What is Biodiversity?

Biodiversity, the variety of species on Earth, is crucial for healthy ecosystems. It provides food, medicine, and materials, and supports life-supporting services like pollination and water purification. However, biodiversity is rapidly decreasing, threatening these resources and ecosystem stability. Conserving biodiversity is essential for our survival and is considered a moral responsibility.

What is the term used to describe the variety of living species on Earth?

• Ecology

• Habitat

• Biodiversity

• Ecosystem

Why is high biodiversity crucial for ecosystems?

• It decreases the variety of habitats.

• It increases the number of predators.

• It helps ecosystems resist changes.

• It reduces the number of species.

How does a reduction in biodiversity threaten future resources?

• By increasing the number of species.

• By promoting the growth of invasive species.

• By limiting access to food, medicine, and materials.

• By enhancing the stability of ecosystems.

Which of the following is NOT a service provided by diverse species?

• Purifying water

• Pollinating plants

• Increasing soil erosion

• Cleansing the atmosphere

What is one reason we need to conserve biodiversity?

• To promote human dominance

• To reduce the variety of life forms

• To ensure ecosystem stability

• To increase the number of species
