Are omnivores such as toads, sandhill cranes, and woodchucks primary or secondary consumers and how do you know? Thanks!

I already read that and I couldn't find the answer.
When omnivores are eating plants, they're considered primary consumers. When they eat other animals, they're considered secondary consumers. Check this site for more information.

I looked at that site too. :)
It's just that I'm making a food web for a school project. That means that I have to show every single organism that every single organism can eat.
I run into a problem here:
I have grass on the producer level, a grasshopper on the primary consumer level, and a woodchuck on the secondary consumer level. The woodchuck can eat both the grass and the grasshopper. Is it okay to have an arrow pointing from both the grass and the grasshopper to the woodchuck?
