If there were not any plants then the herbivores would die.Then the carnivores will die because they won't have any herbivores left.And we would die then.Also without plants we can't eat them and we need the plants.Plus we can't make some things like medicine,clothing,shelter.
If all the plants die,there will be no oxygen.and without oxygen the humans cannot breathe without it.
the plants will not get the soil and without the plants humanbeings can't live
The plant would lose its color and eventually start to wither.
what would happen to plants nutrition if plants did not have roots
Without the sun, Earth would be in darkness except for minimal light from small stars and the moon. Plants would not survive due to lack of sunlight. Without plants animals would not have food and would also die.
Photosynthesis in plants cannot occur without water.
They will die if they will die we will also die.
Well if there were no oxygen then all animals would probably die except plants because all they need is carbon dioxide plants would die without us as plants need us to inhale the oxygen they make then exhale the carbon dioxide that they need. our relationship with plants is interdependant meaning we could not survive without each other
Plants and trees 'breathe' nitrogen and emit oxygen. We as humans do exactly the reverse. So we need plants to be able to keep on breathing. Plants of course also provide us with food (and feed the animals that feed us). So without plants we would very quickly have a very serious foodsituation.
To people, without nitrogen, their brains will burst (seriously). Same thing will happen to animals, and to plants, it will die.
