Biodiversity and Ecosystem Sustainability

Front

What is biodiversity?

Back

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

Front

Why is biodiversity important for ecosystems?

Back

Biodiversity is crucial for ecosystem stability, resilience, and productivity. It helps ecosystems recover from disturbances and provides essential services like pollination, nutrient cycling, and climate regulation.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What is the impact of extinction on biodiversity?

Back

Extinction reduces biodiversity, leading to less resilient ecosystems and the loss of potential resources, such as medicines and food.

Front

What are aquatic ecosystems?

Back

Aquatic ecosystems are water-based environments that include freshwater (lakes, rivers) and marine (oceans, coral reefs) ecosystems.

Front

What is a taiga?

Back

Taiga, also known as boreal forest, is a biome characterized by coniferous forests, cold temperatures, and moderate precipitation, and it is not an aquatic ecosystem.

Front

How does biodiversity affect ecosystem resilience?

Back

Higher biodiversity increases ecosystem resilience, allowing it to better withstand and recover from environmental changes and disasters.

Front

What is the difference between a rainforest and a tundra in terms of biodiversity?

Back

Rainforests have high biodiversity due to their warm, wet climate, while tundras have low biodiversity due to harsh, cold conditions.

Front

What does it mean when we say Earth's biodiversity is decreasing?

Back

It means that the number of species and genetic diversity is declining, often due to human activities like habitat destruction, pollution, and climate change.

Front

What role do keystone species play in an ecosystem?

Back

Keystone species have a disproportionately large impact on their ecosystem, helping to maintain its structure and balance.
