Question

trees shrubs grass the diagram, which shows how energy moves through an ecosystem, is known as a: a. habitat. b. food net. c. food chain. d. food web.

Explanation:

• Option A: A habitat is the natural environment where an organism lives, not a diagram of energy flow. Eliminate A.
• Option B: "Food net" is not a standard ecological term. The correct term for interconnected food chains is food web, but this option is misnamed. Eliminate B.
• Option C: A food chain shows a linear sequence of organisms where each is eaten by the next, representing energy flow. The diagram likely depicts a simple energy - flow sequence (though the image has producers like trees, shrubs, grass which start a food chain).
• Option D: A food web is a complex network of multiple food chains. The diagram here (with trees, shrubs, grass as producers) is more likely a simple food chain (starting point of energy flow) rather than a web (which would have multiple consumers and interconnections). So the best fit is a food chain.

Answer:

C. food chain
