Consumers would starve very quickly.
All producers would die out and eventually so would all organisms.
Consumers would also die; they depend for producers for food
Extinction
eventually all of the consumers that eats those plants (producers) would die off or move to a different habitat. But this will most likely not happen because it would be very hard to permanently destroy all of the producers in that biome.
The consumers would die of starvation.
So will everything else.
The thing that gets eaten by the producer will just increase because no one eats them
the population of producers would grow and grow until it dies from robbing the world of nutrients
Then nobody would have any kind of plant life!!!
The most likely thing that will probably happen if someone killed all the producers in an area is that they would have to come in from another area. Whenever there is a higher demand, people will naturally go there to fill the void.
if the producers disappeared the other animals such as the primary, secondary,and tertiary consumers and the decomposer would not have anything to eat because the producers would not exist so all the other animals would become extinct.
there will be a imbalance in nature
