• Biotic is life,
  Abiotic is non-living
• Biotic is non-living, Abiotic is living

Many more species of plants and animals live in a tropical forest than live in a desert. This difference is most likely due to the fact that, compared to a tropical forest, a desert (what is different about a desert?)

• has less available sunlight
• contains soil with sand
• contains less water
• has more carbon dioxide in the atmosphere

The presence of permafrost (frozen soil) makes little water available in the tundra (very cold) biome. Biodiversity in this ecosystem

• Is limited to plants that grow low to the ground and require very little water
• Is limited to animals that burrow in the snow
• Is limited to tall cone shaped trees that allow snow to roll off
• Is limited to trees that lose their leaves in the winter to conserve water

Which of the following is an example of biodiversity (variety of life in the world) supporting the sustainability of an ecosystem?

• A disease is introduced into an ecosystem and wipes out a native grass species, but grasses of other species are not affected by the disease
• Overcrowding of an ecosystem due to urban development causes a decrease in its populations
• Overcrowding of an ecosystem due to urban development causes a decrease in its populations
• An increase in the mouse population causes an increase in other herbivore populations already present in an area
