i. A biome is a geographic area characterized by specific kinds of plants and animals, with deserts being one type of biome.
ii. Deserts have hot climates with less than 25 cm of annual precipitation and daily temperature extremes.
iii. Many desert plants and animals have adapted to their environment through mechanisms like storing water and nocturnal behavior.
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.
desert ecosystem
Deserts and semi arid lands are extremely specialised and sensitive ecosystems that are easily destroyed by human activities. The plants and animals that inhabit these dry areas can live only in this ecosystem.
Desert ecosystem, is usually believed to be barren, but this fragile ecosystem supports numerous amazing living creatures, known for their adaptability.
Deserts alone covers about seventh of the land surface. We normally call deserts as “sand seas or oceans of sands”. Most of the major desert areas like as the Sahara, the Arabian, the Kalahari, and the Deserts of Australia all lie between 10 and 30 degrees north or south of the equator. Deserts are dry ecosystems comprising a substantial part of the globe

Grassland Ecosystem- As the name implies, grasslands are open spaces in which a variety of grasses grow, with only a few trees scattered near rivers and streams. The amount of annual rainfall influences the type of vegetation – not enough to support a forest but enough to prevent it from becoming a desert. Grasslands are found on every continent except Antarctica.
Grasslands are known in different regions of the world by different names – prairies, pampas, steppes, and savannah among others. They are divided into two types – Tropical and Temperate.

Compare and contrast the climates and communities of two terrestrial.pdfarihantcomp1008
Compare and contrast the climates and communities of two terrestrial biomes. Include the
following in your comparison: a basic description of how their locations on the planet affect their
temperature and rainfall an explanation of how their climate causes different amounts and types
of life to flourish two specific examples of community interactions that occur in each
community.
Solution
Taiga is the largest terrestrial biome, it is also known as boreal forest. It spreads throughout the
Europe, North America and Asia. The climatic conditions include long and cold winter, and the
summers are short with rains. The length of the day is longer during the summers and shorter
during the winter seasons.
The conifers are the common plant species that grow in Tagia. Other plant species such as oak
and willow are distributed in the wet regions. The animal population include, seed eating
squirrels, moles (small mammals), deer, elk and moose (browsing animals). Also the predator
species like grizzly bears, wolverines and wolves are also present.
Desert biome:
•The average rain fall is 10 in. (25 cm) or less. Temperature ranges are typically extreme, which
contribute to the desert formation. Temperatures during night are very cold. Desert soils are arid
with no organic content. The plant and animal species are relatively less due to the water
scarcity. Most of the surviving species are draught and salt tolerant.
•The leaves and stems of desert plants are adapted to tolerate drought conditions. Plants are
typically widely spaced than those in humid climates.
•Desert animals had several adaptations to combat the water scarcity. Some of the animals such
as camels can store water and survive for several days without water and food. Many desert
animals are nocturnal. The low temperature during the night helps to avoid quick dehydration.
For example, some of the desert snakes. Some animals such as tortoise and mice spend most of
the time underground. Desert birds crisscross the skies most of their time in search of food.
Desert animals are more vulnerable to changes in the habitat and invasive predator species due to
their special adaptations..

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. What is a
Biome?
A biome is a geographic area
characterized by specific kinds of plants
and animals. Deserts, tropical
rainforests, and tundra are all types of
biomes. In the desert biome many
organisms have learned to adapt to the
hot climate and lack of supplements.
3. Deserts are formed by mountains blocking
the path of precipitation
Deserts can be hot or cold but they are
always dry.
They receive less than 25 cm of precipitation
annually.
They cover 22 million km2 or 1/5 of the
earth’s surface.
4. Hot Desert
eg. Thar, in Rajasthan, India
Rub-ab-khali, Saudi Arab
Cold Desert
eg. Gobi desert, Mangolia
Ica desert, Peru
5. A Desert’s
Characteristics
Climate Seasons
Animals Adaptations
Plants Significance to
humans
6. Climate
The desert is the hottest biome on Earth. It also has its
extremes.
It can be over 50 degrees during the day and below 32 degrees
at night.
Less than 25 cm or rainfall every year.
The amount of rainfall varies, but when it rains…it POURS!!!!
After a storm, the desert may not see any rain for weeks or
months.
8. Endangered Animals
Black Rhino The major causes of
endangered animals
Grevy’s in the desert are
Zebra mainly poachers and
unexpected drought.
King Cheetah
9. Plant Life of Deserts
There are several plants that are able to survive in the desert.
Most plants survive by their long roots to reach underground water
sources.
A Variety of cactuses
Prickly Pear
Dragon Tree
Octillo Plant
Desert Spoon
Boojum
10. i. The seasons are generally warm
throughout the year and very hot in the
summer.
ii. The winters usually bring little rainfall.
iii. Temperatures exhibit daily extremes
because the atmosphere contains little
humidity to block the Sun’s rays.
11. Many of the animals in
the desert have
become nocturnal.
Both plants and animals
have learned to store
water.
Tolerate Hyperthermia
12. Poachers are a main cause of dying animals. Poachers
catch animals of all kinds to make money for usually just
one part, like the elephant tusk.
With the growing popularity of transportation, many roads
are being built in not only the desert, but all the other
biomes.
The main problem with these roads are the fact that they
destroy habitats and endanger animals. Road kill is also a
main factor in these dying animals.
These problems can be easily taken care of if other means
of transportation were encouraged.
13. It includes the flora and fauna.
Deserts typically have a plant cover that is sparse but
enormously diverse.
Almost all of the animals living in the desert have
adapted to be able to better survive in the desert.
14.
15. Some desert flora include shrubs
eg. Prickly Pearls, Desert Holly and the Brittlebush.
Most desert plants are drought- or salt-tolerant
eg. Xerophites
Other desert plants have long Taproots
eg. Turnip
16.
17. Includes animals that remain hidden during daylight
hours.
As to control body temperature or to limit moisture
needs.
These animals adapted to live in deserts are called
Xerocoles
eg. Jack Rabbit, Kangaroo Rat, Coyote, etc.
18. Global warming and human development are
threatening desert survival.
19. Droughts directly affect the growth of vegetation.
Global warming is raising Earth's temperature, increasing the
chances of severe drought
Wild Fires will burn away the slow-growing fauna.
Thereby drastically changing the landscape
20. The long-term ramifications are the problem:
deserts experience very little rainfall.
Trees and plants will not be able to live on the remaining water.
the salt levels in the soil make the soil unable to support life.
The simple act of gathering firewood is destroying this fragile ecosystem.
For example, in the Sahel countries of Africa, firewood is being used up
30 percent faster than it is being replaced.
21. Threatened species like the Bald eagle, the
Desert Pupfish, and the Desert Tortoise.
The Desert Tortoise was listed as a threatened
species, April 2, 1990.
The “US fish and Wildlife Service” has its
own a threatened conservation programs.
The WWF (World Wildlife Fund) has many
conservation projects.
22.
23. The Gobi Desert is cold almost all year round.
Deserts spread through desertification. This
happens when grasslands surrounding deserts
become dry.
Some deserts have gotten nicknames such as
Death Valley because of the lack of water.
24. Oases are parts of the desert where plants
grow and water is almost always available.
An oasis is formed by a pool of water
trapped between layers of rock and the
desert floor.
The water can allow people to settle and
even grow crops in the desert.
25. Some of the major deserts are:
• Sahara (Africa)
• Great Basin (North America)
• Atacama (South America)
• Mojave (North America)
• Great Victoria (Australia)
27. The ten largest deserts
Rank Desert Area (km²) Area (mi²)
1 Antarctic Desert (Antarctica) 13,829,430 5,339,573
2 Arctic Desert (Arctic) 13,726,937 1,003,600+
3 Sahara Desert (Africa) 9,100,000+ 3,320,000+
4 Arabian Desert (Middle East) 2,330,000 900,000
5 Gobi Desert (Asia) 1,300,000 500,000
6 Kalahari Desert (Africa) 900,000 360,000
7 Patagonian Desert (South America) 670,000 260,000
8 Great Victoria Desert (Australia) 647,000 250,000
9 Syrian Desert (Middle East) 520,000 200,000
10 Great Basin Desert (North America) 492,000 190,000
28. Preservation of Environmental habitat.
Conservation of Endangered Species.
Strict laws for Poachers.
Human Interruption should be controlled.
