ECOLOGY
•Was coined by a germen biologist
Ernst Haeckel in 1866.
•Ecology is derived from the Greek
word Oikos which means “House”
and logy means “study”.
•Ecology is the scientific study of
interaction among organisms and
the interaction of the organisms with
the environment.
CONTINUE…
 The experts on ecology are called ecologist.
 The nature’s “house” come in many sizes,
from single cells to the entire planet. The
largest of these houses is known as
Biosphere.
LEVELS OF ORGANIZATION
 There are six levels:
1. Individual.
2. Population.
3. Community.
4. Ecosystem.
5. Biome.
6. Biosphere.
1. INDIVIDUALS:
 The individual is a specie that
they can breed and produce their offspring.
2. Population:
Population are the groups
of individuals that belongs to
the same species and live in
the same area.
3.COMMUNITIES:
 Assemblages of different populations that live
together in defined area.
4.Ecosystem:
 Is a collection of all organisms that lives in a
particular place together with their non-living
or physical environment.
5.BIOMES:
 Large systems called biomes.
 Biome is a groupe of ecosystems that have
the same clinical and similar dominant
communities.
6.Biosphere:
Contains the combine portion of the planet in
which all organisms exist, including land
water and air or atmosphere.
BRANCHES OF ECOLOGY:
 There are a lot of branches of ecology but
here we will discuss a few which are as
following:
 Plant ecology:
Is the study of plants, here ecologist study how
the plants grow and produce.
 Animal ecology:
Study of the animals and their communities.
CONTINUE…
 Human ecology:
In this branch of ecology we study about how
people relate to each other and as well as to
the environment.
 Applied ecology:
The use of ecological principals to solve the
real world problems.
CONTINUE…
 Medical ecology:
Study about the public’s health according to
their environmental aspects.
 Ecophysiology:
The study about the interaction of living
organisms with nonliving environment.
CONTINUE…
 Functional ecology:
The study about the species that play role in
the ecosystem.
 Fire ecology:
The study about the role of fire in the
environment of animal and plants and as well
as it’s effect on the ecological communities.
