What is biodiversity?

Back

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

Front

What is genetic diversity?

Back

Genetic diversity is the variation of genes within a species or population in a given area.

Front

Why is high biodiversity important for ecosystems?

Back

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

Front

What is ecosystem diversity?

Back

Ecosystem diversity refers to the variety of ecosystems in a given area.

Front

How does low biodiversity affect a population?

Back

Low biodiversity can make a population more susceptible to diseases and environmental changes, as there is less genetic variation to provide resilience.

Front

What is an example of a stable ecosystem?

Back

A rainforest is an example of a stable ecosystem with high biodiversity, supporting a wide range of species and interactions.

Front

What does it mean if an area has poor biodiversity?

Back

An area with poor biodiversity has a low variety of species, which can lead to ecological imbalances and increased vulnerability to disturbances.

Front

What role do keystone species play in an ecosystem?

Back

Keystone species are crucial for maintaining the structure of an ecosystem; their removal can lead to significant changes in the ecosystem.

Front

What is the relationship between biodiversity and ecosystem services?

Back

Higher biodiversity enhances ecosystem services such as pollination, water purification, and climate regulation, benefiting human well-being.

Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads rapidly in a new environment, often outcompeting native species and disrupting ecosystems.
