Humans themselves do not use photosynthesis, but because humans depend on plants, as well as other animals that eat plants, in order to live, no, humans could not live without photosynthesis. Unless plants had another way to make food for themselves, humans could not live without photosynthesis.
Yes they do. Humans eat plants and animals to survive, animals eat plants, plants need photosynthesis to survive and if they didn't conduct photosynthesis then they would die and we wouldn't have the nutrition's to live.
Only plants have it.
Yes
Yes they do they need need oxigen and trees make it in their photosynthesis
of course they can they have been doing that for hundreds of millions of years in remote areas of the earth
1. The plants produce oxygen so we can live from that. 2. Photosynthesis produces a sugar that the plants eat and helps them grow so when they are grown we can get food from them.
Clothing, Oil, plastics, Lumber, bitumen, furniture, As amater of fact without it we would not have anything as photosynthesis is our only usefull link to the suns energy.
Indirectly, yes. We humans eat plants; plants grow and generate energy by photosynthesis, so we need it. Or, we humans eat animals, and the animals eat plants, which use photosynthesis. At some level, our life depends on plants.
Photosynthesis provides food for the producers, which are then eaten by first-order consumers, which may be eaten by second-order consumers, and so on, which are then eaten by crocodiles, which are probably the highest-order consumer in the food web, unless humans are involved. Without photosynthesis to convert light energy into chemical energy in food molecules, there would be no producers or consumers, and no crocodiles (or humans).
yes. no.
no seaweed needs photosynthesis to grow.
yes because without photosynthesis we wouldnt live
of course ...no because the humans and animals lose food

Yes humans can live with out heads if they are an zombie.
you cant live without oxygen
grass we can always live without grass
Yes.
No.
Oxygen and carbohydrates are products of photosynthesis that are important to humans.
No, humans cannot live without establishing a harmonious connection with the ecosystems in the oceans.
