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 variety of genes within a species, which contributes to the adaptability and survival of the species.

Front

What is the main cause of biodiversity loss worldwide?

Back

The main cause of biodiversity loss worldwide is habitat destruction.

Front

What are r-strategists?

Back

R-strategists are species that reproduce quickly and in large numbers, often in unstable environments. An example is a dandelion.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where soil is already present after a disturbance.

Front

How do environmental stressors affect biodiversity?

Back

Environmental stressors, such as wildfires, can reduce biodiversity, but ecosystems with higher species diversity are more likely to recover after disturbances.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a final stage of ecological succession.

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new habitat, often causing harm to native species and ecosystems.

Front

What is habitat fragmentation?

Back

Habitat fragmentation is the process where large habitats are broken into smaller, isolated patches, negatively impacting species that require large territories.

Front

What is an ecosystem?

Back

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