Answer:
Carnivores
Step-by-step explanation:
There are five basic components without which an ecosystem could not survive -
- energy,
- mineral nutrients,
- water,
- oxygen, and
- living organisms.
The entire energy of an ecosystem comes from the sun, thus sun is essential. Similarly , water and climate is also essential. Water provides the free electron during the photosynthesis reaction and fair climate ensures visibility of sun. Producers produce food which is consumed by herbivores , thus both plants and herbivores are important. Plant takes nutrients from soil thus soil is also important. Now if carnivores are removed from the ecosystem, then herbivores will die naturally and their dead bodies will be decomposed by the decomposers.
Thus, without carnivores an ecosystem could probably survive.
