Their fur them defend themselves what is the verbs and is it past present or future

Hello, Rumblzlyenge. So, let's look at the statement. "Their fur helps them defend themselves." Ok, first, ask yourself, what is a verb? Well, a verb is a word used to describe an action, so what is the action? Defend. Now, I think defend is the only verb, don't you? Next, past, present, or future. "Their fur helps them defend themselves." I would think Present. If it was past, the statement would be: "Their fur helped them defend themselves." If it was future, the statement would be: "Their fur will help them defend themselves." I hope I helped :D
