The best answer I've heard is that the food chain would collapse. How long can you go without eating? We would be a rather grouchy planet in a few days and would be likely to die from food wars (that would be the primary affect on humans as opposed to other animals). Many suggest running out of oxygen but the atmosphere is huge (About 80% of the total mass of the atmosphere is contained in the first 6-7 miles over the surface of the earth) and contains 20% oxygen. Animals primarily inhabit the surface of land (plus a good bit of ocean creatures) so they are not likely to be able to consume all the oxygen before starving. I don't think there is enough biomass to account for the excess oxygen but somebody could crunch the numbers to be sure. Some suggest the decaying matter would consume the oxygen but the wood mass (trees and wood structures) across the earth contain millions of tons of carbon and would take years to rot - we would starve well before that.
then all of the plant eating animals would soon die and then the carnavors would start to eat the other carnovors the soon everything in the world would soon die off and the world would soon end
Yeeeah...um... we would all perish a fatal death. Plants produce the oxygen that we breathe and we can't live without them.
There would be no oxygen killing any living thing on earth and turn it into a baron planet
Life as we know it would cease.
Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
Flowers are part of the reproductive cycle of plants therefore they are not plants per se.
All plants, some protists, bacteria and blue green algae uses the sun to make photosynthesis. Plants use photosynthesis to create energy that then makes sugar for nutrient.
Some characteristics of all plants are:Cells of all plants have a cell wall.Plants make their own food.They need sunlight, some more than others.
All plants need water.
no
The snake would soon die. Snakes are part of the web of life. They eat smaller creatures that eat plants and would die if all the plants died.
all the plants and animals died
If all Plants died, all the animals would die. Herbivores eat plants, Carnivores eat the herbivores and,that preatty much explains it. There is also the cycle of energy if a producer gets eaten by a primary consumer that consumer would be eaten by the secondary consumer until it reaches the tertiary consumer.
If all rice plants were to die then it would affect many animals. If rice plants were wiped out then the local ecosystem would be devastated.
none they all died
Dinosaurs did not die out because of plants. They died out because of a lack of plants after an asteroid impact blocked out sunlight for months or years. With all the plants dead, the dinosaurs starved.
people died and plants shhrivelled up all the people that died were called bob
they would die too
we would die, too
the forest never sleeps. if the forest sleeps all the creatures and plants would have died.
because when the metiorite hit earth, all plants died, so the plant-eaters could not eat, then the carnivoirs that are left could not eat because all tye plant eaters died you see?
