What are atoms? What particles are they composed of? What is relative location and charge of each particle?

Explanation:

an atom is the smallest chemical particle that exists

the are composed of 3 main things

protons

neutrons

electrons

protons and neutrons are located in the nucleus of the atomic structure( centre) and electrons are in shells out of the nucleus

protons are positive charged

electrons are negative charged

neutrons don't have a charge as their charge is too small and considered as nothing so 0

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
