Ecology
ECOLOGY
- a term coined by a German
biologist Ernst Haeckel, 1866
- From the greek:
oikos = the place where one lives
logos = study of
Ecology then, is the study of how
organisms interact with each other
within their natural setting/
environment
ABIOTIC and BIOTIC
factors
Abiotic = non-living factors
e.g. sunlight, temperature, wind direction
and strength
Biotic = factors caused by the presence or
role of other living things
e.g. interaction of plants with insects in their
environment
Non-living parts of your
community (Abiotic)
Buildings
 Roads
 Bodies of water
 Land
 Wind
 Sunlight

Abiotic factors affect distribution of species
Abiotic factors of interest include:
- Temperature (range from 0 to 45 C)
- Water
- Sunlight
- Wind (increases heat & water loss)
-Rocks and soil
-Amount of oxygen in the water
Stewardship
Acting in a way that involves taking
personal responsibility for the
management and care of something
Issue
A problem or concern facing the
earth’s climate, environment,
resources, etc
Sustainability
•living organisms like plants, animals, bacteria,
insects and other living things that can interact
and reproduce indefinitely
•For ex: Long-lived and healthy wetlands and
forests are examples of sustainable biological
systems.

What are Endangered Species?
An endangered species is a POPULATION of organisms
which are AT RISK of becoming EXTINCT because it is
either few in numbers, or threatened by various factors.
Some of the factors are:
-Loss of species habitat due to accommodating for
growing human population
-Pesticide use
-Hunting and trading
-Pollution
EXAMPLES OF ENDANGERED SPECIES:
SEA OTTER
DHOLE
SIBERIAN
TIGER
