Review biodiversity/invasive species

The number of different species of plants and animals in area refers to what vocabulary word?

• Speciation
• Biodiversity
• Extinct
• Ecosystem

Which of the following situations is MOST HARMFUL to an ecosystem's food web or food chain?

• introduction of a similar producer
• loss of one of the top consumers
• increase in the population of producers
• disease killing the producers

Deer usually travel in groups of 2-3 sometimes more. How does staying in a group increase one deer’s chance to pass on his genes to the next generation?

• It increases the deer’s chances of survival.
• It protects the deer from the cold.
• It allows the deer to eat.
• It gives the deer time to think.

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

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

• c. The removal of plants from the food webs they support
• d. The removal of erosion barriers from forest boundaries
