ecology master's programs with a background in chemistry?

I recently graduated with a b.s. in chemistry. I was never really that into chemistry, but the school I was attending didn't have another option I was interested in, and I couldn't transfer for financial reasons.

I've always had a passion for ecology, and I was wondering if there's a possibility of going into a master's program in ecology with a background in chemistry.

Also, I do still love chemistry, is there a branch of ecology that uses a lot of chemistry?
