The document describes how the environment sustains life through providing basic needs like food, water, air, shelter and space. It defines key terms like ecosystem, habitat, food chain and explains the roles of humans as resource users and decision makers who can prevent waste. Living things obtain nutrients from food sources in their habitat and energy is transferred between organisms through food chains within ecosystems. Sustainable practices aim to assure that resources and development meet long term needs without damaging the environment.
