LEARNING TARGET: TO DIFFERENTIATE BETWEEN LEVELS OF ORGANIZATION IN AN ECOSYSTEM, AND
TO IDENTIFY NICHES OF ORGANISMS
.
Come in quietly
Take out a notebook and vocabulary HW
As I am checking HW ,write tonight’s HW into agenda: Staple triangle
notes in notebook, this will help you for tomorrow quiz! Study
tonight!

What is the difference between population and community?
DO-NOW
R- Populations and communities make up an ecosystem
A- Populations are one species in an ecosystem.
Communities are all the species or many species in an
ecosystem.
C- For instance lets take the ocean ecosystem. A group of
lobsters is a population. A group of eels, fish, and sea
anemones living in a coral reef is a community. For
the record populations and communities are similar
because they both group species but are different.
LEVELS OF ORGANIZATION
FROM SMALLEST UNIT TO LARGEST
Organism
Population Community Ecosystem
Most organisms live together in their ecosystems
interacting with other populations, communities, and
abiotic factors
B. Biosphere - part of
the earth that supports life.
C. ECOSYSTEMS – SPECIFIC AREAS
FACTORS.
1.
OF THE EARTH MADE OF BIOTIC AND ABIOTIC
3. AN ECOSYSTEM IS MADE OF THE INTERDEPENDENCE
AMONG THE COMMUNITY’S POPULATIONS AND LIVING
AND NON LIVING FACTORS OF THAT COMMUNITY.
4. Habitat – the place where
an organism lives in an
ecosystem.
In all populations members
compete with other members
for food, water, mates, and
other resources.
D. Community - a
collection of interacting
populations.
Example: Trout population influences
the eagle population because they use
them for food. Less trout means less
eagles and vice versa.
Niche - a particular function of a species in its community. It is the job of an
animal unique to them for example the rainforests have hundreds of birds that
share a habitat but not a niche
Examples: Bees making honey
Lions control the population by being predators
Bacteria breaking down waste to return nutrient to soil
III. Adaptation – a change over
time to fit a new or
special use or situation.
EACH ORGANISM IS ADAPTED
FOR A CERTAIN ENVIRONMENT
CRITICAL THINKING
If we are traveling to a grassland and have grass, grasshoppers, mice, and red tailed
hawks what level do a group of red tail hawks fall into?
The same grassland has grass, bugs, mice, and prairie dogs what is this level of
organization?
If the park has birch trees, maple trees, and oak trees do these trees all make up the
same population?
If we add the abiotic factors to the grassland we have created a?
