Adaptations

• Any organism must be adapted to its environment to survive, with examples including polar bears having thick fur to withstand cold and owls having big eyes to see in the dark.
• Adaptations can be categorized into structural, behavioral, and functional groups.
• Structural adaptations are the physical features of an organism, such as its shape or color.
• Behavioral adaptations are the way an organism behaves or acts, such as the flapping of elephant ears to cool down or swallows migrating to warmer countries during the winter.
• Functional adaptations are the processes going on inside an organism's body, such as their metabolism or reproductive system.
• Desert animals conserve water by producing very little sweat and only small amounts of concentrated urine.
• Camels accumulate lots of fat in their humps which they can then break down later to release water.
• The brown bear, also known as ursus actos, is found across the northern latitudes of America and Eurasia and has a diverse and variable diet including plants, fungi, fish, invertebrates, and mammals like deer.
• The brown bear is adapted to live in its environment by having thick fur, a diverse and variable diet, and the ability to hibernate.
• Extremophiles are a group of microorganisms like bacteria or archaea that are adapted to live in extreme environments such as hot springs, salt lakes, and deep sea vents.
