Generally cacti grow in arid, dry or desert conditions; on occasion the soil can also be saline (due to high evaporation rates).
Cactus (plural cacti) is a general term used to describe a group of plants with similar features or characteristics, as such the adaptations below may be applicable to only some and not all cacti.
In order to adapt to these climatic and soil conditions "cacti" have undergone a number of physical adaptations over millions of years in order to survive and thrive:
Their leaves are normally reduced to spines or thorns; this reduces the amount of water vapour lost through transpiration and offers protection to the plant from predators which may want to feed off of it.
The stem has become thick and fleshy, allowing the plant to store water when it is available. The stem is also green and is the primary location for photosynthesis.
Plants are normally narrow and upright, reducing their exposure to the midday sun, some may have grey green colouring or fine hairs to reflect sunlight.
The plant strictly regulates the opening of the stoma to reduce the amount of water vapour lost to the dry air, for this reason most transpiration and respiration takes place at night.
They normally have a shallow root system directly below the soil, which is able to trap and absorb even the smallest amount of water that may fall. Many species also have extremely deep feeder roots which will tap into underground water sources if they are available, these roots can extend up to 30 metres below the soil.
They have a very limited flowering period. The process of producing flowers takes a heavy toll on the resources of the plant. Some species produce singular flowers which may only last 24 hours, in which time they need to be pollinated. Other desert dwellers such as Agave will only produce flowers once in its lifetime and normally at a maturity of about 50 years old - the plant then dies!
Some plants are adapted to process salt allowing them to grow in salty soils, these plants are generally referred to as halophytes, although they have "cactus" characteristics.
An organism that is suited to its environment exhibits traits and characteristics that help it thrive in its surroundings. These traits could include adaptations like camouflage, protective coloration, mimicry, or specialized body structures that aid in survival, reproduction, or obtaining resources. Overall, an organism that is well-suited to its environment is able to effectively compete for resources, evade predators, and successfully reproduce, ensuring its continued survival.
The crawling cactus adapts to its environment by storing water in its stems, reducing water loss through its spines, and spreading out to access more sunlight. These adaptations help it survive and thrive in harsh conditions.
Darwin proposed that natural selection takes place as individuals best suited to their environment survive and reproduce, passing on their advantageous traits to offspring. This leads to the gradual progression of characteristics that are favorable for survival in a given environment.
To care for a cactus vine in a home environment, place it in a sunny spot, water sparingly, and use well-draining soil. Avoid overwatering and provide support for the vine to climb. Prune as needed and watch for pests.
The change that results in a species being well suited to its environment is known as adaptation. This process allows organisms to develop traits that help them survive and reproduce in their specific habitat. Adaptation is crucial for the long-term success of a species in its environment.
Cactus.
a clean environment is best suited for viviparous animals
The cactus is a plant that usually thrives in a dry environment.
no
A monkey is suited to its environment for the same reason as every other living oragnism; to survive.
A cactus adapts to its environment by losing its spines to reduce water loss and protect itself from animals.
Mountain goat are suited to their environment as they have thick skin and hair on their body surface that protects them from cold.
Well suited to their environment.

adaptation
no,there would be little change because the cactus wont be able to adapt to the environment.
