The diagram below shows the different aspects of the water cycle, such as how water is observed by plants and how it is carried around by the atmosphere.
The diagram relates to a cactus biome.
Cactuses are still plants,
We have several characteristics that make cactus a plant:
1. Photosynthesis
Unlike other plants that photosynthesize with their leaves, cacti do so with their stems. At night, they take in carbon dioxide, which is then used during the day.
2. The stem succulent
A cactus is classified as a succulent. In other terms, a succulent is a plant that has thick juicy stems or leaves that store water. A cactus stores its water in stems, and some species are adapted to arid areas.
3. Special skin surface
One attribute that makes cacti not lose a lot of water is the fact that they have waxy surfaces that prevent evaporation. Some species also have ribbed surfaces that prevent splitting even when the plant expands during desert rainstorms.
4. Cactus spines
Cacti have spines that protect them from being eaten by animals. The spines also act as insulation during the dry seasons.
How do cactuses survive in the desert?
A cactus is able to survive in the desert due to the following features:
It has long roots that go deep inside the soil for absorbing water.
Its leaves are in the form of spines to prevent water loss through transpiration.
Its stem is covered with a thick waxy layer to retain water.
This shows how cactuses can survive without water and this relates to what the diagram shows however, the diagram shows that rain takes a part in the water cycle, whereas for cactuses, they don't need much water due to their extreme adaptivity.
But there are some similarities too, for example cactuses are still plants so they still photosynthesise and give us oxygen and whatnot.
Forgive me if this is wrong, I tried my best <3 Have a great day
(Forgive me if this is too long just use the important part)
