Biodiversity Check for Understanding

Poll

Which of the following would be most effective in slowing the loss of biodiversity?

• required every country to maintain a seed bank

• creating large parks/preserves in biodiversity hotspots

• setting aside small plots of land in a variety of ecosystems, such as forest, grassland, and marshes

• freezing fertilized eggs of endangered animals.

Multiple Choice

Biodiversity, aka biological diversity, usually refers to

• the same species in a general location

• the number of different species in a given area

• the number of animal species in a given area

• the number of plant species in a given area

Multiple Choice

Which statement best describes an example of low species diversity?

• A population of frogs has a wide variety of skin colors

• A state park includes multiple forest, wetland, and freshwater ecosystems

• A marsh ecosystem is covered by a single species of cattail bulrushes

Multiple Choice

Which statement best describes an example of high species diversity?

• A desert ecosystem is populated only by organ pipe cacti, camels, and armadillo lizards

• A pond ecosystem is populated by a single species of frogs

• A state park includes multiple forest and freshwater ecosystems with many different species of fish, frogs, and birds

Multiple Choice

Define genetic diversity

• disturbance in the environment conditions that cause genetic changes to occur in organisms

• variety of ecosystems in a given area

• system made up of all the living and nonliving things in a given area

• variation of genes within a species or population in a given area

Multiple Choice

Why is "A" less biodiverse than "B"?

• Image "A" is more biodiverse.

• Image "A" has a lot more plants than image "B"

• image "A" has many corn plants and this makes it have high "rich" biodiversity.

• even though "A" has a lot of corn plants they are all the same species and makes this a low "poor" biodiverse area.

Multiple Choice

What is the difference between biotic and abiotic?

• Biotic are non-living things

• Abiotic are living organisms

• Biotic is life, Abiotic is non-living

• Biotic is non-living, Abiotic is living

Multiple Choice

Which represents an example of a limited biotic resource?

• low oxygen levels in a pond that can affect fish populations

• fungi destroying fruit of a banana tree of which insects feed on

Multiple Choice

Which represents an example of a limited abiotic resource?

• low oxygen levels in a pond that can affect fish populations

• fungi destroying fruit of a banana tree of which insects feed on

Multiple Choice

A species that is likely to become extinct if protective measures are not taken immediately is known as

• keystone species

• threatened species

• endemic species

• endangered species

Multiple Choice

What is an invasive species?

• A native (naturally found) species which are added to an area. 

• A non-native (not naturally found) species added to an area. 

• A keystone species in an environment

• none of the above

Multiple Choice

Invasive species alter the ecosystem by _____ in number quickly. This leads to _____ food for the native species.

• illegal hunting 

• habitat destruction

• all of the above

Multiple Choice

What does it mean when an animal is endangered?

• Place that protects animals at risk.

• animals that is at risk of extinction.

• Something once lived but no longer exists.

Multiple Choice

What does it mean when an animal is extinct?

• Something once lived but no longer exists.

• Animals that is at risk of extinction.

• Place that protects animals at risk.

Multiple Choice

Why do endangered species matter?

• Because they cannot be in the zoo

• Because they are cute

• Biodiversity

• Because if they die we cannot have them as pets

Multiple Choice

Multiple Choice

 Which biome is more likely to survive a change in the environment?

• High (rich) biodiversity

• Low (poor) biodiversity

Multiple Choice

Food Web B is an example of...

• Low biodiversity and low sustainability. If the producer dies then all the food web will suffer.

• High biodiversity and high sustainability. If an organism is removed the food web will continue with no effect.

Multiple Choice

Currently sharks are on a rapid decline due to overfishing. If sharks go extinct will this affect the biodiversity of the ocean?

• No, sharks are not important.

• No, sharks will only affect the seal populations.

• Yes, it will disrupt the entire food chain in the ocean.

• Yes, but only a little.

Multiple Choice

• True

• False

Multiple Choice

High biodiversity makes it more likely that the ecosystem will be able to keep functioning after a disturbance, such as disease or natural disaster.
