Volume since it relates to surface area to volume ratio
A frog's lungs don't work that well, but since it's skin is so thin, oxygen and carbon dioxide can pass trough it.
Tapping of geothermal energy
to produce electricity is done on a larger scale compared to the tapping of
the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area
of convection boundaries while geothermal
gradient can be harnessed virtually
anywhere on the earth surface.
Hey! <span>Photosynthesis is a process whereby
plants, some bacteria and a few types of algae convert energy from
sunlight into chemical energy and store it as sugar. The internal fuel
that plants use for survival is created by photosynthesis. Plants require carbon dioxide, water and light energy to synthesize sugar.</span>
