Are there any good resources for people who may want to pursue ecology?

My advice would be to go for it!

Math and chem can be hard but just lean on the resources that are there to help you a lot. (Study groups, tutoring centers, etc.)

You can definitely do well in those classes if you put in the effort.

Worth noting: there’s a good book by the biologist E.O. Wilson called letters to a young scientist and he talks about how he didn’t even learn a lot of the basic math that other scientists have until he was already a professor and how struggling with that skill shouldn’t stop anyone from pursuing a career in science (or relating to it).
