Which of the following is NOT a common source of soil contamination?

  1. Industrial waste

  2. Agricultural runoff

  3. Natural weathering

  4. Household chemicals


Correct Option: C
Explanation:

Natural weathering is a natural process that does not introduce contaminants into the soil.

How does soil contamination affect the ability of plants to absorb water and nutrients?

  1. It increases the availability of water and nutrients.

  2. It decreases the availability of water and nutrients.

  3. It has no effect on the availability of water and nutrients.

  4. It increases the availability of water but decreases the availability of nutrients.


Correct Option: B
Explanation:

Soil contamination can block the pores in the soil, making it difficult for water and nutrients to reach the plant roots.

Which of the following plant growth stages is most sensitive to soil contamination?

  1. Seed germination

  2. Vegetative growth

  3. Flowering

  4. Fruiting


Correct Option: A
Explanation:

Seed germination is the most sensitive plant growth stage to soil contamination because the seedlings are small and have a limited root system.

How does soil contamination affect the diversity of plant species in an ecosystem?

  1. It increases plant diversity.

  2. It decreases plant diversity.

  3. It has no effect on plant diversity.

  4. It increases the diversity of some plant species but decreases the diversity of others.


Correct Option: B
Explanation:

Soil contamination can reduce the number of plant species that are able to tolerate the contaminated conditions.

Which of the following animal groups is most likely to be affected by soil contamination?

  1. Birds

  2. Fish

  3. Mammals

  4. Insects


Correct Option: C
Explanation:

Mammals are more likely to be affected by soil contamination because they spend more time in contact with the soil and have a higher metabolic rate.

How does soil contamination affect the reproductive success of animals?

  1. It increases reproductive success.

  2. It decreases reproductive success.

  3. It has no effect on reproductive success.

  4. It increases the reproductive success of some animals but decreases the reproductive success of others.


Correct Option: B
Explanation:

Soil contamination can reduce the number of offspring that animals produce and can also increase the number of birth defects.

Which of the following animal behaviors is most likely to increase the risk of exposure to soil contamination?

  1. Feeding on soil-dwelling organisms

  2. Grooming fur or feathers

  3. Digging burrows

  4. Building nests on the ground


Correct Option: A
Explanation:

Feeding on soil-dwelling organisms is the most likely animal behavior to increase the risk of exposure to soil contamination because these organisms can accumulate contaminants in their tissues.

How does soil contamination affect the ability of animals to avoid predators?

  1. It increases the ability of animals to avoid predators.

  2. It decreases the ability of animals to avoid predators.

  3. It has no effect on the ability of animals to avoid predators.

  4. It increases the ability of some animals to avoid predators but decreases the ability of others to avoid predators.


Correct Option: B
Explanation:

Soil contamination can reduce the ability of animals to detect predators and can also make them more vulnerable to attack.

Which of the following is NOT a potential consequence of soil contamination for human health?

  1. Increased risk of cancer

  2. Neurological disorders

  3. Immune system dysfunction

  4. Improved cardiovascular health


Correct Option: D
Explanation:

Soil contamination is not known to have any beneficial effects on human health.

What is the most effective way to reduce the risk of soil contamination?

  1. Reduce the use of pesticides and fertilizers.

  2. Properly dispose of hazardous waste.

  3. Increase the amount of vegetation in an area.

  4. All of the above.


Correct Option: D
Explanation:

All of the above actions can help to reduce the risk of soil contamination.
