- Put the food resource at the arrow's tail and the consumer at the point. Say which resource part: leaves, sap, pollen/nectar or an animal.
- A feeding arrow tells us about some matter and chemical energy passing through feeding. It does not tell us an amount or what must happen to a population.
- Sunlight brings energy to producers. Matter can cycle through organisms, air, water and soil. Energy changes form and can spread as heat; it does not cycle back from soil into sunlight.
- Choose a model change. Ask what could happen, why, and what else you need to know.

You choose whether your explainer is for yourself, private practice or a willing person. A title is optional. You do not need a device, handwriting, a full web or a public audience. An adult can read or write your choices and check them with you. Your ideas, an adult's making and a plan for later stay named honestly. There is no required home return.
Days 25/30 use new source models kept separate until then. Try one component now; another can wait. An unfinished response is not a failed response.
