Terrestrial Ecosystem
A terrestrial ecosystem is an ecosystem found
only on a landform.
It is a community of organisms and their
environment that occurs on the land masses of
continents and islands.
EPISD Standards Based Curriculum 20132014
Marine Ecosystem
Marine ecosystems are among the largest of
Earth's aquatic ecosystems.
Marine waters cover two-thirds of the surface of
the Earth.
Such places are considered ecosystems because the
plant life supports the animal life and vice-versa.
They can be contrasted with freshwater
ecosystems, which have a lower salt content.
EPISD Standards Based Curriculum 20132014
Freshwater ecosystem
Freshwater ecosystems are a subset of Earth's
aquatic ecosystems.
They can be contrasted with marine ecosystems,
which have a higher salt content.
Freshwater habitats can be classified by
different factors, including temperature, light
penetration, and vegetation.

predator
Relationship
r
e
y
Predator- an organism that is hunting and feeds
on prey.
Prey- the organism that is being hunted and fed
upon.
EPISD Standards Based Curriculum 20132014
Relationship
consumer
producer
• Producer- a living organism that can make its
own food.
• Consumer- an organisms that gets its food
from eating other living things, in order to
have enough energy to survive and reproduce.
EPISD Standards Based Curriculum 20132014
Relationship
parasite
host
Parasite- an organism that benefits at the
expense of the other organism.
Host- an organism that harbors a parasite
providing nourishment and shelter.

8.11B
investigate how organisms and
populations in an ecosystem depend
on and may compete for biotic and
abiotic factors such as quantity of
light, water, range of temperatures,
or soil composition
EPISD Standards Based Curriculum 20132014
Organisms & Populations
Organism – a living thing. Examples: plants, fish,
bacteria, etc. (pg. 74 – ScienceSaurus)
Population – all of the organisms of the same
species that live in the same place at the same
time. Example: a penguin population in
Antarctica (pg. 130 – ScienceSaurus)
EPISD Standards Based Curriculum 20132014
Biotic & Abiotic Factors in an
Ecosystem
Biotic – all of the living factors in an ecosystem.
Example: A Pine forest ecosystem has pine trees,
deer, owls, raccoon, mice, bacteria, turtles and ferns
all living and interacting with each other as well as
the abiotic factors. (pg. 130 – ScienceSaurus)
Abiotic – all of the non-living factors in an
ecosytesm. Example: A Pine Forest ecosystem has
rocks, air, sunlight and water that help the biotic
factors survive. (pg. 130 – ScienceSaurus)
EPISD Standards Based Curriculum 20132014
Competition & Dependence
Competition – occurs when more than one
organism or population tries to make use of
the same limited resource. Example: a larger
wolf usually will take away food from a smaller wolf,
since their food source is limited (pg. 132 –
ScienceSaurus)
Dependence – occurs when organisms and
populations rely on limiting factors, such as
food, water, light and living space (pg. 131 –
ScienceSaurus)
EPISD Standards Based Curriculum 20132014
Community
Community – populations living in the same
area with other populations. Example: the
lizard population shares the same
[email protected]
with the mesquite, bacteria,
snakes, etc. (pg. 130 – ScienceSaurus)
