What is Environment?
 The term "environment" refers to the surroundings or conditions in which
an organism, person, or community exists. It encompasses both the
physical and biological elements that influence and shape life. The
environment includes natural elements such as air, water, soil, plants, and
animals, as well as human-made elements such as buildings, roads, and
infrastructure.
 The environment is a complex and interconnected system where various
factors interact with each other. It can be broadly categorized into two main
components:
1.Natural Environment: This includes everything in the natural world, such
as ecosystems, climate, geological features, and biodiversity.
2.Built Environment: This encompasses the human-made or constructed
surroundings, including cities, buildings, transportation systems, and other
infrastructure.

What happening in our home?
 The current situation of Earth involves several
environmental challenges that scientists have
identified through extensive research and
observation.
 Scientists have used various methods such as
satellite observations, climate models, ecological
studies, and historical data to understand the
Earth's condition.
 These environmental issues have various
interconnected effects on Earth, including
disruptions to ecosystems, loss of biodiversity,
altered weather patterns, and potential threats to
human well-being. The reasons behind these
challenges are primarily linked to human activities
that exploit natural resources without adequate
consideration for sustainability.

Climate Change
 Introduction: Climate change is a pressing
global issue with far-reaching consequences
for the planet, ecosystems, and human
societies. It is primarily driven by human
activities that release excessive amounts of
greenhouse gases into the atmosphere,
trapping heat and causing a warming trend.
Understanding the causes, effects, and
potential solutions is crucial for addressing
this complex and interconnected challenge.

Climate
Change
 Causes:
1. Fossil Fuel Combustion: The
burning of coal, oil, and natural
gas for energy is the largest
contributor to greenhouse gas
emissions. Carbon dioxide
(CO2) released during
combustion significantly
amplifies the natural
greenhouse effect.
2. Deforestation: Clearing large
expanses of forests reduces
the Earth's ability to absorb
CO2, as trees play a vital role
in carbon sequestration. This
contributes to an imbalance in
the carbon cycle.
3. Industrial Processes: Certain
industrial activities release
potent greenhouse gases such
as methane (CH4) and nitrous
oxide (N2O), adding to the
warming effect. Agriculture,
livestock digestion, and waste
management are notable
sources of methane.

levels, posing a threat to low-lying coastal
areas and island nations. Changes in sea
levels also impact marine ecosystems.
 Extreme Weather Events: Climate change
intensifies weather patterns, resulting in more
frequent and severe events such as hurricanes,
droughts, floods, and wildfires. Communities
worldwide face increased vulnerability to these
extremes.
 Ocean Acidification: The absorption of excess
CO2 by the oceans leads to acidification,
harming marine life, particularly coral reefs and
shell-forming organisms. This has cascading
effects on the entire marine ecosystem.
 Disruption of Ecosystems: Changes in
temperature and precipitation patterns can
disrupt ecosystems, affecting migration
patterns, breeding cycles, and food availability.
Biodiversity loss becomes a significant
concern.

 Introduction: An ecosystem is a dynamic and interconnected
community of living organisms and their physical environment,
functioning as a complex, self-sustaining unit. These systems
play a crucial role in maintaining the balance of life on Earth by
facilitating the exchange of energy, nutrients, and matter.
Ecosystems come in various forms, with terrestrial and aquatic
ecosystems being two major categories, each exhibiting unique
characteristics and supporting diverse life forms.

Terrestrial and Aquatic
Ecosystem
 Terrestrial ecosystems encompass
environments that exist on land, ranging
from deserts and grasslands to forests and
tundras. These ecosystems showcase an
array of plant and animal life adapted to
specific climatic and topographic
conditions.
 Aquatic ecosystems encompass
environments that exist in water bodies,
including oceans, rivers, lakes, and
wetlands. These ecosystems support a
diverse range of aquatic life and are vital
for the overall health of the planet.

Food Web
 A food web is a complex and interconnected system that
illustrates the transfer of energy and nutrients within an
ecosystem through a series of interconnected food chains. It
provides a visual representation of the relationships between
different species within a community, showcasing how energy
flows from one organism to another.

Food Web
 Producers: The food web typically begins with producers, such as plants or
algae, which use sunlight to perform photosynthesis. These organisms convert
solar energy into chemical energy in the form of carbohydrates.
 Primary Consumers (Herbivores): Herbivores are the next level in the food
web, feeding directly on producers. They are the primary consumers that obtain
energy by consuming plant matter.
 Secondary Consumers (Carnivores and Omnivores): Secondary consumers
are organisms that feed on herbivores. They can be carnivores (eating other
animals) or omnivores (eating both plants and animals).
 Tertiary Consumers: Tertiary consumers are predators that feed on secondary
consumers. They represent the next level in the food web hierarchy.
 Decomposers: Decomposers, such as bacteria and fungi, play a crucial role in
the food web by breaking down the remains of dead plants and animals. They
recycle nutrients back into the ecosystem, making them available for use by
producers once again.

Food Web
 Characteristics of Food Webs:
 Interconnectedness: Organisms in a food web are interconnected in a
complex network of feeding relationships. This interconnectedness reflects
the interdependence of species within an ecosystem.
 Energy Flow: Energy flows through the food web in a unidirectional
manner, starting with producers and moving through the various trophic
levels. Each transfer of energy involves a loss, with only a portion passed
on to the next trophic level.
 Biotic Relationships: The food web illustrates various biotic relationships,
including predation, herbivory, and competition, that shape the dynamics of
the ecosystem.
 Stability: A diverse and well-balanced food web contributes to the stability
of an ecosystem. Changes in one population can have ripple effects
throughout the web, impacting other species.

Food Web
 Importance of Food Webs:
 Biodiversity: Food webs highlight the diversity of species within an
ecosystem and emphasize the intricate connections that support life.

ways, forming the intricate web of life within an ecosystem.
 Abiotic components encompass the non-living, physical factors
that shape and influence the ecosystem. These elements
provide the environmental conditions necessary for the survival
and functioning of biotic components.

Oxygen and Carbon Cycles
 The carbon and oxygen cycle involves the continuous movement of
carbon and oxygen between living organisms, the atmosphere, and
the Earth's crust. It consists of two interconnected processes:
 Photosynthesis: Plants, algae, and some bacteria absorb carbon
dioxide from the atmosphere during photosynthesis. In this process,
sunlight is used to convert carbon dioxide and water into glucose,
releasing oxygen as a byproduct.
 Cellular Respiration: Living organisms, including plants, animals,
and microorganisms, engage in cellular respiration, where they
break down glucose to obtain energy. This process releases carbon
dioxide back into the atmosphere and consumes oxygen.
 These processes maintain a delicate balance between oxygen and
carbon dioxide levels in the atmosphere, supporting life on Earth.

Phosphorus Cycle
 The phosphorus cycle involves the movement of phosphorus through the Earth's
lithosphere, hydrosphere, and biosphere. Key processes include:
