Conservation

What is extinction?

Extinction is when a species comes to an end or dies out.

What are mass extinction events?

Mass extinction events are times in the past when a very large number of species went extinct at one time.

What is a major cause of past mass extinctions?

Major and sudden shifts in the environment such as an Ice Age or an asteroid hitting the Earth.

What is the current rate of extinction caused by?

Many scientists believe that the current mass extinction is primarily caused by human activities.

List one possible reason for extinction.

Climate change, competition, hunting by humans, degradation and loss of habitats.

How does climate change affect species survival?

Climate change leads to alterations in habitats, making it difficult for certain species to survive.

What impact does competition have on species?

Competition can reduce the population size of a species.

What is a non-native species?

A non-native species is an animal or plant introduced to a new area, often causing ecological problems.

Give an example of an introduced non-native species.

Grey squirrels in the UK, which have decimated the red squirrel population.

Why is hunting by humans a concern for endangered species?

Hunting can lead to population declines, making it difficult for those species to survive.

What is one primary cause of species extinction related to habitat?

Degradation and loss of habitats due to human activity.

What role does genetic diversity play in the stability of a species?

Genetic diversity allows a species to adapt and survive environmental changes, improving its fitness.

What is biodiversity?

Biodiversity is the range and variety of genes, species, and habitats within a particular region.

What is one ecological reason for maintaining biodiversity?

Biodiversity increases the stability of ecosystems, helping them adapt to environmental changes.

Name a benefit of biodiversity in economic terms.

Many medicines are derived from plants, fungi, and bacteria, showcasing economic value.

What are national parks?

Protected areas established to conserve wildlife and the environment.

How do zoos contribute to conservation efforts?

Zoos engage in captive breeding programs for endangered species and support scientific research.

What is the function of frozen zoos?

Frozen zoos store genetic material from animals at very low temperatures for long-term preservation.

What is CITES?

The Convention on International Trade in Endangered Species of Wild Flora and Fauna, controlling trade of endangered species.

What is the purpose of seed banks?

Seed banks conserve plant diversity by storing seeds in controlled environments for future use.
