Question: The number of fish in a lake suddenly increases. How will the increase most likely affect the lake?
Answer: There will be fewer insects in the lake.
Hypothesis: if the number of fish in a lake increases there will be fewer insects in that lake
Supporting facts: sent1: predators eat prey sent2: if an animal eats other animals for food , then the animal will be the predator sent3: as temperature in an environment decreases , the amount of water an animal in that environment will lose will decrease sent4: a predator eats other animals for food sent5: less means a reduced amount sent6: polluting means something poisonous is added to an environment sent7: eating something decreases the amount of that something sent8: population is a measure of the number of a species in an environment sent9: insects eat plants sent10: as population of predators increases , the population of prey will decrease in an environment sent11: if something has a negative impact on something else then increasing the amount of that something has a negative impact on that something else sent12: to reduce means to decrease sent13: humans changing ecosystems / environments usually has a negative impact on an ecosystem / organisms living in an ecosystem sent14: if an organism eats something then that something is a source of frood to that organism sent15: the decrease of something required by an organism has a negative impact on that organism 's survival / that organism 's ability sent16: harming an environment causes harm to the living things / to the organisms in that environment sent17: most predators live in / live near the same environment as their prey sent18: if something decreases in number then there will be fewer of that something sent19: a body of water is a kind of environment sent20: decreasing something negative has a positive impact on a thing sent21: fish eat insects sent22: humans sometimes eat fish sent23: a lake is a kind of body of water sent24: predators / carnivores / omnivores eat other animals sent25: negative impacts on organisms / species will decrease the population of the organisms / the species
Reasoning: [BECAUSE] a body of water is a kind of environment [AND] a lake is a kind of body of water [INFER] int1: a lake is a kind of environment [BECAUSE] int1 [AND] as population of predators increases , the population of prey will decrease in an environment [INFER] int2: as the population of predators in a lake decreases the population of prey will decrease in that lake [BECAUSE] int2 [AND] population is a measure of the number of a species in an environment [INFER] int3: as the number of predators in a lake decreases the number of prey will decrease in that lake [BECAUSE] predators eat prey [AND] if an animal eats other animals for food , then the animal will be the predator [INFER] int4: if an animal eats another animal then the animal will be the predator and the other animal will be the prey [BECAUSE] int4 [AND] fish eat insects [INFER] int5: fish are predators to insects and insects are prey to fish [BECAUSE] int3 [AND] int5 [INFER] int6: as the number of fish in a lake increases the number of insects in that lake will decrease [BECAUSE] int6 [AND] if something decreases in number then there will be fewer of that something [INFER] int7: if the number of fish in a lake increases there will be fewer insects in that lake
