Hi! Well a population is a group of organisms that are the same species and live in the same area and they interact with each other! A community is where different populations of species live in the same area and interact with each other!
These are called perennial plants. Annual plants go through their entire life process within a single year and stop existing, meaning they can't produce fruit every year.
The symbiotic relationship in which both participating parties benefit is called mutualism. When one organism benefits and the other organism is harmed it is called<span> parasitism.</span>
