you guys how come animals and decomposers depend on light for their energy? :S isn't that just plants?

--- Quote from: aangel42 on June 08, 2010, 11:13:32 am ---nope indirectly all organisms depend on light for energy, because we eat plants, or animals that have eaten plants. and all plants require energy (from sunlight) to photosynthesize and produce food
think about it, if there were no plants, primary consumers would die out, then secondary would, then tertiary would, then we would!
get it?

Q5: There are loads more chloroplasts in the pallisade mesophyll cell than normal, so it must be that.
Q18: Obviously D, lungs, because they oxygenate deoxygenated blood and pass this oxygenated blood to the pulmonary vein and into the left chamber.
