3.1 The Diversity of Organisms in Salt and Freshwater Systems
Name: ____________________8____ Formative Assessments
LEARNING OUTCOME #3: Analyze factors affecting productivity and species
distribution in marine and freshwater environments
3a-investigate life forms found in fresh water and salt water and identify and
interpret examples of adaptations to these environments
3b-analyze factors the contribute to the development of adaptations in species
found in saltwater and freshwater environments
3c-investigate and interpret examples of seasonal, short term and long-term
changes in populations of living things found in aquatic environments
1. Define “diversity”
2. Lake Diversity is freshwater bodies in low areas of land.

4. Adaptation is a __________________________ characteristic (like leg, wing, beak) or
___________________________ of a species (migrations, feeding habits, mating, fight
or flight). An adaptation increases the species’ chances of survival in a particular
environment.
5. List and explain the 5 different types of adaptations for aquatic life.
a) temperature:
b) light:
c) pressure:
d) salinity:
e) water movement:
6. A population is a __________________ of __________________ of the same species that
live in a particular area. ie: perch in Sullivan Lake is separate from perch in
Lesser Slave Lake.
7. Explain the 3 types of changes in populations and give a specific example.
a) seasonal changes:
b) short-term changes:
c) long-term changes:
8. What type of change would the following be?
Example
El Nino on fish
(pg 384)
Great Lake Zebra
Mussels
American Bullfrogs
in Vancouver
Landslide or
mudslide
Flood every June
Migration of

** Working with a partner, choose either the lake diversity or ocean diversity and
develop a model, poster, etc. to demonstrate the following:
a) the layers or zones of either a lake diversity or an ocean diversity
b) the type of organisms and plant life that live there
c) demonstrate two adaptations needed to live in this type of water habitat
(be specific)
d) explain population and how the population in a layer or level can change
