Introduction to Biology
and the Study of Life
What is Biology?

Biology is the study of organisms.
Bio – life
ology – study of
Organism:
We call these different fields of
Biological study, Branches__ of
Biology.
– Zoology: study of animals
– Microbiology: study of microorganisms
– Botany: study of plants
– Ornithology: study of birds
– Ichthyology: study of fish
– Herpetology: study of reptiles and amphibians
– Virology: study of viruses
– Entomology: study of insects
– Mycology: study of fungi
Part 1: What is Ecology?
What is Ecology?

Ecology is the study of how organisms
interact with each other and how they
interact with their environment.


An organisms environment is all the nonliving and living things that make-up it’s
surroundings.
The Environment
 Abiotic
Factors:
– Non-living factors
 Biotic
Factors:
– Living factors
 A - not
 Biotic – living

Part 2: Ecological Levels
of Organization
Ecological Levels of Organization

Brainstorm: Why have ecologists
organized the study of ecology into levels?
Ecological Levels of Organization

Why have ecologists organized the study
of ecology into levels?

Organization allows for:
– A better understanding of the material.

Organization allows for:
– A better understanding of the material.
– Quick and easy access to information.

1. Organism: A living thing

1. Organism: A living thing
2. Species: A group of organisms that are so
similar to one another, they can
breed/reproduce and have fertile
offspring, offspring that can also
reproduce and have offspring.

Ecology Term Practice

The Appalachian Trail (AT) is the longest hiking trail in the
nation. It is approximately 2,178 miles long and on average
takes three months to hike. One end of the Appalachian Trail is
located in Northeastern Georgia just seven miles away from the
city of Atlanta, while the other end is located in Maine. While
hiking the AT, it is common for hikers to come across mountain
lions, bob cats, squirrels, cottontail deer, and even black bear.
The Eastern Gray Squirrel can be a source of food for mountain
lions and bob cats. The Gray Squirrel usually makes its home in
oak trees. It lives in the holes drilled by woodpeckers. It
spends most of its time finding and burying nuts, as its main
source of food is hickory nuts, acorns, and/or walnuts.
Depending on the time of year, hikers may experience heavy
rain or even snow. Many hikers will tell you the trail is a
formidable opponent, because of its steep rocky climbs and
slippery muddy terrain after a heavy rain.
