Studying ecology

i know most of the general things about the ecology chapter since it was in my grade 12 curriculum. i am unsure if I should study it again in detail or not,
is ecology questions asked frequently or is a general idea and key terms more than enough?
thank youu :smiley:

Hi! I think whatโ€™s come up in past questions is mostly to do with the definitions of the different terminology, and their application โ†’ community, population, habitat. Definitely make sure you know the different types of speciation, symbiotic relationships and competition, mutations and how that leads to evolution of organisms. Itโ€™s also good to know the trophic levels and how biomass is efficiently transferred between them and the calculations involved. Itโ€™s good to memorise the nitrogen cycle and carbon cycle too
