Deserts are often referred to as dry land or arid land or a land with very little water. Alongside the tropical rainforest, savanna and swamp forests, the deserts are also considered as a part of the major biomes of the world.
Most people may have imagined all deserts to be very hot and dry. In reality, not all deserts are hot and dry. In fact, some deserts are actually cold and will remain cold throughout the year. An example of a cold desert is the Antarctica.
The desert environment is often characterized by very hot temperatures (at summer) and cold temperatures (at winter); with little or no annual (yearly) rainfall. In most cases, its annual rainfall is always lesser that 25 centimeters. In fact, the rate at which evaporation occurs in a desert exceeds its annual rainfall.
Note: An environment is defined as all external factors, internal factors, living factors and non-living factors that affect an organism. For instance, the soil, heat, air, water, plants and animals present in a desert constitutes the desert environment.
The living factors in an environment are often referred to as the biotic factors or biotic component while the non living factors are referred to as the abiotic factors or component.
Below is an image of a desert environment: (Notice a scarcity of biotic components on the desert ecosystem). This is a result of its extreme temperatures.
Certain plants live and survive in the desert. These are termed xerophytes. Xerophytes have got adaptive features that enables them to survive on soils that lack water.
Note: Some animal have adaptive features that enables them to survive in the desert. Examples include insects, snakes, camel and donkeys.
Deserts are found on each of earth's continent. They cover about one fifth of the earth's lithosphere and will often stretch from one country into another.
Below are examples of deserts, the countries where they are present and their respective continent:

Amazing facts in Biology
Women have more pain receptors than men
It's crucial you finish your antibiotics.
If you stop taking your antibiotics before you're supposed to, any bacteria that didn't get killed can develop an immunity to that antibiotic and become a super-strain, making it much difficult to kill in the future. So keep taking your antibiotics pill, even if you feel better.
Although rare, women can still give birth when they die. This is known as coffin birth
Men can actually get aroused post moterm. This is called priapism
There are more bacteria on your body that the entire human beings on earth
🦟 Mosquitoes 🦟 have killed more people than all the wars in history put together
The human 🧠 brain 🧠 does not feel pain. For this reason, neurosurgeons can perform brain surgery while the patient is awake
🦘 Kangaroos 🦘 can't walk backwards
There is an unusual plant found only in Australia's Daintree Rainforest. It's called the idiot fruit
Although the hippopotamus has a large head with a bulky body on stumpy legs, it still runs faster than a man
NOTABLE POINTS IN Biology
For a thing to be considered Living, it must possess all the Basic Characteristics of Life. These include:
Irritability or Sensitivity
During strenuous exercises like sprinting or 🏃 running, your body may actually work in the shortage of oxygen. During this time, your body owes oxygen (called oxygen debt) and it must be replenished or repayed after the exercise is stopped. This is why you breathe excess of oxygen after you stopped the exercise.
This is the concept of anaerobic respiration
A food Chain is a diagram that shows the relationship between plants and animals within a habitat on the basis of how they rely on each other for food.
Note: Habitat is a place where an organism live. It is of three types:
The term Biology originated from two Greek words. They are:
Biology can therefore be defined is the study of life
Anything that has life is generally considered as a living organism (or organism) 🌱🐐🐓. All living organisms must be able to carry the following activities:
The above listed points are often regarded as the basic characteristics of life. You can memorize them using the acronym (MR. NIGER DAC).
The gas used in the manufacture of food by plants is Carbon dioxide or Carbon(IV)oxide or CO2
Plants manufacture food through a process called photosynthesis.
Note: Plants are the only orgnisms that take away CO2 from the atmosphere
