Multiple choice

The process by which marine organisms remove carbon dioxide from the atmosphere and convert it into organic matter is known as:

  1. Photosynthesis

  2. Respiration

  3. Decomposition

  4. Fermentation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photosynthesis is the process by which marine organisms, primarily phytoplankton, use sunlight, carbon dioxide, and water to produce organic matter and oxygen. This process plays a crucial role in the cycling of carbon and oxygen in the ocean and atmosphere.

Multiple choice

The process by which marine organisms break down organic matter into simpler substances is known as:

  1. Decomposition

  2. Photosynthesis

  3. Respiration

  4. Fermentation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Decomposition is the process by which marine organisms, such as bacteria and fungi, break down organic matter into simpler substances, such as carbon dioxide, water, and nutrients. This process plays a crucial role in the cycling of nutrients in the ocean.
