Ecology & Biogeochemical cycles

Which trophic level are primary consumers?

• First Trophic Level
• Second Trophic Level
• Third Trophic Level
• Fourth Trophic Level

Suppose the producers have 5000 kcals of energy.  How many kcals would the primary consumers receive?

• 50
• 500
• 5,000
• 50,000

Why are quaternary consumers so rare?

• It is too hard to catch prey
• There isn't enough energy left in the food
• The food sources do not taste good
• There is not enough room for them on the food chain

• Consumers
• Scavengers
• Decomposers

These gases, such as carbon dioxide, trap heat in the Earth's atmosphere causing global warming
