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!
The ocean is full of complex food webs made up of many different animals fighting to stay alive within this massive ecosystem. Carnivores, herbivores, and other classified creatures are introduced within the accessible and age-appropriate narrative, which is presented in a conversational tone and creative way. Popular creatures are categorized separately and given detailed descriptions, which allows readers to expand their knowledge of each animal. Helpful graphic organizers provide additional information. Full-color photographs make this an exciting learning experience for all those interested in expanding their knowledge of the science and webs of marine life.
In Ocean Food Chains, early fluent readers explore the ocean biome and the food chains it supports. Vibrant, full-color photos and carefully leveled text engage young readers as they explore how energy flows through plants and animals in a marine environment. A map helps readers identify the world's oceans, and an activity offers kids an opportunity to extend discovery. Children can learn more about ocean food chains using our safe search engine that provides relevant, age-appropriate websites. Ocean Food Chains also features reading tips for teachers and parents, a table of contents, a glossary, and an index. Ocean Food Chains is part of Jump!'s Who Eats What? series.
"Food chains are fascinating! Did you know all food starts with the sun? Plants use the sun's energy to grow, and then they become energy for animals. Every environment has factors that affect the flow of energy in its food chains--all the way up to you!Discover what plants and animals create the links of food chains and in each environment." -- p. 4 of cover.
Discusses the ocean ecosystem and the role of the sea otter as a keystone species in helping to maintain it, describing the otter's place on the food chain and what would happen if the sea otter were to become extinct.
Explains how coral reef animals get their energy from food chains.
"In Coral Reef Food Chains, early fluent readers explore the coral reef biome and the food chains it supports. Vibrant, full-color photos and carefully leveled text engage young readers as they explore how energy flows through plants and animals on a coral reef. A map helps readers identify major reefs in the world's oceans, and an activity offers kids an opportunity to extend discovery. Children can learn more about coral reef food chains using our safe search engine that provides relevant, age-appropriate websites. Coral Reef Food Chains also features reading tips for teachers and parents, a table of contents, a glossary, and an index. Coral Reef Food Chains is part of Jump!'s Who Eats What? series."
Ocean food chains are very complex and interesting. Learn about who eats whom in the oceans!
"Explains the concept of a food chain and how plants, animals, and humans are ecologically linked." -- T.p. verso.
Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems. In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book: provides a snapshot of the past health of the North Atlantic and compares it to its present status presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level considers the factors that have led to the current situation describes the policy options available for halting the decline offers recommendations for restoring the North Atlantic An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems. This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.
