Carnivorous Plants
Biology 11
Photosynthesis, yes but…


Carnivorous plants still make their own
food by the process of photosynthesis
But they supplement their “diet” with
insects and other small invertebrates
(no backbone) and on occasions even
vertebrates (small frogs, etc)
Why?


They usually live in habitats that are
very poor in nutrients (especially
nitrogen)
Nitrogen is essential in the making of
amino acids that make up the proteins
and nucleic acids that make up DNA
(genetics)

What must a plant be able to do to be considered
carnivorous?
What do all green plants contain (all
photosynthetic organisms) that allows them to
make their own food through photosynthesis?
Compare and contrast the food items and methods
of capturing them in the three types of plants
mentioned.
What kind of habitat do these organisms live in
and what would be some potential threats to these
habitats?
