If there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?

• 10 Kcal
• 1 Kcal
• 100 Kcal
• 1000 Kcal

Which organism recieves the least amount of energy from the producer?

• Owl
• Grasshopper
• Lilypad
• Mouse

In the energy pyramid here, how much of the energy in each level gets lost as heat?

• 80%

• 90%

• 10%

• 20%

What is the correct order of changes during primary succession?

• Climax community, consumers, producers, pioneer species

• Soil, producers, consumers, climax community

• New rock, pioneer species, producers, consumers, climax community

What is the order that plants grow to repopulate the area in primary succession, such as a glacier receding or a volcano covering land with lava?

• Lichens → Shrubs → Grasses → Trees

• Lichens → tree → shrubs→Grasses

• Grasses → Lichens → Shrubs → Trees

• Lichens → Grasses → Shrubs → Trees

What type of symbiosis?  Hummingbirds feed on nectar from flowers.  The flowers are pollinated by hummingbirds as they move from flower to flower.

• commensalism
• mutualism
• parasitism
• predation
