What are four things organisms need to survive?

1. Energy: Organisms need energy to perform various life functions, such as metabolism, growth, reproduction, and movement. Energy can be obtained from food or through photosynthesis in plants.

2. Water: Water is essential for many physiological processes, including transporting nutrients, regulating body temperature, and participating in chemical reactions.

3. Nutrients: Nutrients are substances that provide essential elements and compounds for growth and development. They include carbohydrates, proteins, fats, vitamins, and minerals.

4. Oxygen: Most organisms require oxygen for cellular respiration, which is the process by which energy is released from organic compounds.
