a pheromone is a chemical that triggers a natural behaviorial responce in another member of the same species. insect-eating plants use the same pheromones as bugs so they use them to attract insects to eat. by the way it's bad for you to use WikiAnswers to answer science questions out of your text book.
Pheromones are a chemical produce by an animal or insect. It is influenced by the behaviour of the insects often a result of an attraction of the opposite sex.
No. The closest we come to that are a few insect eating plants like the venus fly trap.
The pitcher plant The sun dew The venus fly trap
a carnivore if it doesn't eat vegies/plants either and a omnivore if it eats both insects and vegies/plants
The parts they leave are just the undigestible ones, like the exoskeleton, making it look like the insect's untouched.
Insect eating plants normally have modified leaves in order to trap insects - such as the "trap" in the Venus Flytrap, the "pitcher" of a Pitcher Plant and the sticky hair covered leaves of a Sundew. What they all have in common though is the ability to produce digestive enzymes in order to break down the insect body and facilitate digestion of contents the insect; the exoskeleton is not digested.
On advantage to being an insect that only eats plants is the fact that you don't have to hunt your food supply. Insects that have to look for food may have a terrible time getting their prey.
it will stop you from eating poisonous plants
It strongly depends on the specific bug. Take bees for an example, bees strongly rely on the vibrant colors of flowers and other plants to collect. Other insects such as ants depend on pheromones and scents. So, just because you have 2 insects doesn't mean they are the same; they both have their own unique attributes.
Because insect eat plants, some plants evolved in response into poisonous or carnivorous species.Coevolution is just used to describe an organism that evolves in response to another.
Anti pest such as Urea, can kill insect pests. but urea can decrease the fertility of soil.
These are plants which eats insects that lands on them.
