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.

  1. Recycling

  2. Composting

  3. Upcycling

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

Recycling involves processing waste or by-products to create new materials or products that can be used again.

Multiple choice

What is the term used to describe the process of breaking down footwear materials into smaller components for recycling or reuse?

  1. Degradation

  2. Decomposition

  3. Depolymerization

  4. Disintegration
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Depolymerization is the process of breaking down polymers, the building blocks of synthetic materials, into their smaller units, enabling recycling and reuse.

Multiple choice

What is the term used to describe the process of capturing and storing carbon dioxide from the atmosphere?

  1. Carbon Sequestration

  2. Carbon Capture and Storage

  3. Carbon Mitigation

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

Carbon capture and storage (CCS) is the process of capturing carbon dioxide from industrial sources and storing it underground or in geological formations to prevent its release into the atmosphere.

Multiple choice

  1. Pre-Consumer Food Waste

  2. Post-Consumer Food Waste

  3. Consumer Food Waste

  4. Industrial Food Waste
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pre-consumer food waste refers to food waste that occurs before food reaches the consumer, during production, processing, and distribution.

Multiple choice

Which method involves converting food waste into biogas through a biological process?

  1. Composting

  2. Anaerobic Digestion

  3. Incineration

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

Anaerobic digestion is a process that converts organic matter, including food waste, into biogas through the action of microorganisms in the absence of oxygen.
