What are the primary ways dissolved oxygen is lost from an aquatic ecosystem?
- Through respiration by aquatic organisms.
- Through the air-water interface.
- Through photosynthesis by aquatic plants.
- Through absorption by the substrate at the bottom of the water body.
How does turbidity affect aquatic ecosystems?
- It increases the penetration of sunlight, enhancing photosynthesis.
- It reduces the extent of light penetration, thereby limiting photosynthetic activity.
- It has no significant impact on light penetration or photosynthesis.
- It is caused by dissolved gases and does not involve suspended particles.
What defines the photic zone in an aquatic ecosystem?
- The region where light penetrates sufficiently for photosynthesis to occur.
- The deepest part of the water body where no light reaches.
- The layer of water where temperature is consistently low.
- The area where dissolved oxygen levels are at their highest.
Which of the following are the major limiting factors for the productivity of aquatic ecosystems?
- Sunlight
- Temperature
- Wind speed
- Atmospheric pressure

- The size of Nekton ranges from tiny swimming insects to the largest marine mammals like the blue whale.
Which statements correctly characterize Plankton?
- Plankton possess strong swimming abilities to counteract water currents.
- This group includes both microscopic plants (phytoplankton) and animals (zooplankton).

- Periphyton are exclusively microscopic organisms.
Which of the following statements accurately describe Neuston organisms?
- Neuston are organisms that live attached to submerged surfaces.
- These organisms reside at the air-water interface, such as floating plants and certain animals.
- Water striders are an example of Neuston that spend most of their lives on top of the air-water interface.
- Neuston obtain all their nutrients and sustenance directly from the air.
Which of the following statements accurately describes salinisation?
- Salinisation is the process where the salt concentration in the soil increases.
- High evaporation rates can contribute to salinisation.
- Salinisation is a concern in areas with low evaporation rates.
- Salinisation is synonymous with soil salinity.
What is salinisation?
- Salinity refers to the salt content of the soil.

- A reduction in productivity between 10% and 25% is considered severe desertification.
- Desertification is classified as moderate if productivity reduction is between 10% and 25%.
- A productivity reduction exceeding 50% is termed very severe desertification.
- Severe desertification occurs when productivity decreases by more than 50%.
