This informative and beautiful book looks at apex or top predators - animals that are not eaten by other animals in their habitats - and why these animals play a very important role in keeping food chains in balance. Students are introduced to the energy pyramid, which shows that there are fewer top predators than other animals and gives reasons why many of these animals are endangered. Humans, the most powerful top predators, are the biggest threat to these essential endangered animals.
This intriguing book looks at the remarkable abilities of plants and animals, which need to be studied to make our environment more sustainable. People have already used birds as models for constructing airplanes, but there are so many other models that have not been replicated. Living things live at the depths of oceans and at the tops of the highest mountains, harness the energy of the sun to make food, make oxygen from carbon dioxide, walk on water, build structures that are air-conditioned, and make materials stronger than steel without ever polluting or damaging the environment. They have done all the things we wish we could do. This book will make young scientists aware of the super powers of nature and may inspire some to find ways to change the future of Earth!
Animals have become extinct for many reasons. The most famous example, the extinction of the dinosaurs, may have been the result of an asteroid hitting Earth or an Ice Age freezing them to death. Prehistoric mammoths and saber-toothed cats may simply have been hunted to extinction. Today, animals such as elephants, zebras, tigers and leopards, some wolves, and many kinds of primates may still face extinction due to climate change, habitat loss, hunting, poaching, and pollution. This fascinating book introduces and explains the designations of endangerment from extinct in the wild to vulnerable. Children are also introduced to fossils as a way of learning about animals that lived long ago.
