Textbook Question
Chapter 58.5, Problem 1CS
Core Skill: Connections In the two food chains illustrated in Figure 58.13, plants and protists (phytoplankton) are the producers. Refer back to Section 27.4. What other organisms are producers and could also support food chains?
Figure 58.13 Food chains. Two examples of the flow of food energy up the trophic levels: a terrestrial food chain and an aquatic food chain.

Food Web Construction
Directions: Construct a food web using the following organisms (grass,leaves,owl,
snake,grasshopper,hawk,bird,caterpillar,rabbit) Use Words to Construct. And answer the question that follow
1What is/are the producer(s) in the food web?
2What organism(s) feed directly on plants?
3What is/are the secondary consumer(s) in the food web?
4What is/are the tertiary consumer(s) in the food web?
Construct your model of the food chain/web by moving and linking (using arrows leading from those that eat and those that are eaten) all 8 images of the different species (trophic components).

- The average efficiency of energy transfer between trophic levels is 10%. Use this efficiency to determine how much phytoplankton mass is required to add just 1 gram (0.04 ounce) of new mass to a killer whale, which is a third-level or top carnivore.
