Watch the 2 videos: What is biodiversity and Why is Biodiversity Threatened?
1. In your own words, write a few sentences to explain the meaning of these terms:
exotic species
introduced species
invasive species
2. A good way to increase biodiversity is by intentionally introducing a species to a new environment because the introduced species increases the species richness of that area by one species. Do you agree or disagree with this statement? Hint: Use the example of the comb jellies that were introduced to the Black Sea to explain how introduced species can cause a decrease in species richness in an area.
3. In a few sentences, explain the relationship between human population growth and threats to biodiversity.
