Which of the following is an abiotic population control mechanism?Multiple Choicepredationdiseasewater shortagesprey shortagescompetition

1. Break Down the Problem

The question requires identifying which option is an abiotic (non-living) population control mechanism from a list that includes biotic (living) factors.

2. Relevant Concepts

• Abiotic factors: These are non-living physical and chemical elements in the environment. Examples include temperature, water, and nutrients.
• Biotic factors: These involve living components that can affect populations, such as predation, disease, and competition.

3. Analysis and Detail

• Predation: A biotic factor where one organism preys on another.
• Disease: Also a biotic factor, as it relates to living organisms affecting others.
• Water shortages: An abiotic factor, as it is a non-living element affecting populations.
• Prey shortages: This is a biotic factor involving living organisms (the prey).
• Competition: This is a biotic factor where organisms compete for resources.

4. Verify and Summarize

Among the options provided, water shortages is the only abiotic control mechanism, as it involves a non-living factor affecting population dynamics.

Final Answer

Water shortages is the abiotic population control mechanism.
