Biomes. A large geographical region with a specific range of temperatures and precipitation, and the organisms that are adapted to those conditions of temperature and precipitation. Adaptations to Meet Challenges of Life on Land. Challenges of Life on Land vs. Water. Adaptation to Meet Challenge . Air much less buoyant than water so must move against gravity. Limbs develop;. skeletal and muscle systems become stronger. Frogs capable of absorbing water from moisture at soil surface or on wet or dewy vegetation or rocks.. Accomplished by assuming water-absorbing posture with hind legs splayed and ventral surface of legs and abdomen pressed to substrate. . Amphibians are eukaryotic, heterotrophic vertebrates. They have thin, smooth, moist skin. Some of them have fish-like scales and none of them have claws.. They are ectothermic (coldblooded).. They have external gills and lungs..
