Biodiversity

What does biodiversity mean?

• The number of different species that live in an ecosystem
• The population of a single species in an ecosystem
• The amount of abiotic resources an ecosystem has
• Only the types of producers that are found in an ecosystem

How does biodiversity increase ecosystem stability?

• It decreases the amount of predators and stabilizes prey
• It increase the amount of producers that are available for food
• It decrease genetic diversity, which is important for stability
• There are more resources and more connections on the food web

Why is biodiversity important to humans?

• Different species provide us with materials for building
• Different species provide materials that we make clothes with
• All of our food come from different species
• Different species provide many of our medical compounds
• All of the above.

Give an example of how humans get medicines from the biodiversity of life.

Why do deserts tend to have low biodiversity?

• Because the environment conditions are harsh
• Because the producer population is abundant
• Because deserts tend to have farms

Explain why farms are considered to have very low biodiversity

What is true about ecosystems with very high biodiversity?

• They are unstable and threatened by environmental changes
• They more stable and are more likely to remove from environmental changes.
• They have so much competition that it harms most organisms
• The environmental conditions tend to be very harsh in these ecosystems
