Ecology Quick Review

According to the image, what is the producer?

• plant

• insect

• mouse

• snake

What are "producers" producing?

• the energy for the food chain

• the insects for the food chain

The word "primary" means "first."

If that's true, what does primary consumer mean?

Hint: look carefully at the food chain!

• the first organism in a food chain

• the first organism that consumes something else for energy

According to the image, what is the primary consumer in the food chain?

• plant

• insect

• mouse

• snake

According to the image, what is the secondary consumer?

• plant

• insect

• mouse

• snake

Look carefully at the image. If energy is lost as it moves up the food chain, what trophic level has the most amount of energy?

• 1st level - producers

• 2nd level - primary consumers

• 3rd level - secondary consumers

• 4th level - tertiary consumers

The efficiency of energy transfer from a lower trophic level to the next highest level is roughly

• 1%
• 10%
• 100%
• 1000%

Trophic levels are represented by 

• squares
• circles
• pyramids
• lines

Organisms that create their own energy from sunlight or chemicals

• Herbivore
• Omnivore
• Autotroph
• Heterotroph 

Which type of organisms would be found in trophic level 2?

• Top Consumers

• Secondary Consumers

• Producers

• Primary Consumers
