sentences: large canopies / trees block sunlight from reaching the ground & tropical rainforests contain many large trees ->  sunlight is blocked by large canopies / trees in rainforests  sunlight is blocked by large canopies / trees in rainforests & forest canopies blocking sunlight decreases the availability of sunlight on the forest floor ->  tropical rainforest floors are low in availability of sunlight  as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase1 & a plant requires sunlight for photosynthesis ->  a low availability of sunlight has a negative impact on plants  tropical rainforest floors are low in availability of sunlight & a low availability of sunlight has a negative impact on plants ->  low availability of sunlight has a negative impact on plants in tropical rainforest floors  as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase & larger means greater / higher / more / increase in size ->  large leaves increase a plant's ability to absorb sunlight  a leaf is a part of a green plant & a leaf absorbs sunlight to perform photosynthesis ->  a plant absorbs sunlight with its leaves to perform photosynthesis  a plant absorbs sunlight with its leaves to perform photosynthesis & as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase2 ->  a plant must absorb sunlight with its leaves to survive  as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase0 & as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase3 ->  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  a plant must absorb sunlight with its leaves to survive & 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 ->  increasing a plant's ability to absorb sunlight with its leaves has a positive impact on that plant's survival  large leaves increase a plant's ability to absorb sunlight & increasing a plant's ability to absorb sunlight with its leaves has a positive impact on that plant's survival -> sunlight is blocked by large canopies / trees in rainforests0: large leaves have a positive impact on a plant's survival by increasing that plant's ability to absorb sunlight  sunlight is blocked by large canopies / trees in rainforests0 & an adaptation / an ability has a positive impact on an animal 's / living thing 's survival / health / ability to reproduce -> sunlight is blocked by large canopies / trees in rainforests1: large leaves are a kind of adaptation for absorbing sunlight  sunlight is blocked by large canopies / trees in rainforests1 & low availability of sunlight has a negative impact on plants in tropical rainforest floors -> plants on tropical rainforest floors grow large leaves due to the low availability of sunlight
