Can there be a food chain without herbivores and carnivores?

A Food Chain Without Herbivores and Carnivores. Without the herbivores, the producers would be free to grow. Producers don't need the herbivores or carnivores to make their own food and energy. They are self-sustaining, and they can't exhaust their food source.

And as well as if there are only producers and no herbivores or carnivores then producers grow on continuously and there will not be the utilization of it. so there can't be a food chain without herbivores or carnivores.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's
