Still Water Animals
Animals living in aquatic habitats have diversified and evolved through time. They eventually occupy ecological niches available in the ecosystem. Three regions exist in a freshwater environment: profundal, pelagic, and benthic. Get more information on each of these regions and how these regions led to the varying niches that freshwater animals eventually occupied...
Animal Water Regulation
Animals adapt to their environment in aspects of anatomy, physiology, and behavior. This tutorial will help you understand how animals adapt to their habitat. For instance, how animals thrive in aquatic habitat and are able to overcome osmosis. It also sheds light on the reasons animals adapt...
Digestion and Absorption of Food
The gastrointestinal system breaks down particles of ingested food into molecular forms by enzymes through digestion and then transferred to the internal environment by absorption. Find out more about these processes carried out by the gastrointestinal system through this tutorial...
Amphibians & Early Reptiles
Obtaining air outside an aquatic environment required species to acquire suitable adaptations, and this was the case of amphibians. However, they were limited by their inability to inhabit drylands. Apparently, the early reptiles were able to do so. To learn more about the evolution of amphibians and reptiles, read this tutorial...
Early Mammals on Earth
The Earth's ecosphere was rapidly changing and throwing up a wide range of ecological niches that new adaptive organisms, such as mammals, could fit into. Eventually, every continent of the planet had its own variety of mammalian organisms and their own unique evolutionary chain and direction. Learn more about the early mammals that roamed the Earth alongside other organisms, such as reptiles, fish, and birds...
