* Energy Pyramid: An energy pyramid shows how energy flows through an ecosystem. It's organized into trophic levels, with producers at the base and consumers above.
* Producers: Plants are producers, making their own food through photosynthesis.
* Primary Consumers: Herbivores are primary consumers, eating plants.
* Secondary Consumers: Carnivores or omnivores that eat herbivores are secondary consumers.
* Tertiary Consumers: Carnivores that eat other carnivores (secondary consumers) are tertiary consumers.
Golden lion tamarins are primarily insectivores, meaning they eat insects. Insects, in turn, eat plants, making them primary consumers. Because the tamarin eats insects, it becomes a secondary consumer in the energy pyramid.
However, it's worth noting that golden lion tamarins are omnivores and also consume fruits and small vertebrates. This means they can sometimes occupy a higher trophic level (tertiary consumer) depending on their diet.
