Quite simple, cactus live in areas where it rains only a few times a year, so it stores as much water as possible so it can survive in the desert
The roots to a cactus are long thick and go very wide and deep. When it rains the roots absorb the water and store it in its leaves. The cactus doesnt need a lot of water. A couple drops a year will keep it alive. Its leaves are protected with spines.
cactus's need minimal water and if you under or over water the can die. you should water a cactus once every 8 to 9 days if 60 degrees or more(inside or out), and should water it every 12 to 13 days in the fall or winter(inside), keep in mind that you should give the cactus 5-6 drops of food (fertilizer) each water. you can buy the cactus food (fertilizer) at you local plant store.Cacti should be watered whenever the soil has dried out, if you water them to much they will get root rot. When it comes to cacti its a good idea to water them sparingly than to much, they can thrive on small amounts of water but will die from to much water.
An oak tree can absorb about 48 pounds of CO2 in a year.
The cactus is one of the few plants found in the desert, and in order to survive it needs a massive amount of water. Since it does not rain all year round in a desert, cacti store water when it does rain. So the needles on the cactus protect their water-rich flesh from other things in the desert.
Summer due to amount of water evaporated by the cactus.
They only have to drink 69 times a year
The sagurao is a cactus, it doesn't eat anything. Does need some water, although only about 8 to 10 inches a year
'drinks' the little water the kalahari provides during the year (can be up to one meter high)
A barrel cactus can be seen any season of the year, particularly in the Sonoran and Chihuahuan Deserts.
If you know what a cactus you'll know it but if you don't know some plants really store food and water in their stems and did you know I am just a 10 year old
You could only survive if you were a cactus. A human could not survive one day in a hot desert on one cup of water per day.
