biodiversity

What has a higher biodiversity: a rain forest or a desert?

• Rain forest

• Desert

• They have a similar biodiversity

When there is higher biodiversity

• more organisms are likely to die because they can't adapt to environmental changes.
• there is less diversity.
• there is more diversity and higher sustainability of life.
• there is more diversity and lower sustainability of life

A small marine area has phytoplankton as its only producer.  Should the marine biologist be concerned about this ecosystem?

• No the fish do not need the phytoplanton. Since there are so many fish, there is high biodiversity.
• Yes, this ecosystem has low biodiversity.  Without a producer the herbivores will die out leaving no food.
• Yes, this system has high biodiversity; however the fish can adapt and get food from another source.
• Yes, the fish will overate to get all of the phytoplankton that is left, then they will die.

How do biodiversity and sustainability work together?

• The lower the biodiversity the greater the sustainability.
• The higher the biodiversity, the less sustainable the ecosystem
• The higher the biodiversity, the greater the sustainability.
• Biodiversity has nothing to do with sustainability.

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. 

What affect will continued rise in global temperature most likely have on worldwide biodiversity?

• a. It will have no effect as there is plenty of time for organisms to adapt
• b. It will increase due to warmer temperatures
• c. It will increase due to greater plant production from more CO2
• d. It will decrease due to massive habitat destruction

Environments always have both living and _________.

• nonliving factors
• bio-geochemical cycles
• nutrients
• ecosystem

An organism that uses sunlight to create its own food is known as a:

• Producer
• Heterotroph
• Consumer
• Decomposer

What is the difference between biotic and abiotic?

• Biotic are non-living things
• Abiotic are living organisms
• Biotic is life,
  Abiotic is non-living
• Biotic is non-living, Abiotic is living

Food, water, sunlight, shelter, and space are resources that are often __________.
