Answers
Answer:
1) Pitcher plant derives nutrition just the way any other plant does . It takes water and minerals from the soil and food by photosynthesis. But the soil in which it grows doesn't has nitrogen so it uses the pitcher for killing small insects and then digesting them to derive nitrogen from the animal
2)The organism that grows on the body of another organism and derives nutrients from it is known as a parasite. The organism that obtains nutrients from the dead or decaying organic matter is called saprotroph.
3) Symbiotic relationships are a special type of interaction between species. Sometimes beneficial, sometimes harmful, these relationships are essential to many organisms and ecosystems, and they provide a balance that can only be achieved by working together
