The document summarizes the key characteristics and adaptations of desert ecosystems. Deserts are defined as regions receiving less than 10 inches of annual precipitation and have extreme temperature fluctuations. Desert ecosystems are specialized, with organisms adapting to the harsh conditions through mechanisms like reduced water loss, water storage, and nocturnal activities. Common desert plants like cacti are succulents that store water and have lost leaves, while animals live underground or have features to dissipate heat. Despite the harsh conditions, desert farming is possible through extensive irrigation projects that bring water from distant sources, making regions like California's Imperial Valley highly productive agriculturally.
The presentation is aimed for undergraduate students and covers the details of forest ecosystem, grassland ecosystem, desert ecosystem as well as aquatic ecosystems. It is suitable for compulsory environmental science course at undergraduate level. The content has been simplified for easy understanding of both science as well as humanities students.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

2. What is a Desert?
• A desert is defined as a region which receives an
annual precipitation of less than 250mm [10
inches] on an average.
• Other than low precipitation,deserts are also
characterized by scarce vegetation and extreme
temperatures oscillating between 115F or more
during daytime and 32F or less at night.
• Deserts have dry climate due to rain-blocking
mountain ranges and remoteness from oceanic
moisture.
3. What is Desert Ecosystem?
In an ecosystem,the biological community
interacts with the abiological physical
environment for its survival.
The desert is characterized by extreme,
specialized and very sensitive ecosystem.
5. Adaptations in plants
• Desert plants have highly modified features that helps
them to thrive at extreme climatic condition.
• They have short growing seasons and long dormancies.
• The well known desert plant, cactus is a succulent,
meaning it has thickened, fleshy parts to store water.
• Stem is the only part that stores water and water is
stored as a thick viscous liquid.
• Cacti stem is called phylloclade.
• Cacti have lost true leaves during their adaptation,
retaining only spines which are

highly modified leaves.
In the absence of true leaves, the stem performs
photosynthesis with the help of stomata.
Transpiration, the process in which CO2 enters and
water escapes does not take place during day at the
same time as photosynthesis but instead occurs at
night because during the cooler, more humid night
hours water loss is significantly reduced.
7. Adaptations in plants
Another significant modification of cacti is its
extensive root system.
The roots may grow upto 100 ft under the soil to
access water and quickly react to rainfall by
immediately absorbing water that reaches the
ground surface.
10. Adaptations in animals
• To avoid heat : The animals avoid being out in
the sun during daytime and live in burrows to
escape intense heat.
• To dissipate heat: Animals have developed long
body parts that provide greater surface area to
dissipate heat. Light colours are poor absorbers
of heat. Most desert animals are pale in colour
which prevents their bodies from absorbing more
heat from the sun.
11. Adaptations in animals
• To absorb water: Desert animals have extra
tubules in their kidneys that help them extract
most of the water from their urine and return it
to the bloodstream and usually the wastes are
secreted in the form of insoluble uric acid. They
also filter the moisture out of their exhaled
breath through specialized organs in their nasal
cavities.
• To preserve water: Water is stored in fatty tissue
whose oxidation releases energy as well as water.
16. YES
Desert farming has become a
possibility today and the best
example is the IMPERIAL VALLEY
17. The Imperial Valley
• The Imperial valley is located in the Sonoran
desert of Southwestern California.
• High temperature and low annual rainfall of 3
inches [76 mm]
• Thousand’s of acres of desert land have been
transformed into one of the most productive
farming regions in California with an annual
crop production worth $1 billion.
18. The Imperial Valley
• Water distribution includes 1400 miles [2300
km] of canals and 1100 miles [1800 km] of
water pipelines.
• Water is supplied from the Colorado river via
the All American Canal.
• Major crops grown in the Imperial Valley are
winter fruits, vegetables, cotton, grains and
Alfalfa.
