Biodiversity/Succession Review

Which biome is more biodiverse?

• Desert

• Grassland

• Tundra

• Rainforest

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

• High (rich) biodiversity
• Low (poor) biodiversity

What does biodiversity mean?

• Only one species in an area.
• The different amount of species in an area
• All abiotic life
• Nitrogen fixation

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

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.

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.

Why is biodiversity important in fighting disease in food crops?

• It prevents one disease from wiping out an entire food crop.
• It prevents habitat loss of native species.
• It provides different foods for different populations.
• It prevents fungal disease from wiping out corn crops.

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

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.

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!
