Ch. 10: Photosynthesis (Ps) • Ps is the process that converts solar energy into chemical energy – Directly or indirectly, Ps nourishes almost the entire living world – Ps occurs in plants, algae, certain other protists, and some prokaryotes • Autotrophs sustain themselves without eating anything derived from other organisms – Autotrophs are the producers of the biosphere, producing organic molecules from CO2 and other inorganic molecules – Almost all plants are photoautotrophs, using the energy

Thunderstorm of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. Since opposites attract, which is common and that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge
