What is the probability that the material cycles will be on the dat such as the carbon cycle or nitrogen cycle? Also, how in depth should we know the ecology stuff? Kaplan bb never mentions chaparral, estuary, or eutrophic, but it is in topscore or achiever.

I know that ecology is a topic on DAT, but I wanted to know how often and detailed it is. For example, the weird biomes that are included in acheiver.
