MODEL Ecological Organization 1. Organism: Prairie Dog 2. Population: Prairie Dog Town 3. Community: All the living things that interact on the prairie. 4. Ecosystem: All the living and nonliving things that interact on the prairie.

MODEL Your Ecological Organization 1. Organism: 2. Population: 3. Community: 4. Ecosystem:
