The Great Barrier ReefÊ teems with life. From algae to a grey reef shark, the animals in this book are linked together in a food chain. Each one of them needs the others in order to live. Find out what eats what in the ocean!
Seeds to mouse to weasel to owl. That's a simple food chain in a deciduous forest. Food chains are fascinating! Every environment has factors that affect the flow of energy in its food chains--all the way up to you! This beautifully illustrated series explores the plants and animals that live in each ecosystem, the adaptations its plant and animal have, and how the flow of energy creates the food chain links. Discover what's for dinner in the food chains and webs in each environment with easy-to-read text, sidebars, and back matter. Looking Glass Library is an imprint of Magic Wagon, a division of ABDO Group. Grades P-4.
It's beach day, and the whole class is excited. Everyone except Arnold and Keesha, that is. They forgot their report on two beach things that go together. All Arnold and Keesha have is a tunafish sandwich and some smelly green pond scum. What could those two things possibly have in common? "The best way to learn about something is to jump right in," Ms. Frizzle announces. A second later the bus dives right into the ocean! Come on an underwater adventure and learn about food chains.
Introduces the rain forest food chain, describing the parts of a food chain and identifying some of the consumers, producers, and decomposers in the rain forests around the world.
Against the background of global market liberalization, increasing consumer awareness and concerns and the spreading of complex technology, new ways to produce, distribute and consume food are evolving. The organization of agricultural production and distribution systems need to adapt, including the development and maintenance of sustainable business relationships between farmers, food processors and grocery retailers. While agricultural value chains have been promoted for decades, more attention is needed on how to enable economic agents to develop lasting relationships and trust within value chains. Using qualitative and quantitative empirical results, Agri-food Chain Relationships offers an insight into the sustainability of current agribusiness relationships and discusses how these may be improved. Theoretical foundations for analysing agri-food chain relations are considered alongside case studies of different countries, food chains and chain stages regarding the issues of sustainable relationships and trust.
An Interactive Journey up the Food Chain Animals are adorable, but they also have a wild side. Many hunt to survive—and must avoid being hunted. This kid-friendly introduction to nature’s predator-prey relationship spotlights several amazing examples. Wildlife photographer Stan Tekiela presents spectacular photos of real critters in their natural habitats, while author Ryan Jacobson explores their most interesting hunting and eating habits. How do snakes catch their meals? Why do mosquitoes feed on blood? Children learn about each animal and then get to guess, What Eats That? With every turn of the page, the predator becomes the prey as the answer is revealed! Stan and Ryan’s first book together won a Mom’s Choice Award. This follow-up is perfect for any child who loves animals or appreciates nature.
Reflecting the recent surge of activity in food web research fueled by new empirical data, this authoritative volume successfully spans and integrates the areas of theory, basic empirical research, applications, and resource problems. Written by recognized leaders from various branches of ecological research, this work provides an in-depth treatment of the most recent advances in the field and examines the complexity and variability of food webs through reviews, new research, and syntheses of the major issues in food web research. Food Webs features material on the role of nutrients, detritus and microbes in food webs, indirect effects in food webs, the interaction of productivity and consumption, linking cause and effect in food webs, temporal and spatial scales of food web dynamics, applications of food webs to pest management, fisheries, and ecosystem stress. Three comprehensive chapters synthesize important information on the role of indirect effects, productivity and consumer regulation, and temporal, spatial and life history influences on food webs. In addition, numerous tables, figures, and mathematical equations found nowhere else in related literature are presented in this outstanding work. Food Webs offers researchers and graduate students in various branches of ecology an extensive examination of the subject. Ecologists interested in food webs or community ecology will also find this book an invaluable tool for understanding the current state of knowledge of food web research.
