Question

a family raises a species of fish in a pond. at the end of each summer, the family sells the fully grown fish. one year, the family notices that the fish are smaller than they had been the previous year. which statement best explains this observation? (1 point) there were fewer fish this year than there were last year. there was more space in the pond this year than last year. there was less food available in the pond this year than last year. the type of fish in the pond this year tended to be smaller than the type of fish last year.

Explanation:

To determine the best explanation for the fish being smaller, we analyze each option:

• Option 1: Fewer fish would likely mean more resources per fish, so they should be larger, not smaller. Eliminate.
• Option 2: More space would also mean more resources, leading to larger fish. Eliminate.
• Option 3: Less food means fish have fewer nutrients to grow, so they would be smaller. This is consistent with the observation.
• Option 4: The problem states it is the "same species" (implied by "a species of fish" being raised), so the type of fish is not the issue. Eliminate.

Answer:

C. There was less food available in the pond this year than last year.
