What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

Why is high biodiversity important for an ecosystem?

Back

High biodiversity contributes to ecosystem stability, resilience, and productivity, allowing ecosystems to better withstand environmental changes and disturbances.

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance, playing a critical role in maintaining the structure of an ecological community.

Front

What happens to biodiversity when a keystone species is removed?

Back

Removing a keystone species typically leads to a significant decrease in biodiversity, as it can disrupt the balance of the ecosystem.

How does increased carbon dioxide contribute to global warming?

Back

Increased carbon dioxide traps more heat in the atmosphere, leading to a rise in global temperatures.

What is the impact of overfishing on shark populations?

Back

Overfishing leads to a rapid decline in shark populations, which can disrupt the entire food chain in the ocean.

Front

What is the relationship between biodiversity and ecosystem stability?

Back

Higher biodiversity generally leads to greater ecosystem stability, as diverse ecosystems can better absorb disturbances and maintain functionality.

Front

What role do predators play in maintaining biodiversity?

Back

Predators help control prey populations, which can prevent overgrazing and promote a diverse range of plant and animal species.

Front

What is the significance of genetic diversity within a species?

Back

Genetic diversity within a species is crucial for its adaptability to changing environments and resilience to diseases.

Front

How can habitat destruction affect biodiversity?

Back

Habitat destruction can lead to loss of species, reduced genetic diversity, and overall decline in ecosystem health.
