The number of different species in an area

• purification

• recycling

• biodiversity

• oceanic

• terrestrial

• health

• sustainable

• resources

• organisms

The environment with the greatest biodiversity is the one with the greatest variety of _____.

• health

• resources

• organisms

Changes in biodiversity can influence humans’ _____ as well as _____ (pick both).

How do humans benefit from ecosystems?

• We get food, shelter, water, etc. We also negatively and positively impact the health of the ecosystem.

• We get food, shelter, water, etc. We also positively impact the health of the ecosystem.

• We get food, shelter, water, etc. we also negatively impact the health of the ecosystem.

• no

If you cut down a forest for a housing development, what can you predict will happen to the overall health and sustainability of the ecosystem over time?

• Removing organisms from an ecosystem decreases its sustainability and stability, leading to its decline.

• Removing organisms from an ecosystem decreases its sustainability and stability, leading to its tremendous success.

• no

• still no

If we lose genetic diversity in our food sources

• We lose sources of DNA and new possible food sources

• We gain sources of DNA and new possible food sources

• We find new varieties of food to use

This is the extinction of a species one by one, not a sudden loss of many species

• background extinction

• mass extinction

• fragmentation

• biotic potential

This classification of risk means that the species is at serious risk of extinction.

• threatened

• vulnerable

• endangered

• extinct

The status of a "threatened species" means:

• they are almost extinct

• they are likely to become endangered

• they are extinct

• their numbers are increasing
