These days, ecologists tend to be more focused on interactions and sometimes forget the importance of the big picture. I expect you to know the characteristics of the major biomes presented in the book. Most nutrients held in the biomass. Dominated by broad-leaved evergreen trees. More species of plants and animals live in tropical rainforests than all other biomes combined.
Many animals migrate to rivers or rain forests in the dry season.
Like savannas, subject to periodic burning, often with human intervention. Much human impact, far more than rain forests. Often transition between forest and prairie or forest and desert. No sharp line between tropical dry forest and tropical savannas. Have a wet and dry season, but wet season is usually shorter than the dry.
