1) Water, they can live with out water for months.

2)Fruit bats feed on their pollen from the flowers to help photosynthesis.

3) Wind helps to disperce seeds. They are like dandylions.

Animals also eat their seed, and come out the other end.

Cactus will rot if they do not get a chance to dry out after being exposed to water.

They evolved in dry climates and have not developed any self protection against dangerous organisms that thrive in dampness.

Rose plants have prickles not thorns. Prickles are sharp pointed hairs that contain epidermal and subepidermal tissues. A thorn is a short, sharp modified stem. Roses use prickles to ward off predators which may help extend their life.

The adaptations of the cactus includes small and spiky leaves that reduce evaporation of water. It also prevents loss of water. The cactus has also a thick and juicy stem that stores water. It carries out photosynthesis like any other normal green plant.

Waxy leaves, long roots, have needles

Cactuses have many adaptions to survive in dry, hot regions. Such as:

- Being greyish/silver in color: To reflect heat of the sun and reduce water loss

- A swollen stem: To store water

- Rolled up leaves (only in certain cacti) to reduce surface area that is exposed to the sun, therefore preventing water loss

- Covered in thorns: Helps protect the plant from animals trying to eat it

They have needle-like leaves to prevent water loss by giving the sun a smaller area to evaporate water.

A moon cactus, or 'grafted cactus' is a cactus grafted on to another to grow as one. The top cactus is usually drained of it's chloryphll and cannot create it's own food, thus it uses the bottom cactus. The life spans of moon cacti are very short lived, but they're very pretty.

Moon cactus like sunlight, but not direct sunlight - for that will give them sun burn marks and can kill them. A few hours a day (4-6) of sunlight is good. Only water them when they're soil is COMPLETELY dry, and then water them well like a good thunderstorm. The next time you'll water them when they're completely dry again. The summer months (April - September) are when they're in there growing stages, so give them a cactus made fertilizer every month or two, not too much though, about half the strength it tells you to give on the instructions of the fertilizer. (I.E. Shultz Cactus Miracle-Gro) The summer months they need a little more sunlight and watering, but slowly start to slow down there watering as it gets closed to September because they need to go dormant in the winter in order to bloom next summer. In the winter, water them every month and sunlight is needed, and hard to find especially in winter (depending where you live) Also make sure they don't go below 60 degrees.

Good luck! If you need any more information I recommend the library for a book on cacti, or Google search 'moon cactus care'

Yes, a cactus is a producer. It makes energizing food from the photosynthetic interaction of sunlight with the plant's water, minerals, and dissolved nutrients. That food feeds the cactus, and cactus body parts may feed the consumers of the food chain.

The spines of the cactus are actually their leaves. They are so sharp and prickly to reduce the amount of surface area so they don't lose too much water in their native arid climates.

soak the finger or body part with the thorn in vinegar. It can be either white vinegar or cider vinegar, they both work the same. Or place cotton saturated with vinegar where the thorn is , and leave it in there for 20-30minutes. The thorn will just fall out.
