Below are sample questions representative of the exercises included on this worksheet and related 3.36 Read a Food Chain Diagram (Extension) skill assessments:

Problem 1Difficulty: Mastery
Which answer best identifies the roles and traces energy flow in a simple local food chain?
AIn pondweed -> insect larva -> fish -> heron -> bacteria, pondweed is the producer, the animals are consumers, bacteria are decomposers, and energy moves toward the eater at each arrow.
BIn the same chain, fish is the producer, heron is the decomposer, and arrows point to what gets eaten.
CIn the same chain, bacteria are producers, and energy starts with the fish.
DIn the same chain, the heron makes its own food, so it is the producer.
Solution & Explanation:This answer correctly identifies the producer, consumers, decomposer, and the direction of energy flow.
Problem 2Difficulty: Mastery
A diagram shows a pond food chain with Sun -> pondweed -> snail -> fish -> heron and bacteria connected to the dead plants and animals. Which statement is correct?
APondweed is the producer, snail and fish are consumers, and bacteria are decomposers.
BSnail is the producer, pondweed is the consumer, and heron is the decomposer.
CBacteria are the producer because they are at the end.
DHeron gives energy directly to the Sun.
Solution & Explanation:Pondweed is the producer, the snail and fish are consumers, and bacteria break down dead organisms as decomposers.
Problem 3Difficulty: Mastery
Which sequence correctly shows how energy can move from sunlight to a decomposer in a forest?
ASun -> berry bush -> mouse -> snake -> bacteria
BSun -> bacteria -> mouse -> berry bush -> snake
Csnake -> mouse -> berry bush -> bacteria -> Sun
DSun -> mouse -> berry bush -> snake -> bacteria
Solution & Explanation:Energy starts with sunlight, moves to the producer, then through consumers, and finally to a decomposer when organisms die.
