Final answer:
The question refers to an assignment where students used visual representations to analyze a problem concerning living systems' interactions and the movement of matter and energy. The Work It Out feature indicates they approached the problem step-by-step. Without the specific text, only a general inference can be made.
Step-by-step explanation:
The provided details do not contain the specific narrative of how four students at Whittier Regional Vocational Technical High School solved a problem for Molly Rizk. However, based on the context of the keywords and the subject matter, we can infer that the students might have used visual representations to analyze and solve a problem related to the interactions between living systems and their environment. This would involve understanding and illustrating the movement of matter and energy, possibly via food webs, energy pyramids, or material cycles.
The Work It Out feature suggests that the students would follow a systematic, step-by-step approach to solve the problem analytically or computationally, which means they would break down the problem into smaller parts and solve each step one at a time to reach a qualitative solution.
