• 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

Image "B" shows more biodiversity than image "A". Why?

• Because "B" shows more different species than image "A"

• Because image "B" has less different species than "A"

• "A" has a greater number of same species plants so this statement is wrong.

• Both images show the same biodiversity

Biodiversity is important to keep an area (biome) healthy. In this example "Food Web A" is sustainable. Why is sustainability important for an ecosystem in "Food Web A".

• If one organism is removed the food web can still operate (work) with little or no negative effect.

• If an organism is removed the food web will collapse and will affect the environment.

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.

Soccer fields are most often made of one single type of grass. What type of biodiversity do sports fields show?

• High "Rich" biodiversity because there is only one type of producer.

• Low "Poor" biodiversity because there is only one type of producer.

Biodiversity is best described as...

• the amount of different species of organisms (plants and animals) living in the same area.

• when only a few species inhabit an area.

• when only one organism (plants and animals) is found living in one area.

Which habitat exhibits the greatest biodiversity?

• A habitat with 15 different species with about 300 individuals each
• A habitat with 10 different species with about 75 individuals each
• A habitat with 4 different species with about 150 individuals each
• A habitat with only one species with about 2000 individual

Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
• Because it’s better to have only one variation of each species.
• Because it better to only have a few species on Earth.
• Honestly, I have no idea what biodiversity is!
