🎯 Your mission
Predict it first. Then prove yourself right (or wrong).

Mind = Blown
🌳 Trees can talk to each other through underground fungus networks.
Make a hypothesis first
Predict: what will happen to the plant if you change the water?
What You'll Learn
Predator-prey relationships help keep ecosystems balanced. When prey populations increase, predator populations grow too. When predators reduce prey numbers, predator populations then decline.
