We use the preposition “in” with the verb “to participate”. We don’t usually use “participate on” in English.
We use the preposition “in” when we want to show that something exists in a volume. That could be “in a park”, “in a field” or “in a bottle” or it could be something within some metaphorical boundary like “in a debate”. Let’s look at some examples of participate with the preposition “in”:
