Biodiversity & Succesion

Front

What is biodiversity?

Back

Biodiversity refers to the variety of different species in a specific area, including the diversity of genes, species, and ecosystems.

Front

What is habitat destruction?

Back

Habitat destruction is the process in which natural habitat is rendered unable to support the species present, often due to human activities such as deforestation, urbanization, and agriculture.

Front

What is an invasive species?

Back

An invasive species is a non-native species that, when introduced to a new environment, outcompetes local species for resources, often leading to ecological imbalance.

Front

What is the primary cause of extinction?

Back

The primary cause of extinction is habitat destruction and fragmentation, which reduces the living space and resources available for species.

Front

What is the role of pollution in biodiversity loss?

Back

Pollution can lead to the degradation of ecosystems, harming species and reducing biodiversity by contaminating air, water, and soil.

Front

What is the significance of the Bald Eagle in conservation?

Back

The Bald Eagle is a symbol of successful conservation efforts, having recovered from the brink of extinction due to DDT contamination and habitat protection.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What are keystone species?

Back

Keystone species are species that have a disproportionately large impact on their environment relative to their abundance, playing a critical role in maintaining the structure of an ecological community.

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 a disturbance has destroyed an existing ecosystem but soil and some organisms still remain.

Front

What is the impact of overfishing on marine biodiversity?

Back

Overfishing depletes fish populations, disrupts food webs, and can lead to the collapse of marine ecosystems, significantly reducing biodiversity.
