An organism that is the source of all food in an ecosystem is called a producer. A consumer gets its energy by feeding on other organisms.
If all herbivores are killed in an ecosystem ultimately all life will die because there is no food source for carnivores
Kinda, a producer provides food for all the heterotrophs in an ecosystem, a heterotroph being any organism that consume other organisms for energy. However, sunlight provides food for the producer, so indirectly sunlight provides food for an ecosystem.
The trophic level that contains the organisms that are the source of all chemical energy used in an ecosystem is called the producer level. This level contains the organisms that can make their own food.
