1. They obtain (get) & use resources for energy • Food, oxygen, water • Need these to grow, develop, repair • Autotrophs – Make their own food through photosynthesis (producers) • Heterotrophs – Seek out other food sources (consumers) • Respiration – Breaking down food into energy
2. They respond to stimuli • Stimulus – a change in surroundings that makes an organism react • Response – What the organism does to react to a stimuli
