Oikos: House and Ology: to Study
Scientific discipline in which the
relationships among living
organisms and the interaction the
organisms have with their
environments are studied.
An Ecologist is someone who
studies ecology.
The study of how living
organisms interact with other
living organisms. (Biotic)
The study of how living
organisms adjust to the non-
living factors in their
environment. (Abiotic)
The interactions between
Biotic and Abiotic Factors
make up the environment.
The interactions between
Biotic and Abiotic Factors
take place in the Biosphere
“Organisms are adapted to surviving in
the abiotic factors that are present in their
natural environments. If an organism
moves to another location with a
different set of abiotic factors, the
organisms might die if it cannot adjust
quickly.”
In five sentences,
describe what you
would see if you
went SCUBA
diving. Explain if
they are Abiotic or
Biotic.
Ecology: Study of how living organisms interact
with their environment.
Ecologist: someone who studies ecology
Biosphere: the living portion of the Earth.
Biotic: Living factor of an environment
Abiotic: nonliving factor of an environment
Aquatic: A biotic/abiotic factor that is associated
with water. Ex: aquatic animals, aquatic plants,
aquatic environments
Biosphere: The portion of the
earth that sustains life.
Biotic Factors: Animals, Plants,
Bacteria, Fungi
Abiotic Factors: water, pH,
temperature, sunlight etc.
A biogeochemical cycle is a repetitive process that
recycles/reuses Abiotic factors in the environment.
The exchange of matter through the Biosphere
Bio- Life
Geo- Rocks
Chemical- Matter or Nutrient
Cycle: Process
Matter is anything that takes up space
and has mass.
Matter provides nutrients needed for
organisms to function
Matter can be Biotic or Abiotic
Example: Rocks, Plants
A Nutrient is a chemical substance
that an organism must obtain from
its environment
A nutrient can be eaten or absorbed
through the environment
Example: food.
There are many Abiotic factors that have a
significant effect on living organisms
Biogeochemical cycles are essential to the
ecosystem
Think: What might be some issues with a certain
environment if one of these factors were low in
availability? (Hint: Limiting Factor)
The lowest level of organization
(when talking about ecological
communities)
Where an Organism lives is a
Habitat.
The Role an organism plays in
it’s environment is a niche.
A Group of the same organism
Organisms of the same population often
compete for resources.
What resources do organisms of the same
population compete for?
What might be an advantage to staying in
a population? EX: School of Fish.
A group of interacting populations
Organisms may or may not compete
for resources within a biological
community.
Could this school be considered a
Biological Community?
A biological community and all of the
Abiotic factors affecting it.
The size of an ecosystem can vary.
EX: the Tropical Rain forest. The Human
Mouth.
When a Large group of Ecosystems
overlap, this creates a Biome
What is a Biome?
A large collection of ecosystems
with the same climate and have
similar types of ecosystems.
All biomes combine make up the
Biosphere.
1. Organism
2. Population
3. Biological Community
1. Lowest level of organization
2. Group of the same organism
3. A group of interacting populations
1. Ecosystem
2. Biome
3. Biosphere
1. A biological community and all the Abiotic
factors that affect it.
2. A large group of ecosystems
3. All biomes on earth combined
Competition occurs when more
than one organism uses the same
resource.
What are some things that
organisms may compete for?
FOOD.**
