This document provides an introduction to key concepts related to environment, ecology, and ecosystems. It defines environment as the external conditions that surround and influence living organisms. Environment includes biotic factors like other living things and abiotic factors like temperature, soil and minerals. Ecology is defined as the study of the relationships between living organisms and their physical environment. An ecosystem is the complex set of interactions between a community of organisms and their environment. The four main components that make up the environment are the atmosphere, hydrosphere, lithosphere, and biosphere, which all interact with each other in a closed, dynamic system.

Environment may be consider as our surroundings which includes everything around us, i.e. the non-living (abiotic) and living (biotic) environment.
The abiotic environment consists of air, water and soil, while the biotic environment includes all the living organisms (plants, animals, microorganisms) that we regularly come in contact.
Environment – Basic Concepts:
The environment is composed of four basic components:
i. Atmosphere
ii. Hydrosphere
iii. Lithosphere
iii. Biosphere.
The scope of studying environmental aspects is extremely wide and covers several crucial aspects of almost all disciplines.
The survival of any organism requires a steady supply of food and other materials and removal of waste products from its environment. The degradation of the environment is becoming a serious problem for the existence of human beings and other life. Pollution of soil, water and air causes harm to living organisms as well as loss to valuable natural resources. Several important aspects are studied under the field called as Environmental Studies.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
2. ◉ The word “Environment” is derived from the French word
“Environner” that means to encircle or surround.
◉ All the biological and non-biological things surrounding an
organism are thus included in environment.
◉ Environment can be defined as:
External surroundings and conditions which directly or
indirectly affects the living organism.
◉ It can also be defined as:
Environment is sum total of water, air, land,
interrelationship among themselves and also with human
beings, other living organisms and property.

4. ◉ Any constitutes of the environment which directly
or indirectly affects the growth and development of
an organisms is called environmental or ecological factor.
◉ E.g. climatic factor, biotic factor, edhapic (related to
soil) factors
ENVIRONMENTAL FACTORS
5. ◉ The word ecology is derived from two greek words
“oikos” meaning house, habitation or place of living and
“logos” meanings ‘study‘.
◉ Ecology is the study of interrelationship between living
organisms and their physical and biological environment.
◉ Physical environment includes light and heat or solar

as well as plants and animals.
ECOLOGY
6. ◉ Ecosystem is made up of two words “eco” and “system”.
Eco means environment and system means an interacting
and interdependent complex.
Definition of Ecosystem
1. The organisms of any community besides interacting
among themselves, always have functional relationship
with the environment. The structural and functional
system of communities and environment is called
ecological system.
2. It is a community of interdependent organisms together
with the environment.
3. Any unit that includes all of the organisms in a given area
interacting with the physical environment, so that a flow
of energy leads to clearly defined trophic structure, biotic
diversity and material cycles within the system.
ECOSYSTEM

◉ To improve attitude towards environment.
◉ To provide motivation for environmental protection.
◉ To increase participation and to develop a sense of
responsibility and urgency regarding environmental
problems and to ensure appropriate actions to solve the
problems.
OBJECTIVE ENVIROMENTAL EDUCATION
13. ◉ It consider environment in totality
◉ Itis nota short learning process but it requires a holistic
approach as it is multidisciplinary in nature.
◉ Environmental hazards are controllable and every citizen
has a moral obligation and towards this.
◉ Education can be given to all section of societies
◉ Promote the value and necessity of cooperation at
personal, local and national level in the prevention of
environmental problems and solution for it.
◉ Help learner to discover the systems and causes of
environmental problems.

agencies and everybody should work together.
PRINCIPLES ENVIROMENTAL EDUCATION
14. Environment can be divided in to 4 parts
1. Atmosphere
2. Hydrosphere
3. Lithosphere
4. Biosphere
COMPONENTS OF ENVIROMENT
15. ◉ Atmosphere= mixture of (gases +vapor + subatomic
particles) that entirely covers the earth extending
outward several kilometers.
◉ Major gases:
◉ Others include CO2, Ne, He, CH4, H2, CO, O3
Gases % concentration
N2 78%
O2 21%
Ar 0.9-1 %
Others 00.1-0.1 %
ATMOSPHERE

Vertical air movement,
which is responsible for
rapid and complete
mixing
Stratosphere 11-55 (temp increase) Ozone layer
Mesosphere 55-80
-75
(temp decrease)
--
Thermosphere Upto 500 (temp increase)
The heating in this layer
due to absorption of the
solar energy. Within the
thermosphere there is a
layer of charged particles
known as ionosphere
Exosphere Upto 2000 >= 1200
Airless and empty,
probably H2 gas is
(temp increase) ionized in this state
18. ◉ Water environment.
◉ 70% of earth is covered water.
◉ Water: Sea Ocean, lake, River, glaciers.
◉ It is estimates 1360 million cubic km of water.
◉ Out of this 97 % Ocean and sea, 2% in glaciers and
icecaps, 1% fresh water
HYDROSPHERE
19. ◉ The outer soil crust of the earth is lithosphere
◉ The living organisms, plant, and vegetation are supported
by the lithosphere.
◉ It also contains resources like minerals, organic as well as
inorganic matter and to some extend of air and water.
◉ It plays an important role as it not only produces food for
human beings and animals, but also the decomposition of
organic wastes is carried out by a host of microorganisms
in the soil.
LITHOSPHERE
20. ◉ Thin outer crust.
◉ Includes living organism and their environment.
◉ It extends from the lowest sea bed level to about 24 km of
the atmosphere.
◉ Biosphere= Lithosphere +Hydrosphere+ atmosphere
◉ The life supporting resources are also available from
biosphere.
◉ The wasteproducts in gases, liquids and solids waste forms
are discharged into biosphere.
◉ Though the sustaining and assimilative capacity of the
biosphere is tremendous but it is not infinite.
◉ The system is in operation for millions of years but now it
is showing stress, primarily due to impact of human upon
environment.
BIOSPHERE
21. ◉ Pollutant: For normal and healthy living a conductive
environment is required by all the living beings. The
favorable unpolluted or clean environment has a specified
composition. When this consumption gets changed by
addition of harmful substances, the environment is called
polluted environment and the substance polluting it is
called pollutant
ENVIRONMENTAL POLLUTION
22. ◉ Environmental Pollution: Any undesirable changes in the
physical, chemical or biological characteristics of any
components of the environment(air, water, soil) which can
cause harmful effects on various forms of life or property.
The various types of pollutants are:
1. Air Pollution
2. Water Pollution
3. Noise Pollution
4. Land Pollution
5. Thermal Pollution
24. ◉ Circle indicate sphere and curved arrow indicates the flow
path of matter.
◉ There is closed, dynamic, inseparable, organic coupling or
interrelationship among environment components.
◉ If one components changes, other component respond.
◉ Every sphere has two way linkages to every other sphere
including itself.
◉ Some arrow show transfer within a given components from
one location indicating movement of the substance from
one physical location to another without leaving the
sphere.
◉ Since the matter cannot be destroyed or created, the major
objective is to find the location and chemical form of the
substance at any given time
25. ◉ Atmosphere – transport component to receptor – storage
capacity small – great capacity for spatially
redistributing matter.
◉ Hydrosphere- classified 2 sub component
It Convey to rivers system which collects the substances
within the watershed and delivers then to second
subcomponent to ocean
◉ Lithosphere: solid shell of inorganic materials on the
surface of the earth.
It composed soil particles + under laying rocks downs to
the depth of 50 km
◉ Biosphere: thin shell of organic matter +comprising all
living beings – It is sum total of Hydrosphere +
Lithosphere+ atmosphere

IMPACT OF URBANIZATION ON ENVIRONMENT
28. Environmental degradation: “The overall lowering of
environmental qualities due to damaged caused by both
natural events and human activities in the basic structure of
the environment at local, regional and global levels adversely
affecting all living organisms including man”.
Reason :
◉ Increase of population growth
◉ Rapid deforestation
◉ Industrialization
◉ Unplanned urbanization
◉ Nuclear explotion
◉ Releasing toxic gases from atmosphere
◉ Power plants
ENVIRONMENTAL DEGRADATION
29. Impact can be calculate by following equation
I = P* A* T
Where,
I= Impact
P= Population size
T= Degradation pollution caused per unit of resources used
A=Per capita consumption of resources
In developing countries Ps or P3 i.e. population, poverty and
pollution are key factor for rapid environmental urbanization
which cause high rate degradation
Effects:
◉ Destruction of environment stability and ecology balance
◉ Natural activity like forest fire. Deforestation, earthquake,
floods, volcanic eruption.
30. ◉ SD is the need of present with compromising the need of
future generation,
◉ In other words, ever generation should leave air, water and
soil as pure and unpolluted as possible. Although it is a
difficult thing, it can be achieved through proper
environmental management.
◉ To meet basic requirement with increase of population,
industrialization is must, but it results in pollution,
environmental degradation and causes ecology unbalance.
◉ As the same time industrialization create job oppurtunity,
rises the standard of living and solve unemployment
problem.
◉ So require balance between environment and development
simultaneously, to achive goal SD is only answer.
SUSTIANABLE DEVELOPMENT
31. ◉ SD can be done if following consept are taken care of:
◉ Control of pollution
◉ Reduction of excessive use of resources
◉ Resource conservation
◉ Use renewable energy sources
◉ Recycling and reuse of material for waste minimization
◉ Use cleaner fuel and technology
◉ Concentrating more on social and economic development
of the community
◉ Development of good mass transport facility to reduce
pollution
◉ By using effective management tool like Environmental
management system like ISO 14001, Environment Impact
assessment (EIA) etc
