Intro to EcologySlide2
What is ecology?
Ecology is the study of how organisms interact with one another and with the environment. Slide3
What is an ecosystem?
An ecosystem is a community of organisms and their non-living environment. Slide4
Biotic: living things that are part of the ecosystem, like plants and animals
Abiotic
: non-living parts of the ecosystem like soil, water, and sunlightSlide5
Your turn!!
Turn to the person next to you and tell them one example of a
biotic
factor, and one example of an
abiotic factor.Slide6
What is a Limiting Factor?
Limiting Factors
are…
Biotic and abiotic factors of the environment that
limit the growth of a species.Slide7
What is a Limiting Factor?
Populations would continue to increase if they had all of the resources they require in unlimited amounts, but there are always
factors that limit
their increase.Limiting factors
control population growth.Slide8
The picture to the right shows an animal living in its environment.
TALK ABOUT IT!!
With the people at your table, discuss what factors in the environment may limit the population of the animal pictured.Slide9
What is Carrying Capacity?
Because of these
limiting factors, each ecosystem has a finite (limited) capacity for growth connected to its
carrying capacity.Slide10
What is Carrying Capacity?
Carrying capacity
is the number of individuals of a species that an ecosystem can support.Slide11
What are the levels of organization in an ecosystem?Slide12
Organism
: one single living thing
(individual)
Population
: a group of interbreeding organisms in the same area
Community
:
ALL
organisms living in one areaSlide13
YOU TRY IT!!!
In your notes, fill in the Ecosystem Pyramid for the Florida ecosystem that you live closest to.Slide14
Take out a sheet of paper.
Create an inverted pyramid that shows individual through ecosystem. The pyramid will be of the savanna in Africa. (Think Lion King)Slide15
Savannah Challenge
Write a paragraph explaining what
would happen if a wildfire limited the growth of grass in the savannah.
Now turn to your partner and read theirs. Give them two positive remarks and two helpful remarks about their paragraph.Circulate the papers and read the rest of the tables
Grade you own work out of 5ptsSlide16
Bell work 10-1EXPLAIN how predators would be considered a limiting factor.
Use each scenario below to explain what would happen if the predator population increased and what would happen if it decreased.
Use the savanna
Use Ravenwater
PondSlide17
