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.

Question:What adaptations helped the angiosperms to become the most successful and widespread land plant?
Answers:1. The vascular system allowed them to grow larger and shade their competitors.
2. Root systems kept them in place
3. Root system with a large surface area allowed for absorption of minerals, phosphates, sulphates, fixed nitrogen, and water. Especially water.
4. Root system allowed for mutualistic relationships with some fungi, and, in legumes, nitrogen-fixing bacteria
5. The waxy cuticle and bark slowed water loss even in direct sunlight
6. Pollen allowed plants to grow at a distance from each other in dry climates -- the sperm did not have to swim across the environment
7. Flowers (color, scent, nectar) attracted pollinators.
8. Fruits encouraged animals to spread seeds at a distance from the plant
9. Seeds containing nutrients and energy for the plant embryo within, allowing the seed to survive for years before germinating, thus allowing the plant species to "skip a bad year for germinating."
Question:Please can someone answer my questions
1. What is a habitat?
2. What is an adaptation?
3. Why are adaptations helpful for plants and animals?
4. Choose one plant and one animal and describe the habitat in which it lives.
5. Describe how the plant is adapted to live in its habitat.
6. Describe how the animal is adapted to live in its habitat.
i have alot of homework and would be very pleased if i could help with my work
Answers:There are many, you could try investigating different systems separately:
- skeleton: detachment of pectoral girdle from skull, attachment of pelvic girdle to column; vertebrae with zygapophyses, limbs with digits, etc.
- tegument: keratinization, impermeabilization, glands; thermal and hydric regulation.
- sensory: eye pigments, middle ear with tympanum, loss of lateral line system.
- other systems: lungs, kidney structure, large intestin, double circulation, etc.
Answers:Not drying out, crawling, and breathing air/not having gills.
Habitat and Adaptation :Check us out at www.tutorvista.com A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant or other type of organism. It is the natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population. The term "population" is preferred to "organism" because, while it is possible to describe the habitat of a single black bear, we may not find any particular or individual bear but the grouping of bears that constitute a breeding population and occupy a certain biogeographical area. Further, this habitat could be somewhat different from the habitat of another group or population of black bears living elsewhere. Thus it is neither the species nor the individual for which the term habitat is typically used. Adaptation is the evolutionary process whereby a population becomes better suited to its habitat. This process takes place over many generations, and is one of the basic phenomena of biology. The term adaptation may also refer to a feature which is especially important for an organism's survival. For example, the adaptation of horses' teeth to the grinding of grass, or their ability to run fast and escape predators. Such adaptations are produced in a variable population by the better suited forms reproducing more successfully, that is, by natural selection.
