The Basic Needs of Living Organisms
Water
• Transports nutrients to cells and carries waste products away
• Regulates body temperature in humans• Needed by plants
Shelter
• Needed to make life more comfortable.• Climate control• Protect from harm
Air• Filled with gases such as nitrogen,
oxygen, carbon dioxide and other gases.• Oxygen needed by organisms for
respiration• Nitrogen is needed for building structural
proteins in plants. Also controls combustion rate of oxygen.
• Carbon dioxide needed by plants for photosynthesis
Minerals
• Nitrogen, phosphorus, potassium, iron, zinc, manganese are minerals found in plants.
• We receive these minerals through the food chain.
Food
• Plants and animals provide carbohydrates and fats for energy and normal body functions
Decomposers
• Decomposers include bacteria and fungi• These organisms recycle organic material
to keep the soil fertile. • This allows more plant growth which
supports all ecosystems.
