Suppose both organisms A and B eat organism C and organism B also eats organism D. A creative hypothesis might be, "Increasing the population size of A will result in organism B eating more of organism D." (Rationale: As A increases, it eats more C, which is also a food resource for B so B will have to eat more D.) You can test this by changing the population size of A and measuring the gut contents of B.
