10.1 Life Processes
Activity 10.1
e.g.
Able to move - movement
Nutrition
respiration
excretion
Respond and React - Sensitivity
transportation
reproduction
sensitivity
growth
These are some of the processes that help the
living being to sustain. These process that are
common to all living beings are called as the
life processes.

Think over it
Is there a difference between an inanimate
object and a dead object ?

Energy for life processes
All living organisms require energy to perform
various activities. This energy is derived from
the food they eat.
Food contains several components called as
nutrients. Based on their functions nutrients
are divided into three types

• Energy giving
• nutrients

- Carbohydrates, fats
(2) Body buildings nutrients
- Proteins
(3) Protective and regulating
nutrients
- Vitamins and minerals
10
On the basis of chemical nature, the nutrients
are of two types
Inorganic Nutrients
Plants convert nutrients into organic compounds
through the process of photosynthesis.
Organic Nutrients
They include carbohydrates, proteins and fats
which are of animal and plant origin.
11
10.2 Nutrition

• The process of intake of nutrients and its
  utilization by an organism is nutrition.
• Nutrition provides the raw materials neede to
  sustain the life.
• The way by which an organism obtains its food is
  he mode of nutritions.

12
The following basic steps of nutrition remain the
same in all animal

• Ingestion

The act of taking food inside.

• Digestion

The process of breaking down of complex organic
food into simpler soluble substances. This is
done mechanically by teeth and chemically with
the help of enzymes.

• Absorption

After digestion is completed soluble
digested Food is absorbed into the blood.

• Assimilation

The absorbed food is transported into tissues
and cells of the body where they are used to
produce energy or for growth and development or
stored for future use.

• Egestion

The undigested and unabsorbed residues of food
are thrown out of the body.
13
10.2.1 Autotrophic Nutrition

• Autotrophic nutrition is the mode of nutrition in
  which organisms synthesize their own organic
  food.
• They use simple inorganic substances present in
  the surroundings for this process.
• Such organisms are called as autrophs.
• Most of the plants are autotrophs.

14
10.2.2 Heterotrophic Nutrition
Organisms that depend on other organisms for
their food are heterotrophic organisms. All
animals and fungi are heterophs.
e.g.
1. Fungi like yeast, mushroom.
2. Human being, cat, cow, etc.
3. Cuscuta, ticks, lice, leeches, tapeworms, etc.

A force is that physical causes which changes (or
tends to change) either the size and shape
of the body or the state of rest or the state of
motion of the body.

FORCES
Non-contact Forces
Contact Forces
The forces which act on bodies when they are in
physical contact are called the contact forces.
The forces Experienced by bodies even without
being physically touched are called Non-contact
forces or the forces at a distance.

Soils in India
Siddhi Hegde
30
Meaning of Soil
A thin layer of loose mixture of small rock
particles and rotting organic matter.
31
Formation of soils

• Parent rock material process of breakup or
  wear and tear.

• Various agents of nature
• Changing temperature
• Running water
• Wind

32
Soil Classification
According to formation
Residual
Depositional

• INSITU

• TRANSPORTED

• Example
• Black soil
• Red soil
• Laterite soil

• Example
• Alluvial Soil

Characteristics of fertile soil

• Moisture supply essential nutrients.
• Depth growth of roots.
• Nutrients nitrogen, phosphorus, potassium.
• Organic matter improves the structure.

Types of Soil
Alluvial Soil
Laterite Soil
Red Soil
Black Soil
36
Alluvial Soil
Soils formed by the sediments brought down by
rivers

• Riverine Soil
• found in the river basin
• Loamy Soil
• mixture of sand clay and
• silt

Charles Darwin -the theory of evolution of
life EARLY MAN According to Darwin, the early
man lived on the earth some two million years
ago. He lived in caves. HOMO ERECTUS This early
man evolved into a new Homo erectus before some
7.5 lacs years ago, who could stand in erect
pasture. HOMO SAPIEN Then there was evolution
of man into a thinking man (Homo Sapien).

PALAEOTHIC (OLD STONE AGE) The man of this age
used the tools made up of stones. Hand axe -
the first stone tool made by man. -used for
digging out roots and cutting chunks of meat.
MESOLITHIC (MIDDLE STONE AGE) The man of this
age preferred to live in community groups. The
institution of family -purpose of reproduction
and taking care of progeny.   Mesolithic people
developed the art of painting as can be seen in
the caves of Bhimbetka (Madhya Pradesh)   The
painting of rhinoceros hunt in the Adamgarh caves
indicate the assimilation of large number of
people for hunting of bigger animals. NEOLITHIC
AGE Man started cattle breeding in this age.
He began living in the huts made up of timber
and grass.

DOCKS
DOCKYARD
The remains of a large dock- discovered in
the excavation at Lothal - the length of 270
meters and the width of 37 meters.
45
SOCIAL AND CULTURAL LIFE

• Family- a primary unit
• Society - classified into administrators,
  traders and commons.
• Farming - backbone of social life.
• The Harappan men trimmed their beard, parted
  their hair at centre and women had various
  hairstyles.

46
COSTUMES

• It included the bronze mirror, ivory combs,
  hooks, hairpins, lipsticks, sticks to colour
  eyebrows etc.
• The necklace made of gold, bangles, waistband,
  and rings etc were discovered
• The dancing girls statue had the bangles in hand
  necklace.
