A muddy puddle might not look like a habitat, but peer inside with a microscope and it’s home to a world of microscopic creatures. In this book, readers will explore the smallest of habitats and ecosystems. What lives on and in a rotting tree stump? Who makes their home in a compost heap? And is it true that your body is actually a microhabitat? The book includes critical thinking questions, activities and experiments, and it is supported with numerous free downloadable worksheets and resources.
