Below are sample questions representative of the exercises included on this worksheet and related 3.37 Producers, Consumers, Decomposers (Extension) skill assessments:

Problem 1Difficulty: Mastery
Use the habitat data table. Which explanation best fits the changes from Week 1 to Week 4?
AThe fish became producers by Week 4.
BThe fungi turned the snails into algae.
CThe table shows that decomposers replaced all consumers.
DA drop in algae likely led to fewer snails first, and then fewer fish later.
Solution & Explanation:Algae are the producer in the table. When the producer drops, the snails that eat it may decrease first, and fish that depend on snails may decrease after that.
Problem 2Difficulty: Mastery
A student says, 'If there are more hawks, there must also be more grass right away.' Which response is best?
AYes. Every extra hawk instantly creates more producers.
BYes. Hawks make grass grow by using sunlight.
CNot always. Hawks are consumers, and any effect on grass would be indirect and may take time.
DNo. Grass is not part of any food chain with hawks.
Solution & Explanation:A change at the top of a food chain can affect lower levels, but the effect is indirect and not immediate.
Problem 3Difficulty: Mastery
Which observation is the best sign that decomposers are active after autumn leaves fall?
ALeaves move back onto trees.
BLeaves become crumbly and the soil under them gets darker.
CThe ground stops holding water forever.
DAll insects leave the area immediately.
Solution & Explanation:Crumbly leaves and darker soil show that dead material is being broken down and mixed into the soil.
