Ecology Lesson

If a scientist in New Zealand was studying how a group of herbivores interacted with a group of omnivores, and all of their abiotic surroundings, what level of ecology would she be studying?

Ruby-throated hummingbirds live in woodland areas, but also frequent gardens where flowering plants are plentiful. They hover to feed on flowers, nectar, and sap. During this floral feeding process, the birds pollinate many plants. These tiny birds are omnivores, sometimes feeding on insects and spiders.

What is the PRODUCT of the process used by producers that is passed on as energy throughout an ecosystem?

If there are 100 KJ of energy available at the secondary consumer level, how many KJ of energy are available at the producer level?
