Multiple choice

Which of the following is NOT a major threat to coral reefs?

  1. Overfishing

  2. Climate change

  3. Pollution

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

Overfishing is a major threat to coral reefs, as it disrupts the delicate balance of the ecosystem. However, it is not a direct threat to coral reefs, unlike climate change, pollution, and coral bleaching, which can cause significant damage and degradation to coral reef ecosystems.

Multiple choice

What is the primary cause of coral bleaching, a phenomenon that leads to the loss of coral color and vitality?

  1. Increased water temperature

  2. Pollution

  3. Overfishing

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

Coral bleaching is primarily caused by increased water temperature, often due to climate change. When water temperatures rise above the optimal range for coral survival, they expel the symbiotic algae that provide them with nutrients and color, leading to coral bleaching and potential death.

Multiple choice

What are the consequences of the shifting distribution of plant and animal species in India's mountains?

  1. Loss of biodiversity.

  2. Changes in ecosystem dynamics.

  3. Increased risk of extinction.

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

The shifting distribution of plant and animal species in India's mountains can lead to loss of biodiversity, changes in ecosystem dynamics, and increased risk of extinction.

Multiple choice

Which of the following is a major threat to the natural vegetation of India?

  1. Climate Change

  2. Pollution

  3. Invasive Species

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

Climate change, pollution, and invasive species are all major threats to the natural vegetation of India. Climate change is causing changes in temperature and precipitation patterns, which can lead to changes in vegetation distribution and composition. Pollution can damage vegetation and make it more susceptible to pests and diseases. Invasive species can compete with native plants for resources, leading to a decline in biodiversity.

Multiple choice
