Plants obtain nutrients through two main modes of nutrition - autotrophic and heterotrophic. Autotrophs, like plants, can synthesize their own food through the process of photosynthesis using carbon dioxide, water, chlorophyll and sunlight. Photosynthesis occurs in the leaves and produces carbohydrates and oxygen. Heterotrophs obtain nutrients by consuming other organisms and cannot produce their own food. Examples of heterotrophic nutrition include saprotrophic where fungi obtain nutrients from dead and decaying matter. Some plants also obtain nutrients through symbiotic relationships with algae or bacteria, or by trapping and digesting insects.
Plants are autotrophs that produce their own food through the process of photosynthesis using carbon dioxide, water, and sunlight. Photosynthesis produces carbohydrates from carbon dioxide and water and releases oxygen and water vapor as byproducts. Heterotrophs like animals and humans rely on autotrophs for food. Parasites feed on living hosts while saprotrophs feed on dead and decaying organic matter through extracellular digestion. Some organisms have symbiotic relationships where both partners benefit from living together, like lichen and rhizobium bacteria that lives in plant roots.
The document discusses the process of nutrition in organisms. There are two main types of nutrition - autotrophic and heterotrophic. Autotrophs like plants can synthesize their own food using photosynthesis, requiring carbon dioxide, water and sunlight. Heterotrophs obtain food from other sources and break it down using enzymes.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

4. INTRODUCTION
LET’S HAVE A LOOK ON THE
CONVERSATION OF TIKI AND TIKU !!!
Tiki : Hello ! Tiku
Tiku : Hi!! Tiki
Tiki : Where are u going?
Tiku : I am going to a Family function with my parents. Ohhh !!! I am so
excited about the party.. I will have so much of fun , delicious food……
Tiki : Ok ! That means you are excited about the food. Tell me one thing-
Why do we eat food ?
Tiku : Yes I know. We Eat food to get nutrients, energy , stay fit and healty.
Tiki : Do you know- What is this process of getting nutrients called?
Tiku : Yes I know….It is Called NUTRITION
Tiki : Yes you are correct. You Know Tomorrow our science teacher will also
start this chapter in our class. We will have lots of fun… See you tomorrow
in the class… Byeeeee…..
5. Nutrients
The components of food like carbohydrates, fats, proteins vitamins and minerals are called nutrients.
NUTRIENTS Help to
provide energy to carry out
life processes
repair the damaged parts of
their bodies
Grow and build their bodies
6. Nutrition
The mode of taking food by an organism and its utilization in the body is called nutrition.
NUTRITION
AUTOTROPHIC NUTRITION HETEROTROPHIC NUTRITION
Mode of nutrition in
which organisms prepare
their own food
Mode of nutrition in which
organisms cannot prepare its
food and depend upon others
8. Photosynthesis - Food making process in plants
Photosynthesis – Photo (light) + Synthesis (to combine)
Sunlight
Carbon dioxide + Water Carbohydrate + Oxygen
Chlorophyll
Raw materials for Photosynthesis
• Water and minerals
• Carbon dioxide
• Sunlight
• Chlorophyll
9. 1. Water and minerals :
2. Carbon dioxide
Water and minerals
Absorbed by the
root hairs of plants
Transported to the
various parts of
plants through
VESSELS
VESSELS are the long
tubes that runs through
out the plants and
transport water and
minerals
Carbon
Dioxide
Taken up by the
plant through
STOMATA STOMATA are the tiny
pores present on the
leaf surface surrounded
by GUARD CELLS
10. • 3. Sunlight :
Light That helps plants to Prepare their food
Energy
4. Chlorophyll :
Ohhhh !! That is why
the process is called
PHOTOsynthesis.
PHOTO means LIGHT
Wowww!!!
So Green you
are…
Who Are You?
I am the green color pigment
present in the leaves which gives
leaves its color and help it to trap
the sunlight so that it can prepare
the food
11. Then what about this?
It is not green in color.
How does it prepare its
food. No no!!! You are
mistaken….I have also
chlorophyll. But my
green color is masked
due to the presence of
some other pigment
like red and purple. But
I still can perform
photosynthesis
Photosynthesis is an unique process that supplies food directly or indirectly for all
living organisms and also passes the energy of the sun to all organisms through
plants. It also maintain the balance between Oxygen and Carbon dioxide in
atmosphere.
12. CLASSROOM ACTIVITY
AIM : To show that sunlight is necessary for photosynthesis
MARERIALS REQUIRED : A healthy potted plant, test tube, beaker, black paper strip,
watch glass, spirit(alcohol), iodine solution, bunsen burner, tripod stand
PROCEDURE : Take a potted plant and Keep it in a dark room for24 hours. Then take the
plant out from the dark room. Cover one leaf with the black paper strip and keep it again in
sunlight for another 24 hours. Pluck the stripped leaf from the plant and put it on a watch
glass then boil it in water followed by boiling in alcohol on bunsen burner. Then take out the
leaf from the test tube to a watch glass, remove the black strip and add few drop of iodine
solution to it.
OBSERVATION : The leaf turns blue black except the stripped potion.
CONCLUSION : This shows that sunlight is necessary for photosynthesis as the starch portion
of the leaf turns blue black due to photosynthesis performed in the unstripped portion of leaf.
13. Product of Photosynthesis
1. Carbon
2. Oxygen
3. Hydrogen
4. Nitrogen
Carbohydrate
(Glucose)
Initial product of
Photosynthesis
Starch
Indicates the
occurrence of
Photosynthesis
Now, Where does this
NITROGEN come
from
Nitrogen is present in air that
plant cannot use it directly.
Some bacteria (Rhizobium)
convert gaseous nitrogen into
its usable and soluble form in
the soil so that root can uptake
it from soil
14. Other modes of nutrition in plants
1. Parasitic nutrition
Cuscuta Plant (Amarbel)
So clever this
plant is !!
Cuscuta – A yellowish thread like structure without
leaves
Grow on other living plant - HOST
Hence called PARASITE
Derive its nutrition from other living organisms and
causes harm to them
That results in poor growth of the host plant
15. 2. Insectivorous Plant
Pitcher Plant
Insectivorous plant feed on insects
The leaf of the pitcher plant gets
modified to form a pitcher with a lid
Pitcher Lid
Lined with
downward pointing
hair and secrets
digestive juice
Able to open
and close the
mouth of
pitcher
When any insect enters into the pitcher,
gets trapped inside it and digested by the
digestive juices and the plant derive
nutrition from it
POOR
INSECT !!!
16. 3. Saprotrophic Nutrition
Rhizopus (Bread Mould)
Agaricus
(Mushroom)
Derives Nutrition from dead
and decayed matter
Performs Extracellular
Digestion
Absorbs the digested food
directly into the body
EXTRCELLULAR
DIGESTION ???
The type of digestion in which The
food is being digested outside the
body and absorbed by the
organisms.
17. Hey!!!
I am back with
my doubt bank…
Why do the
Pitcher Plant Feed
on Insect. As these plants grow on swap areas and lack nitrogen in
soil, so it feeds on insects to fulfill its nitrogen requirement.
REMEMBER : Nitrogen is very important for plant growth
Dodder plant
derive its nutrition
from other plants.
How does it do so?
Dodder plant sucks its nutrition from the host
plant as it has sucking roots.
I saw some yellow
patches on the leaf of
variegated plant. What
does that indicate?
The yellow patches on the leaves indicates the
absence of chlorophyll in that portion where
photosynthesis doe not occur
18. CLASSROOM ACTIVITY
AIM : To observe the fungus bread mould in bread.
MATERIALS REQUIRED : A slice of bread, water, magnifying glass
PROCEDURE : Take a piece of bread and moisten it with water. Leave it
in a warm place for 2 – 3 days till fluffy patches appear on them.
Observe the patches under a magnifying glass or microscope. Cotton
like threads are seen on the bread.
OBSERVATION : Some black –white patches with cotton like threads are
observed.
CONCLUSION : The white patches are Bread mould (Rhizopus). Bread
mould is a saprotroph. Saprotrophs get their food from dead and
decaying organic matterhttps://youtu.be/TUOUE3YLVuQ
19. 3. Symbiotic Relationship : A relationship in which two organisms live in a
close association and develop a relationship that is beneficial to both.
LICHEN
Simple !!! It has Chlorophyll
A close
association
between
An Alga
A Fungus
Prepares food by
photosynthesis
Absorbs water and
provide shelter
Yes I have seen
LICHEN – they
are found on the
bark of tree as
grey patches
But I have a
doubt…How this
Alga can prepare
food ?
20. LEGUMINOUS PLANT WITH
ROOT NODULES
A close
association
between
A Bacterium
(Rhizobium
Root of
Leguminous
Plant
Fixes Atmospheric
Nitrogen and make it
available in the soil in
its usable and soluble
form
Provides food and
Shelter to the
Bacterium
WoW!! This Bacteria
are so helpful…
Thank you Rhizobium
21. REPLENISHMENT OF SOIL
REPLENISHING
THE SOIL
WHAT
HOW
WHY
To enrich the
soil with
different types
of nutrients
Process of
giving the lost
nutrients from
the soil 1. Decomposition of dead parts of the
organisms
2. Bacteria like Rhizobium
3. Adding Manures and Fertilizers
22. WAYS OF
REPLENISHING
THE SOIL
Decomposition
of dead parts of
the organisms
Adding
Manures and
Fertilizers
Bacteria like
Rhizobium
Decomposition of dead plant
parts add give the nutrients back
to soil that is up taken by the
plants from the soil
Manures and
fertilizers contain
one or more of the
nutrients that plants
need to grow
Fixes the
atmospheric
nitrogen and make it
available for the
plants in the soil in
