Biodiversity Review

Front

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 an invasive species?

Back

An invasive species is a non-native species that is introduced to an area and can cause harm to the environment, economy, or human health.

Front

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, helping to maintain the structure of an ecosystem.

Front

What are the main threats to biodiversity?

Back

Main threats include habitat loss, invasive species, pollution, overhunting, and climate change.

Front

What is biomagnification?

Back

Biomagnification is the process by which the concentration of toxic substances increases in organisms at each successive level of the food chain.

Front

What role do sea otters play in coastal ecosystems?

Back

Sea otters are a keystone species that help maintain the health of kelp forests by preying on sea urchins, which can overgraze kelp if not controlled.

Front

What is habitat loss?

Back

Habitat loss is the destruction or alteration of the natural environment, often due to human activities such as urban development, agriculture, and deforestation.

Front

How do invasive species affect native species?

Back

Invasive species can outcompete native species for resources, introduce diseases, and disrupt local ecosystems, leading to declines in native populations.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the survival of species, as it increases resilience to diseases, environmental changes, and allows for adaptation.

Front

What is conservation biology?

Back

Conservation biology is the scientific study of how to protect and restore biodiversity, focusing on the preservation of species, habitats, and ecosystems.
