1. How do leaves help a plant make its food?​

Answer 1

Answer:

1. Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.
2. The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
3. The main difference between total parasite and partial parasite is that the total parasite totally depends on the host for its growth, survival, and reproduction whereas the partial parasite depends on the host only for a certain requirement of their life such as water and shelter.
