Week 2--Assignment 3--Flow of Energy Review

Which animal is the apex (top) predator?

• hawk

• lizard

• snake

• grass

The efficiency of energy transfer from a lower trophic level to the next highest level is roughly (in other words, how much energy actually moves between each level?)

• 1%

• 10%

• 100%

• 1000%

In the energy pyramid here, how much of the energy in each level gets lost as heat or used by the organism for survival?

• 80%

• 90%

• 10%

• 20%

The arrows in a food chain or web represents what?

• They point to the organism that is being eaten.
• It shows how sunlight flows within an ecosystem.
• They show what direction the energy is flowing between organisms. 
• They represent how water is transferred within a habitat.

• All connections of energy flow throughout all organisms in a habitat.
• The specific ways that mutualism is carried out.
