What role do large fruit eaters like spider monkeys play in the environment?

• They consume large amounts of insects, keeping their populations in check.

• They are mainly responsible for pollinating flowers.

• They spread the seeds of tropical hardwood trees, aiding forest growth.

• They primarily hunt smaller animals, controlling their populations.

Approximately how many species have been catalogued by humans?

• Around 1.6 million species

• More than 3 million species

• About 500,000 species

• Nearly 2 million species

Why is protecting the planet's biodiversity crucial?

• It supports essential services like food provision, medicine, and ecosystem protection.

• Biodiversity primarily provides recreational benefits.

• It ensures the survival of only the most visually appealing species.

• It is only important for maintaining aesthetic natural landscapes.

What is a major threat to biodiversity mentioned in the text?

• The introduction of non-native species exclusively.

• Climate change and its effects on habitats.

• Solely the pollution of oceans.

• Only the overuse of water resources.

How many mammal species are at risk of being consumed to extinction?

• About 100 mammal species

• Over 500 mammal species

• Less than 50 mammal species

• More than 300 mammal species

What happened to the corals in the Great Barrier Reef during 2016 and 2017?

• They expanded their territory significantly.

• Their colors brightened due to increased sunlight.

• Nearly half of them died due to sea warming.

• They were unaffected by environmental changes.

What is one of the suggested actions to combat the biodiversity crisis?

• Increasing urban development to reduce wild areas.

• Focusing solely on reducing air pollution.

• Limiting biodiversity protection to hotspots only.

• Using land and water in ways that minimize environmental damage.

What was a significant achievement in the South of England in 2020?

• White stork chicks hatched for the first time in 600 years.

• The introduction of a new species of tree that grows rapidly.

• A record number of tourists visited natural reserves.

How was the population of mountain gorillas in Virunga National Park restored?

• By relocating gorillas from other regions to increase genetic diversity.

• Using tourism revenue to support coexistence with human communities.

• By introducing new predators to control their numbers.

• Through selective breeding programs.
