They would die.
It's a simple answer but I hope it's what you were looking for.
Plants are vital for the ecosystem as they produce oxygen through photosynthesis, provide food for animals, and help regulate the climate by absorbing carbon dioxide. Without plants, the food chain would collapse, and the atmosphere would be lacking oxygen, which would lead to a catastrophic imbalance in the ecosystem.
There would be no oxygen therefore no humans or animals.
Humans would die, because plants make our oxygen
the trees give us oxygen so......we would die.
we all die lol Everything that needs oxygen would die. including us, animals, and plants.
Everything that is a heterotroph would die because of no oxygen, including us.
If all the plants die,there will be no oxygen.and without oxygen the humans cannot breathe without it.
If humans killed ALL plants on earth, we would all suffocate. This is because plants convert co2 (carbon dioxide), which is exhaled by all animals, back into oxygen through photosynthesis. If they didn't convert co2, the earth's oxygen supply would depleat and we would fill the atmosphere with co2, and we would have no oxygen.
The earth would eventually run out of oxygen. All animals would eventually die.
there would be nothing giving us oxygen and every living thing would suffocate.
If plants take oxygen as they give out during the day the humen beings and animals were die
we will die because there is no oxygen to breathe in
