Question: A tropical rain forest contains many tall trees. Smaller plants with large leaves grow at the base of the tall trees. The large leaves are most likely an adaptation of the plant due to which condition?
Answer: lack of sunlight
Hypothesis: plants on tropical rainforest floors grow large leaves due to the low availability of sunlight
Supporting facts: sent1: a required resource being low in availability has a negative impact on the something that requires that resource sent2: an adaptation / an ability has a positive impact on an animal 's / living thing 's survival / health / ability to reproduce sent3: the decrease of something required by an organism has a negative impact on that organism 's survival / that organism 's ability sent4: an adaptation is an adaptive feature sent5: the leaves of a plant tilt towards the direction of sunlight sent6: as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase sent7: a plant requires sunlight for photosynthesis sent8: tropical rainforests contain many large trees sent9: adaptation has a positive impact on the population / the survival / the reproduction of a species / of individual organisms sent10: a plant is a kind of living thing sent11: to receive sunlight means to absorb sunlight sent12: if a living thing must do something to survive, then increasing that living thing's ability to do that something has a positive impact on that living thing's survival sent13: intensity of sunlight is similar to amount of sunlight sent14: a leaf is a part of a green plant sent15: a plant requires photosynthesis to grow / survive sent16: larger means greater / higher / more / increase in size sent17: a leaf absorbs sunlight to perform photosynthesis sent18: large canopies / trees block sunlight from reaching the ground sent19: photosynthesis means producers / green plants convert from carbon dioxide and water and solar energy into carbohydrates and food and oxygen for themselves sent20: a leaf performs photosynthesis / gas exchange sent21: photosynthesis is a source of / makes food / energy for the plant by converting carbon dioxide, water, and sunlight into carbohydrates sent22: adaptations are used for survival sent23: darkness has a negative impact on photosynthesis sent24: adapting is when a living thing responds to a change in an environment sent25: forest canopies blocking sunlight decreases the availability of sunlight on the forest floor
Reasoning: [BECAUSE] large canopies / trees block sunlight from reaching the ground [AND] tropical rainforests contain many large trees [INFER] int1: sunlight is blocked by large canopies / trees in rainforests [BECAUSE] int1 [AND] forest canopies blocking sunlight decreases the availability of sunlight on the forest floor [INFER] int2: tropical rainforest floors are low in availability of sunlight [BECAUSE] a required resource being low in availability has a negative impact on the something that requires that resource [AND] a plant requires sunlight for photosynthesis [INFER] int3: a low availability of sunlight has a negative impact on plants [BECAUSE] int2 [AND] int3 [INFER] int4: low availability of sunlight has a negative impact on plants in tropical rainforest floors [BECAUSE] larger means greater / higher / more / increase in size [AND] as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase [INFER] int5: large leaves increase a plant's ability to absorb sunlight [BECAUSE] a leaf is a part of a green plant [AND] a leaf absorbs sunlight to perform photosynthesis [INFER] int6: a plant absorbs sunlight with its leaves to perform photosynthesis [BECAUSE] int6 [AND] a plant requires photosynthesis to grow / survive [INFER] int7: a plant must absorb sunlight with its leaves to survive [BECAUSE] a plant is a kind of living thing [AND] if a living thing must do something to survive, then increasing that living thing's ability to do that something has a positive impact on that living thing's survival [INFER] int8: if a plant must do something to survive, then increasing that plant's ability to do that something has a positive impact on that plant's survival [BECAUSE] int7 [AND] int8 [INFER] int9: increasing a plant's ability to absorb sunlight with its leaves has a positive impact on that plant's survival [BECAUSE] int5 [AND] int9 [INFER] int10: large leaves have a positive impact on a plant's survival by increasing that plant's ability to absorb sunlight [BECAUSE] int10 [AND] an adaptation / an ability has a positive impact on an animal 's / living thing 's survival / health / ability to reproduce [INFER] int11: large leaves are a kind of adaptation for absorbing sunlight [BECAUSE] int11 [AND] int4 [INFER] int12: plants on tropical rainforest floors grow large leaves due to the low availability of sunlight
