# Ecosystem



Ecosystem is the interactions between Biotic and Abiotic

components.



Two types of components:-

1. Biotic components:- Consists of living organisms.

2. Abiotic components:- Consists of non-living part of ecosystem.



Ecosystem is the basic unit of Ecology.

# Environment



All physical,chemical and biological factors affecting the living

organisms are collectively called as Environment.



Environment consists of many ecosystems.

 A small pond is a small ecosystem while Earth is largest ecosystem.



Factors affecting the Environment:-

1. Natural factors:- Earthquakes,flood,tsunami,volacanoes,forest fire

2. Man-made factors:- Deforestation, hunting , poaching , pollution



Environmental balance is maintained through various natural cycles &

also with the food chains in an Ecosystem.

# Environmental Pollution



At present , many environmental problems have been arisen due to

effect of various natural and artificial factors.



Environmental pollution is one of those factors. Unneccesary and

unacceptable change in surrounding environment due to natural

events or human activities is called as Environmental pollution.



Population explosion, fast industrializtion , indiscriminant use of

natural resources, deforestation, unplanned urbanization these are

some factors responsible for Environmental pollution

 Various types of pollution like Air,Water,Sound,Soil,Thermal,Light and

also radioactive pollution causes Environmental pollution.



For living satisfactory life, human kept on snatching from nature and

this disturbed the Environmental Balance.

# Enviromental conservation and

Biodiversity



Biodiversity is the richness of living organisms in

nature due to presence of various

organisms,ecosystems & genetic variations in

species.



Biodiversity occurs in three different levels:-

1. Genetic Diversity:- Genetic Diversity refers to the

range of different inherited traits within a species.

2. Species Diversity:- Species Diversity is simply the

number and relative abundance of species found in

a given biological organisation

3. Ecosystem Diversity:- Ecosystem diversity

deals with the variations in ecosystems within a

geographical location and its overall impact on

human existence and the environment.

# Our role in Environment

conservation

Our role in

Environment

Control:-1)Preventing

harm

2. Stopping harmful

activity

3)Changing mindset

Production:-1)Revival of

harmed factors of

environment

2)Attempting

innovation.

Awareness:-

1)Eduction

2)Guidance, 3)

Imitation

4)Awareness,5)Partici

pation,6)

Organization Prevention:-1)Preventing

possible harms

2)Designing new plans

3)Harmful factors

Preservation:-1)

Preserving

whatever

leftover

2)Remedies to

prevent further

loss

3)Preserving

unknown

regions.

Conservation:-

Conserving the

available

sources.

# Endangered species



The species considered to be facing a very high risk of

extinction in the wild.



Number of these oraganisms is declined or their habitat is shrunk to

extent such that they can be ectinct in future if conservative

measures aren’t apply.



Ex.,

Giant Panda

Lion tailed Macaque Rhinoceros

# Rare species



A rare species is a group of organisms that are very uncommon,

scarce, or infrequently encountered.



Number of these organisms is considerably declined.

 Ex.,

Red Panda

Musk Deer

# Indeterminate species



The Indeterminate species are those species which are considered

under the category of threatened species.



Such species are defined under the IUCN red book data as the species

which are under the threat.



These organisms appear to be endangered due to their behaviour like

shyness
