Life at the limits - Organisms in Extreme Environments
We are fascinated by the seemingly impossible places in which organisms can live. There are frogs that freeze solid, worms that dry out and bacteria that survive temperatures over 100˚C. What seems extreme to us is, however, not extreme to these organisms. In this captivating account, the reader is taken on a tour of extreme environments, and shown the remarkable abilities of organisms to survive a range of extreme conditions, such as high and low temperatures and desiccation.
One of the greatest scientific feats of our era is the astonishing progress made in understanding the intricate machinery of life. This intensive, 72-lecture course gives you the background and guidance to explore in depth the fundamental principles of how living things work—principles such as evolution by natural selection, the cellular structure of organisms, the DNA theory of inheritance, and other key ideas that help you appreciate the marvelous diversity and complexity of life.
Disney Educational - Bill Nye The Science Guy: Ocean Life
In Bill Nye the Science Guy: Ocean Life, the Science Guy takes a look at the small organisms of the sea, including plankton, kelp, and coral. Although many of these life forms are too small to be seen with the naked eye, their importance to larger organisms is enormous. Bill Nye goes down to the depths to investigate phytoplankton and zooplankton and their place in the ocean food chain. His special guest is marine biologist Karen Montano, who visits tide pools with a group of youngsters for a look at the "nurseries of the sea."
This guide covers the fundamental scientific concepts of ecology as taught in biology and environmental science courses. It offers essays on the levels of individual organisms and their interactions with the environment, and the levels of ecosystems and global ecology, for example.
