Biodiversity

Where does the energy from an ecosystem come from?

• Trees
• Sun
• Plants
• Water

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

What does biodiversity mean?

• Nitrogen fixation

A drought has hit this grassland biome. How will this effect the rabbit population?

• The rabbits will increase in number.
• The rabbit population will stay the same.
• The rabbit population will decrease.
• The rabbit population will become extinct immediately.

Brown trout consume (eat) more tadpoles when the fly larvae reduce in number (decrease).  This proves...

• The dependence of organisms and biodiversity in an ecosystem
• Diversity increases as organisms decrease
• Losing an animal is good for ecosystems
• Changes in ecosystems create new organisms

Which of the following situations contributes to stability in an ecosystem?

• increase in biodiversity

• decrease in biodiversity

• extinction of a population from the ecosystem

• removal of many populations of organisms

Why does biodiversity contribute to a habitat’s sustainability?

• The more plants and animals in a habitat, the greater the biomass, which is how habitats store energy.

• The greater the number of species, the more competition there is for food between predators, which sustains their populations.

• Changing conditions that harm one species leave other species to survive and perhaps even thrive.

• Landforms change shape less frequently when there is a greater number of species using the land.

Which biome is more biodiverse?

• Desert
• Sand
• Tundra
• Rainforest

What do biologist call an ecosystem that has reached its maximum potential?

• Rainforest 
• Environment
• Climax Community

Which option is biotic?
