Adaptation in Terrestrial Habitat
Terrestrial habitat denotes the land where all animals and plants live. Terrestrial habitat includes various types of habitats like deserts, forests, grasslands, coastal and mountain regions. Animals and plants develop features or certain habits to help them survive in their habitat, this is known as adaptation. Different creatures show different adaptations in particular habitats.
Terrestrial animals show a wide range of adaptations. Animals that live on land are dogs, cat, monkeys, etc. Some of the adaptations seen in these animals are legs that are strong and muscular, paws have soft pads; these adaptations are seen in most of the terrestrial animals.
Plants in the terrestrial habitat are adapted to the dehydrating land environment; they have developed new structures and reproductive mechanisms. Most of the plants are dependent on moist and humid weather conditions but many of them have adapted to more arid and dry climates by developing resistance and tolerance to surrounding conditions.
Alteration of generations is one on the adaptations shown by terrestrial plants where the life cycle of the organism has both stages of haploid and diploid stages. Terrestrial life for plants gives significant challenges for plants that include potential factors like desiccation, radiation that are mutagenic from the sun and the lack of buoyancy of water.
Terrestrial animals are those animals which live on land entirely. Some of the adaptations in terrestrial habitat of animals are the development and modification of foot; bipedal locomotion, development of head; lungs etc.
Feet of terrestrial animals are modified in the following ways:
- The exhibit pentadactylity where the fingers are 5 in number and they are used for walking, climbing, running and grasping proposes. The fingers bear claws.
- They show plantigrade locomotion where the palm and sole rest on the ground. Examples - bear and baboon.
- Digitigrades where they walk and run on digits. Examples - cat, dog.
- Unguligrade where the walking and running is done on tips of digits and the ends of the digits are modified into a nail called hoof. Example, rhinoceros, cattle, horse.
