Multiple choice

Which ecosystem service is responsible for the transfer of pollen from one flower to another, enabling fertilization and seed production?

  1. Pollination

  2. Decomposition

  3. Nutrient cycling

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

Pollination is the ecosystem service that involves the transfer of pollen from the male anther of a flower to the female stigma, facilitating fertilization and the production of seeds, which are essential for food production.

Multiple choice

Which ecosystem service is responsible for the decomposition of organic matter, releasing nutrients back into the soil?

  1. Decomposition

  2. Nutrient cycling

  3. Pollination

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

Decomposition is the ecosystem service that involves the breakdown of organic matter by microorganisms, releasing nutrients back into the soil, which are essential for plant growth and crop production.

Multiple choice

Which ecosystem service is responsible for the formation and maintenance of fertile soils?

  1. Soil formation

  2. Nutrient cycling

  3. Water purification

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

Soil formation is the ecosystem service that involves the physical, chemical, and biological processes that lead to the development of fertile soils, which are essential for crop growth and food production.

Multiple choice

Which of the following is an example of an in-situ soil remediation technique?

  1. Excavation and Disposal

  2. Pump-and-Treat

  3. Soil Vapor Extraction

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

Bioremediation is an in-situ technique that utilizes microorganisms to break down and degrade contaminants within the soil, converting them into harmless substances.

Multiple choice

Which of the following is a common type of ex-situ soil remediation technique?

  1. Landfarming

  2. Soil Washing

  3. Incineration

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

Landfarming is an ex-situ technique where contaminated soil is spread out in thin layers on a prepared land surface, allowing natural processes like biodegradation and volatilization to break down contaminants.

Multiple choice

  1. Compost

  2. Fertilizer

  3. Lime

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

Soil amendments such as compost, fertilizer, lime, and manure are commonly used to enhance soil fertility, improve soil structure, and adjust soil pH.
