Grade 5 Conservation and Biodiversity
Why do some exotic animal species harm the native species?
  1. They cannot build nests.
  2. They do not have predators.
  3. They do not have prey.
  4. They cannot find food.
Grade 11 Conservation and Biodiversity
Invasive species are
  1. usually not a threat to biodiversity.
  2. rare in island habitats.
  3. successful due to a lack of natural enemies.
  4. often unable to compete effectively in the new environment.
Grade 3 Conservation and Biodiversity
Why should man not kill animals for personal profit?
  1. The animals can become extinct.
  2. Killing could destroy a food chain.
  3. both a and b
Grade 5 Conservation and Biodiversity
What is the main cause of a large number of species becoming extinct today?
  1. air pollution
  2. strip mining
  3. climate change
  4. habitat destruction
Grade 10 Conservation and Biodiversity
Ladybugs and praying mantises are examples of a natural pest controller. These organisms reduce the need for farmers to use harmful pesticides. How does biological pest control (i.e., using ladybugs instead of pesticides) contribute to sustainable development?
  1. Biological pest control helps farmers spend less money on purchasing pesticides.
  2. Biological pest control does not cause pollution that can enter the food chain or harm other organisms.
  3. Biological pest control significantly declines species populations.
  4. Biological pest control is a myth.
