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.

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. Its removal can lead to significant changes in the ecosystem.

How does a larger gene pool affect survival?

Back

Organisms with a larger gene pool have a greater chance of surviving because they have more genetic variation, which can enhance adaptability to changing environments.

Front

What is the impact of habitat destruction on biodiversity?

Back

Habitat destruction leads to loss of species and reduces biodiversity, as many organisms depend on specific habitats for survival.

Front

What happens to the food web if a keystone species goes extinct?

Back

The extinction of a keystone species can disrupt the entire food web, leading to population declines or increases in other species and overall ecosystem imbalance.

Front

What is the relationship between biodiversity and ecosystem sustainability?

Back

High biodiversity contributes to ecosystem sustainability by providing resilience against environmental changes and disturbances.

Front

What are some human activities that threaten biodiversity?

Back

Human activities such as habitat destruction, pollution, overfishing, and climate change threaten biodiversity by altering or destroying natural habitats.

Front

What is the significance of genetic diversity within a species?

Back

Genetic diversity within a species is crucial for its adaptability and survival, allowing populations to cope with environmental changes and resist diseases.

Front

How do invasive species affect local biodiversity?

Back

Invasive species can outcompete native species for resources, disrupt food webs, and lead to declines in native biodiversity.

Front

What role do producers play in a food web?

Back

Producers, such as plants and phytoplankton, form the base of the food web by converting sunlight into energy through photosynthesis, supporting all other trophic levels.
