What is Ecology?
• Ecology –
– “eco” – Greek for “house”
– “ology” – “the study of”
• The scientific study of the
interactions and
relationships between
living organisms (plants,
animal, humans) and their
environments
ECOLOGY
Energy Transfer/Flow
Types of Organisms
Ecology of Organisms
Population
BIOSPHERE=
the thin volume of Earth and its
atmosphere that support life.
ECOSYSTEMS-
includes all of the
organisms and the non-living environmental
components found in a particular place.
COMMUNITIES-
includes all the interacting
organisms living in an area.
POPULATIONS-
includes all the members
of a species that live in one place at one time.
ORGANISMS-
simplest level= individual

• HAPPY FRIDAY!!!
• AGENDA: Review
Biogeochemical Cycles
• Activity: Review Mind

Biogeochemical Cycles
QUESTION: How does
our planet, as a whole,
work to recycle its
resources and provide
life?
ANSWER:
Biogeochemical Cycles
“Bio” – Life
“Geo” – Earth
“Chemical” – Chemical
Cycle – a periodically repeated sequence of
events
• Energy does NOT get recycled through an ecosystem, but chemicals
(nutrients) do!
• Water and minerals, such as carbon (C), nitrogen (N), calcium (Ca),
and phosphorus (P), are recycled and reused by plants, animals and
humans.
• Nutrients are recycled through living and dead animals (and humans),
the atmosphere, the oceans, and rocks.
The 4 Main
Biogeochemical Cycles
• Carbon Cycle - Photosynthesis and cellular
respiration.
• Water Cycle - Evaporation, Transpiration,
Condensation, Precipitation and Collection
• Nitrogen Cycle - death and waste; nitrogenfixing bacteria; reintroduced to soil for plants;
plants feed animals
Cycles Mind Map Review
Using what you know about Biogeochemical Cycles, please construct the following
Mind Map
Main Heading: Biogeochemical Cycles
1. Please include the definition and what each prefix means
Sub Heading #1: Water Cycle
1. Please include 10 facts
Sub Heading #2: Nitrogen Cycle
1. Please include 10 facts
Sub Heading 3#: Carbon Cycle
1. Please include 10 facts
In two paragraphs, discuss how the 3 Biogeochemical Cycles and Ecology relate to
each other and answer the following questions: How does the recycling of nutrients
and chemicals support life in ecosystems? What are three possible reasons
organisms would not survive without nutrients from the biogeochemical cycles?
What source of energy supports the functioning of the cycles and how does it relate
