Question: Which will most likely cause a decrease in predator populations?
Answer: a decrease in prey populations
Hypothesis: a decrease of prey populations will decrease predator populations
Supporting facts: sent1: lack of food causes starvation sent2: if a new predator begins eating prey then the population of that prey will decrease sent3: more likely means increased likelihood sent4: a lack of something that a living thing requires prevents the survival of that living thing sent5: negative impacts on organisms / species will decrease the population of the organisms / the species sent6: a population is made of one type of organism in an area sent7: population is a measure of the number of a species in an environment sent8: to prey on an animal means to eat that animal sent9: the decrease of something required by an organism has a negative impact on that organism 's survival / that organism 's ability sent10: if something has a negative impact on the survival of an organism then that organism may be unable to survive sent11: as a resource required by an organism decreases , the population of that organisms will decrease sent12: avoiding predators is synonymous with avoiding being eaten sent13: a organism requires food for survival sent14: predators eat prey sent15: a required resource being low in availability has a negative impact on the something that requires that resource sent16: as a population of organisms increases , the resources used by those organisms will decrease sent17: extinction has a negative impact on an ecosystem sent18: avoiding predators has a positive impact on prey 's / an organism 's survival / health / ability to reproduce sent19: food supply often limits predator population size in an ecosystem sent20: the amount of something is similar to the availability of something sent21: positively impacting an organism 's survival increases the likelihood of survival of that organism sent22: as the population of insects decreases , the population of lizards will likely decrease because lizards eat insects sent23: if an organism eats something then that something is a source of frood to that organism sent24: as the supply of food in an environment decreases , the population of animals in that environment will decrease sent25: eating prey requires catching prey
Reasoning: [BECAUSE] a organism requires food for survival [AND] the decrease of something required by an organism has a negative impact on that organism 's survival / that organism 's ability [INFER] int1: a decrease of food has a negative impact on organisms [BECAUSE] int1 [AND] negative impacts on organisms / species will decrease the population of the organisms / the species [INFER] int2: a decrease of food for an organism will decrease that organism's population [BECAUSE] predators eat prey [AND] if an organism eats something then that something is a source of frood to that organism [INFER] int3: prey is a kind of food for predators [BECAUSE] int2 [AND] int3 [INFER] int4: a decrease of prey will decrease predator [BECAUSE] int4 [AND] population is a measure of the number of a species in an environment [INFER] int5: a decrease of prey populations will decrease predator populations
