Ch.4 Ecosystems
Chapter 4 is an introduction to ecosystems, habitats and communities - the homes and animals and plants in nature. Just like we live in a house, have a job, and use resources, so do all of the organisms which live in the various regions of Earth. We get to learn all about the different ways animals and plants interact, and then talk about how energy is cycled through the environment in different ways. Did you know that the amount of water on Earth right now is the same amount of water when the Earth began? And it will always be the same forever and ever!
