Answers to Questions:

Question 1. Draw a food chain for wheat bread to early settler.

Sun ---> wheat ---> human (early settler)

Question 2. Draw a food chain for buffalo to First Nation people.

Sun ---> grass ---> buffalo --- > human (First Nation people)

Question 3. Try drawing a more difficult food chain: northern pike (jackfish) to a person.  You may have to do some Internet research to answer this.

The reason this is more difficult is finding out what pike eat, and the food of each part of the food chain below it.  One possible answer could be the following:

Sun ---> Phytoplankton (plants) or algae ---> zooplankton (very tiny animals) ---> insects ---> small fish (minnows) ---> larger fish (perch) ---> northern pike ---> human

Question 4. What kind of food chain is the longest?

The longest food chain will have many links of animals.  A good example is the food chain that has fish in it.

Question 5. What kind of food chain is the shortest?

The shortest food chain has one producer and one animal such as the wheat to human food chain.
