Introduction
You are about to embark on a journey to an ecosystem. An ecosystem is a natural unit consisting of plants, animals and micro-organisms which share the same habitat and function together with all of the non-living physical factors of the environment. Each ecosystem has varying temperatures, amounts of moisture and light, soils, plants, and animals. As you progress through the task, reflect on your present knowledge of the coexistence of animals, plants, and humans in specific climates around the world.
