Biodiversity

What is the greenhouse effect?

• The greenhouse effect is the warming of a planet due to trapped radiation.

• The greenhouse effect is the cooling of a planet due to increased cloud cover.

• The greenhouse effect is the process of plants absorbing sunlight for photosynthesis.

• The greenhouse effect is the phenomenon of water vapor condensing in the atmosphere.

How does increased carbon dioxide contribute to global warming?

• By reflecting sunlight back into space.

• By trapping more heat in the atmosphere.

• By increasing the Earth's albedo effect.

• By promoting cloud formation that cools the planet.

What is the impact of climate change on biodiversity?

• Climate change has no effect on biodiversity.

• Climate change improves biodiversity by creating new habitats.

• Climate change impacts biodiversity by altering habitats, shifting species distributions, and increasing extinction rates.

• Climate change only affects terrestrial species, not aquatic ones.

How does pollution affect biodiversity?

• It enhances species diversity by creating new habitats.

• It has no effect on biodiversity.

• It affects biodiversity by contaminating habitats, harming species, and disrupting ecosystems.

• It only affects air quality, not biodiversity.

What is habitat destruction?

• The process of creating new habitats for wildlife.

• The process in which natural habitat becomes incapable of supporting its native species.

• The act of preserving natural habitats from human interference.

• The method of restoring damaged ecosystems.

What is an example of a keystone species?

• Sea otter

• Great white shark

• Bald eagle

• Red fox

Why is biodiversity important for ecosystems?

• It increases the risk of extinction of species.

• It enhances resilience, productivity, and stability.

• It reduces the availability of resources.

• It leads to uniformity in species.

What is the significance of genetic diversity?

• It allows populations to adapt to changing environments and resist diseases.

• It increases the likelihood of extinction in species.

• It reduces the ability of populations to survive environmental changes.

• It leads to uniformity in traits among species.

What environmental problem is mainly associated with burning fossil fuels?

• Acid rain

• Ozone depletion

• Global warming

• Deforestation

What is the primary cause of ocean acidification?

• The absorption of carbon dioxide by ocean water.

• Increased levels of nitrogen in the ocean.

• Overfishing of marine species.

• Pollution from plastic waste.
