🌿 Animals & Plants
Five micro-lessons · about 36 minutes in total
Photosynthesis, pollination, evolution, food webs and the great migrations. Five lessons, about 36 minutes in total — read one at a time; each stands alone.
The five lessons
1. Photosynthesis: The Real Engine
Sunlight turned into sugar and oxygen — the reaction that runs almost every food chain.
2. Pollination: The Sex Life of Flowers
Petals are advertising — and most of our food crops take the matchmaking.
3. Evolution by Natural Selection
The one idea that makes every species in the world suddenly sensible.
4. Food Webs and Keystone Species
Why the pyramid of energy leaves room for only a few tigers — and why some small species hold everything.
5. The Great Migrations
Terns pole-to-pole, godwits nonstop for days — and the senses that navigate it.
