Answer
-
- All the above are primary requirements of life for a multi-celled organism.
Explanation:
There are three basic classes of nutrients which are essential for multi-celled organisms, these include water, micronutrients (vitamins and minerals), energy-yielding and body-building nutrients. Oxygen is vital for processes that require energy from cellular respiration. Environmental conditions are supposed to be optimum for organisms survival as enzymes and macronutrients are affected by environmental factors like temperature.
