Biodiversity

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

What does biodiversity mean?

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

Great Biodiversity = Great Sustainability

• True

• False

In a particular habitat, owls eat mice and mice eat grass. If the owl population suddenly grows, then most likely

• the number of mice will decrease and the amount of grass will not change.
• the number of mice will increase and the amount of grass will increase.
• the number of mice will increase and the amount of grass will not change.
• the number of mice will decrease and the amount of grass will increase.

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

What is the MOST likely consequence if a fungal disease killed the grass in this WOODLAND ECOSYSTEM?

• Only the rabbits would be affected, because they are the ones who eat the grass.
• The blueberry bush would begin to grow wild, because it would have more space to grow.
• Nothing would happen; the animals would eat something else.
• The ecosystem would most likely be disrupted, because the grass is one of its primary producers

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!

Which biome is more biodiverse?

• Desert
• Sand
• Tundra
• Rainforest

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.
