Threats to Biodiversity

Front

What are invasive species?

Back

Invasive species are non-native organisms that, when introduced to a new environment, can cause harm to the ecosystem, economy, or human health.

Front

How do invasive species impact ecosystems?

Back

Invasive species can disrupt food chains, outcompete native species for resources, and alter habitats, leading to a decline in biodiversity.

Front

What is the relationship between invasive species and the economy?

Back

Invasive species can cause significant economic damage by affecting agriculture, fisheries, and tourism, leading to increased management costs.

Front

What happens to the population of smaller fish if a predator is introduced?

Back

The population of smaller fish will likely increase if a predator that eats larger fish is introduced, as there will be fewer larger fish to consume them.

Front

What are the greatest threats to biodiversity?

Back

The greatest threats to biodiversity include habitat destruction, introduction of invasive species, illegal hunting, and climate change.

Front

What does it mean for a species to be endangered?

Back

A species is considered endangered when it faces a high risk of extinction due to factors like habitat loss, disease, or predation.

Front

What is genetic diversity?

Back

Genetic diversity refers to the variety of genes within a species, which is crucial for adaptability and survival.

Front

What is biodiversity?

Back

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

Front

What is habitat destruction?

Back

Habitat destruction is the process by which natural habitats are altered or destroyed, often due to human activities, leading to loss of biodiversity.

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 and loss of biodiversity.
