Biomes and Ecosystems (Gareth Stevens Vital Science: Earth Science)
$14.05
An ecosystem consists of both living (biotic) and nonliving (abiotic) systems. For example in "a forest ecosystem, biotic components include everything from microscopic bacteria to delicate mosses to trees that may have first sent roots into the soil more than one hundred years ago." Everything in an ecosystem works together to make it function as a whole and each biotic and abiotic thing has an effect on the entire system. For example, just take a look at the small honeybee and the effect our environment would be without them! Biomes cover broad areas of the earth, say deserts, mountainous areas, the poles or oceans. A biome can be "defined by the type of climate each biome has and the type of plants and animals that live there.

In this book you will be able to take a close look at the interaction of ecosystems and biomes. You will learn about biotic and abiotic interactions (from the microscopic to the community), habitats, niches, ecosystem diversity, photosynthesis, the food chains, food webs, "energy pyramids," the distribution of consumers in the pyramid, the competition for resources, rainforests, predator/prey relationships, relationships between species (mutual and destructive), the water cycle, the carbon cycle, the nitrogen cycle, humanity's place in these cycles, the greenhouse effect, changes in ecosystems (succession), climate change, how biomes are affected by climate and much more.

This is a very thorough, clear, concise interesting book and the writing from one topic to the next is seamless. The print is small and there is a lot of information packed in these pages. There are numerous informative sidebars, photographs and illustrations scattered throughout the book. In the back of the book is an excellent index a glossary, and additional recommended book, film and web site resources. Do you think you can make a difference in protecting our Earth's resources? This is a good place to start reading about what we have to lose if we don't take care of it!

Que Son Las Redes Y Cadenas Alimentarias? / What are Food Chains and Webs? (La Ciencia De Los Seres Vivos/Science of Living Things (Spanish)) (Spanish Edition)
$25.27
This title is intended for ages 6-12. Text is in Spanish. Sunlight does not go very deep into water so seaweed must grow at the surface where its rays can reach them. Starting with the sun, food chains link together plants and animals in various ecosystems to help them survive. This book describes these connections in a clear manner that children will understand. Fascinating diagrams show children: the connection between herbivores, carnivores, scavengers, decomposers, and themselves; concepts such as energy pyramids, photosynthesis, and consumer hierarchies; and, an entertaining food web game.
