1 answer

The first organism in an energy pyramid or food chain is a producer. Producers, such as plants and algae, are organisms that can photosynthesize and create their own food using sunlight, water, and carbon dioxide. They form the base of the food chain and provide energy for primary consumers, which are the herbivores that eat the producers.
