One of the following challenges that various animals adapted to from a water dominant environment to a terrestrial environment is that they protected themselves from drying out. In order to carry this adaptation out and avoid desiccation (a process where organisms lose water to the air), plants developed the adaptation of cuticle; a waxy and protective surface layer that is secreted around the exposed surfaces of a plant. This surface is relatively impermeable which essentially helps avoid water loss from taking place in the plant. Additionally, it prevents them from acquiring different types of bacteria and viruses. Another structure that was adapted to prevent water loss was the stomata, which allows water to diffuse out of the plant when it closes. This adaptation is essential because plants need water to go through photosynthesis in order to produce energy. Animals additionally faced the same challenge as well when evolving onto a terrestrial environment. In order to avoid water loss, amphibians usually stayed within moist surroundings since they needed their skin to be wet, so that oxygen can pass through their skin and help them breathe. They didn’t possess any adaptations capable of letting them survive in a dry land environment due to the reliance of their moist skin needed to perform vital life functions. However, reptiles evolved overcame this challenge with the dry, watertight skin they developed. This adaptation significantly reduced the amount of water
