PEOPLE AND EARTH ECOSYSTEM part 2

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. 

This picture is a great example of ____________ biodiversity.

• high
• moderate
• low
• hhhmmmm there is no way to know without counting.

Different biomes support different varieties of organisms.  Think of a desert biome.  In this environment you will see organisms that have adapted to the heat and low availability of water, such as a cacti, mouse or rattle snake.  In which biome would you find an animal that has padding on its feet, white fur?

• Desert
• Tundra
• Forest 
• Savannah

An organism has 
*  long legs
*  no fur on it belly
*  hunts at night (nocturnal)
In what biome would we find this organism?

• Grassland
• Desert
• Tundra
• Forest

This organism has a special adaptation that allows it to absorb oxygen.  Where would you see this organism?

• Desert, where there is little water and hot temperatures.
• Tundra, where the animal lives at high altitudes and there is less breathable oxygen.
• Marine, Salt water or fresh waster where the oxygen must be absorbed from the water.
• All organisms have this adaptation.
