Question

lesson 6 interpret diagrams
1 learn the skill
diagrams show relationships between ideas, objects, or events in a visual way. diagrams also can show the order in which events occur. when you interpret diagrams, you find out how objects or events relate to one another.
2 practice the skill
by practicing the skill of interpreting diagrams, you will improve your study and test - taking abilities, especially as they relate to the ged® science test. study the information and diagram below. then answer the question that follows.
a diagrams can take many forms. flowcharts use boxes and arrows to show steps in a process or order of events. some flowcharts are circles or ovals. they show events that occur in cycles.
b the parts of this diagram are arranged in a line, with arrows pointing from one part to the next. the arrows show the direction in which energy flows from one organism to the next.
ecosystems
an ecosystem includes all the living things in an area, along with their nonliving environment. energy flows through the living parts of an ecosystem. in most ecosystems, the energy originates from the sun. plants use energy from sunlight and nutrients from air, water, and soil to make food. animals eat the plants, other animals eat the plant eaters, and so on. each organism gets energy from its food and passes on energy to any organism that feeds on it. a food chain shows a single path of feeding relationships among certain organisms in an ecosystem. the diagram shows a food chain in a grassland ecosystem.
test - taking tips
review the answer choices.
how would the diagram have to look for each answer choice to be true? compare the imagined diagram with the actual diagram to determine the correct answer.

1. which statement describes a feeding relationship shown in the diagram?

a. hawks eat grass.
b. grasshoppers eat sparrows.
c. sparrows eat grasshoppers.
d. hawks eat grasshoppers.

Explanation:

To solve this, we analyze each option using the food chain diagram (Grass → Grasshopper → Sparrow → Hawk, with arrows showing energy flow (who eats whom)).

• Option A: Hawks eat grass? The diagram shows hawks eat sparrows, not grass. Eliminate A.
• Option B: Grasshoppers eat sparrows? The arrow is from grasshopper to sparrow (sparrow eats grasshopper), so B is wrong.
• Option C: Sparrows eat grasshoppers? The arrow from grasshopper to sparrow confirms this (energy flows from grasshopper to sparrow, meaning sparrow eats grasshopper). This matches.
• Option D: Hawks eat grasshoppers? The diagram shows hawks eat sparrows, not grasshoppers. Eliminate D.

Answer:

C. Sparrows eat grasshoppers.
