  2. Photosynthesis

  3. Respiration

  4. Decomposition

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Decomposition is the process by which marine organisms convert organic matter into carbon dioxide. During decomposition, microorganisms break down organic matter, releasing carbon dioxide as a byproduct. Decomposition contributes to the global carbon cycle and influences the balance of carbon dioxide in the atmosphere.

What is the term used to describe the process by which marine organisms convert organic matter into inorganic compounds?

  1. Carbon sequestration

  2. Photosynthesis

  3. Respiration

  4. Decomposition

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Decomposition is the process by which marine organisms convert organic matter into inorganic compounds. During decomposition, microorganisms break down organic matter, releasing inorganic compounds such as carbon dioxide, water, and nutrients. Decomposition contributes to the global carbon cycle and influences the balance of carbon dioxide in the atmosphere.

  1. Decomposition

  2. Nitrification

  3. Denitrification

  4. Photosynthesis

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 compounds, releasing nutrients back into the ecosystem.

Multiple choice

What is the scientific term for the process of converting fat into smaller molecules?

  1. Lipolysis

  2. Hydrolysis

  3. Polymerization

  4. Oxidation

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Lipolysis is the process of breaking down fat into smaller molecules, such as fatty acids and glycerol. This process occurs during digestion and is catalyzed by enzymes called lipases.

Multiple choice

What is the term for the process of removing the feathers from a slaughtered poultry bird?

  1. Scalding

  2. Picking

  3. Evisceration

  4. Chilling

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Picking is the process of removing the feathers from a slaughtered poultry bird. This can be done manually or mechanically using specialized equipment. Scalding is a step that precedes picking and involves immersing the bird in hot water to loosen the feathers.
