  3. 3. How do Carnivorous plants get their energy?• They get their energy the same way the other plants do... Photosynthesis

  5. 5. What types are there?
  6. 6. Pitfall Traps(pitcher plant) The pitcher plant is basically a slippery leaf wrapped into a tube shape that contains a pool of digestive enzymes at the bottom.

  8. 8. Most Pitfall Traps have the opening on the top of the plant, the Cobra Lily has an opening on the bottom. When an insect flies into it, it has “windows” that let light in but not insects out. The insects are attracted to thePitfall Trap light but cant get out.(Cobra Lily)

  10. 10. Fly Paper traps (sundew) Fly Paper traps are coated with a sticky substance called “mucilage". When an insect lands on the plant it sticks to it, after a while the plant will curl around it and digest it.

  12. 12. Snap traps(Venus fly trap) As you can see the Venus Fly Trap has small trigger hairs on the inside, so if an insect lands on it and triggers only one hair and flies off its lucky but if it triggers more than one it will cause its own doom.
