Question

the food chain
all living organisms require energy to survive and perform life processes. this energy originates from the sun. organisms that convert sunlight into energy through photosynthesis are called producers—examples include grasses and seaweeds. organisms that consume other organisms to obtain energy are called consumers. these are categorized into levels.
. primary consumers eat producers (e.g., rabbits, sea urchins)
. secondary consumers eat primary consumers (e.g., foxes, seals).
. tertiary consumers eat secondary consumers (e.g., owls, killer whales).
a food chain illustrates how energy flows from the sun to producers and then through various levels of consumers. for instance, in a food chain involving a fox, energy flows from the sun → grass (producer) → rabbit (primary consumer) → fox (secondary consumer).

1. which statement best summarizes the passage?

a. secondary consumers feed on primary consumers for energy
b. tertiary consumers feed on secondary consumers.
c. in a food chain, energy flows from the sun to producers and then to consumers
d. all green plants are producers.

Explanation:

The passage overall describes the concept of the food - chain, starting from the sun as the energy source, passing through producers, and then different levels of consumers. Options A and B only focus on specific consumer - consumer relationships, and option D only mentions producers. Option C encompasses the overall idea of energy flow in a food chain as described in the passage.

Answer:

C. In a food chain, energy flows from the sun to producers and then to consumers
