What is the term used to describe the process by which nutrients are released from dead organisms and returned to the environment?

  1. Decomposition

  2. Nutrient cycling

  3. Mineralization

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

Nutrient cycling refers to the process by which nutrients, such as nitrogen, phosphorus, and potassium, are released from dead organisms and organic matter through decomposition and then made available for uptake by other organisms in the ecosystem.

Multiple choice

  1. Decomposition

  2. Nutrient cycling

  3. Assimilation

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

Assimilation refers to the process by which nutrients, such as nitrogen, phosphorus, and potassium, are taken up by plants and other organisms from the environment and incorporated into their tissues.

  1. Decomposition

  2. Nutrient cycling

  3. Mineralization

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

Mineralization refers to the process by which nutrients, such as nitrogen, phosphorus, and potassium, are released from minerals and rocks through weathering and other processes, making them available for uptake by plants and other organisms.

Multiple choice

What is the term used to describe the process by which nutrients are lost from an ecosystem through processes such as leaching and erosion?

  1. Decomposition

  2. Nutrient cycling

  3. Assimilation

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

Nutrient loss refers to the process by which nutrients are lost from an ecosystem through processes such as leaching, erosion, and volatilization. Nutrient loss can occur naturally or be accelerated by human activities, such as agriculture and deforestation.
