solids having definite composition

Use and over-exploitation

Environment effects of extracting and using

mineral resources

Gems That Complete Our World.

Generally found in form of ores.

Is of great importance to mankind and used for

manufacture of useful products.

Earlier use of minerals in form of pigments.

Now days are used for manufacture of both

scientific and general purpose products.

Ranging from toothpaste to automobile batteries.

Also used as fluxes in metallurgy for separation of

different elements.

Metallic and non metallic minerals

Industries, construction, Housing

Consumer goods, Energy generation

Aircrafts (Aluminium), Communication system

Coins (Nickel)

Jewellery (Gold, silver)

Fertilizers, insecticides (Phosphorous, sulphur)

Mining is a process of extraction of valuable minerals from earth or from a ore body.

Materials recovered by mining include base metals , precious ones, diamonds even oil shale, rock salt and potash.

In a wider sense comprises extraction of any non-renewable resource(e.g petroleum, natural gas even water).

Effects of Mineral Depletion

Increasing cost of Fossil fuels, oil etc

More efforts to drill, results in

environmental abuse

Subsidence of land

Mining pollution, Health hazards

Groundwater contamination

Depletion of Soil Resources

Very much important to life, no one survive without

No substitute to water

Most critical limiting factor for many aspects of life:-

Economic Growth, Environmental Stability

Bio-diversity Conservation

Food Security, Health Care

1/4th World population have NO ACCESS to safe

drinking water.

Water Crisis

On average globally 70 % of water withdrawn

for agriculture

In India 93 % of water withdrawn for

agriculture

Kuwait uses only 4 % for crop lands

On average globally 25 % of water used for

industrial purpose.

Conflicts of water- Inter state and international

Sanitation

In India lack of adequate sanitation in rural

Out of 108 households, 14 households have NO

sanitation in urban area.

Of the 2.5 billion people in world that defecate

openly, 665 million live in India

88 % deaths from Diarrhea occur due to poor

hygiene, inadequate sanitation

Flush Toilets→ Not possible to provide→

Scarcity of Water

Ecological Toilets→ Practical, hygienic, cost-

effective

Ecosystem

Things to be learned…

Concept and Classification of Ecosystem

Structure and functions of Ecosystem

Producers, Consumers, Decomposers

Food chains, Food webs, Ecological pyramids

What is an Ecosystem?

Term proposed by British ecologist A. G. Tansley in

1935. Consisting of all Plants, Animals and Micro-

organisms

Region with Specific and Recognizable landscape form.

An ecosystem is formed by the interactions between all

living and non-living things.

Eco = The Environment

System = Regularly interacting and interdependent

components forming a unified whole.

Ecosystem = An Ecological system

An Ecosystem Mr. S. P. Deshmukh, Watumull Institute. 84

What is an Ecology?

The branch of biology that deals with the

relations of organisms to one another and to their

physical surroundings.

The study of the interaction of people with their

environment.

Fundamental Characteristics of Ecosystem

Structural

Living /Biotic

Non-living

/Abiotic

Inorganic components

Organic components

Climatic Regimes

Functional

Energy cycles

Food chains

Diversity

Nutrient cycles

Evolution

Structure:

Living/Biotic ( Plants, Animals and Micro-

organisms )

Non-living/ Abiotic (soil, climate, water and light )

Inorganic components - C,N,CO2

Organic components - Proteins, Fats

Climatic Regimes - Temp, Moisture

Macro and Micro consumers

On the basis of particular type of habitat, they are divided as:

Various Types of Ecosystems

Terrestrial Ecosystem

Forest

Grassland

Desert

• Running water

• Streams, Rivers

• Standing water

• Lakes, ponds

Marine

• Deep sea

• Oceans

Aquatic Ecosystem

Components of Ecosystem

Abiotic components:

1. Abiotic components are non - living chemical & physical factors in the environment.

2. They practically provides all the energy for ecosystems.

Biotic components:

1. Producers

2. Consumers

3. Decomposers

Examples of Producers

Grasses

Shrubs

Examples of Consumers

Herbivores

Carnivores

Omnivores

Decomposers Feed on organic compounds of dead or living plants

and animals for food and energy

Breakdown products & release inorganic compounds

(nutrients) in the ecosystem, making them available

again to producers.

“ The transfer of energy and nutrients through a

series of organisms with repeated process of

eating and being eaten”.

All the organisms are linked together with one

another by food relationship.

Each organism living or dead is potential food for

some other organism.

Food Chain

Food web Interlocking pattern of several interlinked food chains is

termed as FOOD WEB.

Ecological Pyramids

The relationship between producers, consumers and

decomposers at different tropic levels in an ecosystem.

Pyramid represents decrease in amount of energy,

number of organisms and biomass from producers to

higher level consumers.

Types of pyramid –

1. Pyramid of Energy

2. Pyramid of Numbers

3. Pyramid of Biomass

Grasses

Snakes, Frogs,

Birds etc.

Cows Sheep,

Deer, Rabbit

Lion, Tiger,

Elephant, Deer etc.

Carnivores

Herbivores

Producers

Phytoplankton's

Fish etc.

Zooplanktons

Carnivores

Herbivores

Producers

Grassland Ecosystem Forest Ecosystem

Pond Ecosystem

The occurrence of definite sequence of

communities over a period of time in same area.

A process through which ecosystems tends to

change, over a period of time

A change in the community in which new

populations of organisms gradually replace

existing ones.

Can be related to environmental changes.

Ecological Succession

Three stages-

1. Pioneer stage

2. Serial stage

3. Climax stage

E.g. Pond Ecosystem

Ecological Succession

Examples of Primary

Succession

Example of Secondary Succession

Basic Things To Remember About Ecosystems-

What is the nature / type of an ecosystem?

What are its structure and functions?

Who uses the ecosystems and for what purpose?

How is ecosystem degraded?

What can be done to protect it from deteriorating

in the long time? How can the ecosystem be

conserved?
