nitrosomonas bacteria: These bacteria use the chemical energy from oxidizing ammonia to produce carbohydrates through chemosynthesis.

Non - Examples:

• Plants: Plants perform photosynthesis, which uses light energy (not chemical energy) to convert carbon dioxide and water into carbohydrates. So photosynthesis - based organisms like plants are non - examples of chemosynthesis.
• Animals: Animals obtain energy by consuming other organisms (either plants or other animals) and do not produce carbohydrates using chemical energy in the way chemosynthetic organisms do. For example, a lion gets energy by eating other animals, not by chemosynthesis.

Answer:

Examples:

• Deep - sea vent bacteria (use chemical energy from compounds like hydrogen sulfide to make carbohydrates).
• Nitrosomonas bacteria (use chemical energy from ammonia oxidation to produce carbohydrates).

Non - Examples:

• Plants (perform photosynthesis using light energy, not chemical energy for carbohydrate production).
• Animals (obtain energy by consuming other organisms, not by chemosynthesis).
