Ans is option C. They both need an energy source in order to survive.
Energy is an absolute necessity to survive on this earth. All living organisms need energy be it anaerobic or photosynthetic. Photosynthetic organisms can make their own food in the presence of sunlight by photosynthesis and harness energy from it. Anaerobic organisms can also make their own food in the absence of sunlight with the help of inorganic molecules like hydrogen sulfide (H2S), ammonia (NH3), sulphur (S) etc.
Its just that anaerobic organism's way of harnessing energy is different from those of aerobes/photosynthetic organisms but they need energy source for sure.
Composite volcanoes. Had this question on apex:)
Porosity<span> is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock. The substance which has the greatest porosity would be the one that would absorb more water and faster. Hope this helps. Have a nice day.</span>
