If producers were removed from an ecosystem there would be no more food web.
Nothing would happen at all.
All organisms that are not producers are known as discomposes. This is in fungi.
Producers are essential to all ecosystems because most our our meals are linked to producers. For ex. Beef (Cows) eat corn if they are unlucky, and if they're lucky they get to eat grass. Both corn, and grass are producers. If no producers were not available, animals, and humans would wipe out.
All life would end
we would all die, mwuhahahahaha
All producers would die out and eventually so would all organisms.
Consumers would also die; they depend for producers for food
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.
Extinction
So will everything else.
If all producers were eliminated from an ecosystem, there would be no source of food or energy for other organisms. This would result in the collapse of the entire ecosystem as consumers, decomposers, and all other organisms in the food chain would not be able to survive without the energy and nutrients provided by producers through photosynthesis.
The consumers would die of starvation.
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.
It depends on what producers you're referring to. In some cases, producers in a community may be completely independent of the other organisms. But in most cases, the producers reside at the bottom trophic level, providing energy for the primary consumers, secondary consumers, and on. Upon removal, the food web would collapse, causing extinction, migration, or possibly evolution. Think of it this way: all the different levels of organisms are stacked on top of each other as blocks. The primary producers would be the bottom block. Now remove that bottom block and suddenly the succeeding blocks are unstable and will then fall without the support of the producers.
The number of primary consumer will increase and it will eat producers which utlimately leads to distruction of all live forms on the earth

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.
