Hello. You did not put the excerpt to which this question refers, which makes it impossible for the question to be answered. However, I can help you by showing you what participles are and how you can find them in the text you have.
Participio is a term that refers to the way to use a verb, attributing it to functions of different grammatical classes. In this case, a verb can be used as a noun, an adjective or even an adverb.
The participant can be of the present type (in this case, the verb will always end with "ing"), or of the past type (in this case, the verb will always end with "ed", "d", "t", "en "or" n ").
