Energy Flow in Environment : Ecological EnergeticsKamlesh Patel
What is Energy:
The ability or capacity to do work,
Radiant, Chemical, thermal, mechanical, nuclear, electrical.
What is Energy Flow:
The existence of flora and fauna in ecosystem depends upon the cycle of minerals and flow of energy. Energy is needed for all the biotic activities. The only source of this energy is the sun. The entrance, transformation and diffusion of energy in ecosystem are governed by laws of thermodynamics.
It is as per the syllabus of M.Sc. NRM including detailed study of population ecology
It describes the meaning of population with respect to ecology and includes population attributes, dynamics, dispersal, Population growth models, survivorship curves and limitations.
It also entails factors that influence and regulate population growth on the basis of density.

The International Commission on Zoological Nomenclature (ICZN) acts as adviser and arbiter for the zoological community by generating and disseminating information on the correct use of the scientific names of animals. The ICZN is responsible for producing the International Code of Zoological Nomenclature - a set of rules for the naming of animals and the resolution of nomenclatural problems.
presentation contain different type of interactions, competition-intra and inter-specific, mechanism of competition-Exploitation and Interference, Mathematical models of Competition i.e. Hutchinson Ratio, Exponential Growth, Logistic Model, Lotka-Volterra Competition Model, Tilman's Resource Model, Results of Competition i.e. Range restriction, Competitive Displacement, Competitive Exclusion , Competitive Displacement Hypothesis, Ecological Niche, Evolution of new species, Factors Affecting Competition, Case studies
Community ecology, study of the organization and functioning of communities, which are assemblages of interacting populations of the species living within a particular area or habitat.
There are two laws of thermodynamics. On the other hand in our universe sun is the source of energy. Green plants are the only producer. Plants make their own food by sunlight with the help of water and carbon dioxide. Other animals get energy by consuming green plants, plant products and other animals. Hence the energy is cycle. So the ecosystem proves the two laws of thermodynamics.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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.
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”.
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.
Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
3. Key Topics
• Primary and secondary productions
• Trophic levels and energy variation with increasing trophic levels
• Energy flow, food chains and food webs
4. FUNCTION OF AN ECOSYSTEM
• Productivity of Ecosystem
amount of organic matter accumulated/ unit time
• Primary productivity: rate at which radiant energy is stored by
photosynthetic and chemosynthetic producers
• Secondary productivity: rate of energy storage at consumer level
• Net productivity: rate of storage of organic matter not used by the
heterotrophs or consumers
5. • Secondary productivity: rate of energy storage at
consumer level
• Consumers utilize already produced food in their respiration
and also convert the food matter to different tissues. So,
secondary productivity is not divided into ‘gross’ and ‘net’
6.
7. Food Chains in Ecosystems
• The patterns of eating and being eaten forms a linear chain called food chain
which can always be traced back to the producers
• In an ecosystem energy transfers from one trophic level to other in succession
• A trophic level can be defined as the nth position of the organism in the food
chain or number of links by which it is separated from the producer
8. Food Chains in Ecosystems
• primary producers trap radiant energy and transfer that to chemical or potential
energy of organic compounds
• When a herbivore animal eats a plant, organic compounds are oxidized, the
energy liberated and some of the energy is converted into heat
• If this animal, in turn, is eaten by another one, along with transfer of energy
from a herbivore to carnivore a further decrease in useful energy
• Such transfer of energy from organism to organism sustains the ecosystem
9. • The number of steps in a food chain are always restricted
Why???
• At each trophic level in a food chain, a large portion of energy is used for its
own maintenance and ultimately lost as heat
• organisms in each trophic level pass on less and less energy than they receive
• This tends to limit the number of steps or trophic levels to four or five
• The longer the food chain, the less is the energy available to the final member
10. • In nature, basically two types of food chains
• Grazing food chain
• Detritus food chain
• Grazing food chain: Starts from the living green plants, to grazing herbivores
and on to the carnivores
• Ecosystems with such type of food chain are directly dependent on an influx of
solar radiation
11. • Detritus food chain: starts with organic wastes, exudates and dead matter
from the grazing food chain, termed detritus
• The energy contained in this detritus serves as the source of energy for
detritivores
• In grazing food chain energy storage is entirely within the tissues of living
organisms while energy storage for the detritus food chain may be largely
external to the organisms and in the detritus itself
12. Food web
• In nature simple food chains occur rarely
• The same organism may operate at more than
one trophic level
• An organism may be eaten by several
organisms
• An organism may feed upon several different
organisms
• In an ecosystem various food chains are
linked together and intersect each other to
form a complex network called food web
13. ECOLOGICAL/ ELTONIAN PYRAMIDS
• Graphical representation of trophic relationship is called “Ecological
pyramid”
• In many ecological pyramids, the producer form the base and the successive
trophic levels make up the apex
14. ECOLOGICAL PYRAMIDS
• Terrestrial ecosystems and shallow water ecosystems contain gradually
sloping pyramids because producers remain large and characterized by an
accumulation of organic matter
• In aquatic ecosystems the pyramid of biomass for is inverted
• primary production is concentrated in the microscopic algae.
• At any one point in time the standing crop is low
15. Types of Ecological Pyramids
• Pyramid of number. The number of individual organisms at different trophic
levels of food chain
• Pyramid of biomass. The biomass of the members of the food chain present
at any one time forms the pyramid of the biomass
• Pyramid of energy. The pyramid indicates the amount of energy flow at each
level

20. FUNCTION OF AN ECOSYSTEM
• Primary productivity
• Gross primary productivity: total rate of photosynthesis including
the organic matter used up in respiration during the period
• GPP depends on the chlorophyll content (chl/g dry weight/ unit area)
or amount of CO2 fixed/g chl/hour
• Net primary productivity. It is the rate of storage of organic matter
in plant tissues in excess of the respiratory utilization by plants during
the measurement period.
