MULTI-CHOICE: Which are ways that biodiversity keeps ecosystems healthy?

• If one species is threatened others can take its place.

• More species = more genetic variety.

• Different species have different jobs (niches) that keep ecosystems healthy.

• Food webs do not have enough species to be sustainable.

Which of the following are FALSE about biodiversity?

• If one species is threatened there may be others to take its place.

• Diverse species are NOT good for human health or economics (making money).

• Many of one species means there is a better chance of genetic diversity.

• Different species have different jobs (niches) and each job is important.

Some people believe that the Earth is currently experiencing its sixth mass extinction

because_____________

• The rates of extinction are happening gradually

• The Earth's climate has stayed relatively unchanged

• The rates of extinction has greatly increased due to human actions

• There are now laws to protect the habitats of many species

The world is experience a loss of genetic diversity within species. More people on Earth and our increasing use of natural resources has reduced space and resources for wild species. Which are true about the loss of GENETIC DIVERSITY:

• Over time, many wild animal and plant populations have become smaller or more isolated.

• Many species have gone through local extinctions.

• Many species are less able to adapt when facing things like climate change, pollution, and new diseases.

• Species are not being impacted and biodiversity is thriving across the world.

Why do the populations of invasive species grow so quickly? 

• Invasive species are native to an area. 

• Invasive species are prey to many animals.
• Invasive species have no natural predators in the area.

• Invasive species keep the ecosystems in equilibrium.
