Biology

Biology is the science with the most moving parts, most of them alive and few of them cooperating. This shelf covers how living things work and how they get along, or fail to: cells and what runs them, species and how they adapt, and the ecosystems where everything is somebody's lunch.

The strongest vein here is ecological relationships. Symbiosis in every biome you can name, from rainforest to tundra; food chains and food webs traced link by link; producers, consumers and decomposers each given their due. Alongside it sit the mechanism guides, covering photosynthesis, osmosis, enzymes and genetics, written to explain what actually happens rather than to decorate a diagram.

The featured guides above collect the big ecosystem references. For anything else, the article list runs from adaptations to zoology. One standing note: articles about the human body here explain how it works and never tell you what to do about yours; that conversation belongs to a professional who can see you.
