Plants capture the energy of the sun in photosynthesis and use this to produce biomass. The fate of plants is to be eaten (herbivory) or to die and decompose. The flux of energy into...

Evolution is not perfect. And we are clever. Our solar panels are much more efficient than plants in capturing solar energy
Biomes - e.g. tropical rainforest, savnnes, taiga - are biological communities which are adapted to their regeional climate and which extend over large geographic regions. Which of the following factors does NOT contribute to the worldwide distribution of biomes...
