Question

which of the following are needed by all living things?
water, oxygen, food
water, nutrients, energy source
rain, nutrients, sunlight
water, oxygen, energy source

Explanation:

All living things need water for various physiological processes, nutrients to build and repair tissues and for metabolism, and an energy source to fuel life - sustaining activities. While oxygen is needed by most aerobic organisms, some organisms are anaerobic and don't require it. Rain is not a fundamental requirement for all life as some organisms live in arid regions or in water bodies where rain is not relevant in the same way. Sunlight is not needed by all organisms as there are deep - sea and cave organisms that rely on chemical energy sources.

Answer:

water, nutrients, energy source
