D Correct answer
Explanation

Limestone quarrying can have a significant visual impact, including the formation of unsightly scars, the loss of vegetation, and the disruption of wildlife habitats.

Multiple choice

What is the main cause of biodiversity loss?

  1. Habitat destruction

  2. Climate change

  3. Pollution

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

Habitat destruction is the main cause of biodiversity loss. When natural habitats are destroyed, the species that live in those habitats are at risk of extinction.

Multiple choice

Which of the following is a major threat to coastal ecosystems in India?

  1. Pollution

  2. Climate change

  3. Overfishing

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pollution, climate change, and overfishing are all major threats to coastal ecosystems in India.

Multiple choice

What are some threats to vernal pools?

  1. Habitat loss

  2. Pollution

  3. Climate change

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Vernal pools are threatened by a variety of factors, including habitat loss, pollution, and climate change. Habitat loss occurs when vernal pools are filled in or drained for development. Pollution can occur when chemicals or other pollutants are dumped into vernal pools. Climate change can cause vernal pools to dry out more frequently or for longer periods of time.

Multiple choice

What is the primary impact of marine pollution on marine ecosystems?

  1. Habitat destruction

  2. Loss of biodiversity

  3. Disruption of food chains

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Marine pollution can lead to habitat destruction, loss of biodiversity, disruption of food chains, and a range of other negative impacts on marine ecosystems.

Multiple choice

Which of the following is NOT a factor that contributes to the resistance of alpine ecosystems?

  1. High levels of endemism

  2. Low levels of biodiversity

  3. Harsh environmental conditions

  4. Long history of human disturbance
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A long history of human disturbance can reduce the resistance of alpine ecosystems to disturbances.

Multiple choice

How does high endemism contribute to the resistance of alpine ecosystems?

  1. It makes the ecosystem more vulnerable to climate change.

  2. It reduces the risk of invasive species establishment.

  3. It increases the efficiency of nutrient cycling.

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

High endemism reduces the risk of invasive species establishment, which can help to protect alpine ecosystems from disturbance.

Multiple choice

Which of the following is NOT a factor that contributes to the stability of alpine ecosystems?

  1. High levels of biodiversity

  2. Low levels of endemism

  3. Harsh environmental conditions

  4. Long history of human disturbance
Reveal answer Fill a bubble to check yourself
