We shift focus on the flow of energy through ecosystems. We look at food chains and food webs and how these are used to illustrate the flow of energy through the ecosystem. We also look at ecological pyramids and the different trophic levels, and how we can draw these pyramids from the food chains and food webs.
Animals develop adaptations to survive in extreme environments and maintain balance, we also look at the how the balance can be disturbed by natural and human factors.
In order for organisms to survive in extreme environments organisms will develop certain adaptations. These adaptations can be structural, functional or behavioural. We look at plants and animals who work in similar ways.
Microorganisms are extremely small living organisms that can be found in many places around us. In this lesson we will study their harmful and useful characteristics.
