Biodiversity

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

How can humans best help an endangered species avoid extinction?

• they can feed the animals
• they can put the animals in a zoo
• they can protect the animal’s habitat
• they can take the animal to new habitats

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!

What factor does NOT affect biodiversity?

• Urbanization
• Planting Native Plants
• Overfishing
• Pollution

• b. It had a lot of resistance to disease
• c. It had a few plants that were resistant to disease
• d. It had too much genetic variation

In what way are humans most impacting the biodiversity of ecosystems around the world?

• a. We are putting too many organisms in zoos or keeping them as pets
• b. We are increasing biodiversity by breeding new species
• c. We are destroying the habitats of a large number of species
• d. Recreational hunting

What does biodiversity mean?

• All abiotic life
• Nitrogen fixation

• population
• species
• community

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

• Image "A" is more biodiverse.

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

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

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

High biodiversity is 

• having a lot of the same organism.
• having a few of the same organism.
• having a lot of variety of different organisms.
• only having one of each organism.
