  1. Photosynthesis

  2. Chemosynthesis

  3. Respiration

  4. Decomposition
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Decomposition is the process by which marine organisms break down organic matter into simpler substances, including carbon dioxide. This process plays a crucial role in the cycling of carbon in marine ecosystems.

Multiple choice

What is the term used to describe the process by which marine organisms convert carbon dioxide into organic matter using chemical energy?

  1. Photosynthesis

  2. Chemosynthesis

  3. Respiration

  4. Decomposition
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Chemosynthesis is the process by which marine organisms, such as hydrothermal vent bacteria, use chemical energy to convert carbon dioxide and other inorganic compounds into organic matter. This process is important in deep-sea ecosystems where sunlight is not available for photosynthesis.
