Biology / Unit 11 Bio 2593 short lesson, about 20 seconds
"Carnivorous Plants Eat Insects Instead of Photosynthesizing"
Captions available
The idea
Picturing a carnivorous plant as living off insects overstates a real adaptation — prey supplies supplementary nitrogen, per Bio 2591, while photosynthesis supplies energy.
In practice
A sundew deprived of insects still survives and photosynthesizes, though it grows slower in nitrogen-poor soil without that supplement.
Where people slip
This entry states the popular assumption — Bio 2595 gives what prey supplies versus what it does not.
