NPP + threats to biodiversity

What is FALSE about exotic and invasive species?

• Exotic species harm the native population

• Invasive species harm to the native population

• They both are nonnative to the location

• They are away from their usual preditors

What is an example of overexploitation?

• Building a city

• Throwing chemicals in the water

• Releasing lion fishes in a new location

• Overharvesting

What is NOT an effect of climate change?

• Coral bleaching

• Lack of gene flow

• Endangered species

• Lakes drying up

Which will NOT increase NPP?

• Functional diversity of plants

• Species richness

• Species evenness

• Biodiversity

What is the course of chemical energy used in the food web?

• Oxygen

• NPP

• Water

• All of the above

What would NOT be an example of species richness positively impacting NPP?

• Plant assemblages with lots of diversity absorbing more CO2

• Desert mosses stabilize sand grains for great downstream effect to the ecosystem

• All of the above

What is the MOST important threat to biodiversity?

• Invasive species

• Habitat loss

• Pollution

• Overexploitation

What kind of ecosystem would have the highest NPP?

• One with the least diversity and richness

• One with the most richness and evenness

• One with the most diversity and richness

• One with the least richness and evenness

What does resilience mean?

• Measure of how strong a disaster was

• Measure of how quickly a community recovers following a disturbance

• Measure of how much a community is affected by a disturbance

• How much force is needed to push you down

What does resistance mean?

• Measure of how strong a disaster was

• Measure of how quickly a community recovers following a disturbance

• Measure of how much a community is affected by a disturbance

• How much force is needed to push you down
