Tide Pool Ecology
1.
2.
Objectives:
Describe the ecology of a tide pool.
Describe the abiotic and biotic factors affecting
organisms living in a tide pool.
Ecology Terms
1. detritus
•
organic matter such as animal wastes and bits of
decaying tissue
2. food chain
•
the steps of energy transfer from primary producers
through consumers
3. food web
•
all of the interconnecting feeding relationships (chains)
in a community
Tide Pools
• found in the intertidal
zone
– part of the shore between
the high and low tide
marks.
• form in depressions in
rock when the tide
recedes
• Usually on a flatter bench

What conditions might affect the
organisms in the tidepools?
Abiotic factors
1. Temperature
•
fluctuates greatly throughout the day and year
due to the sun's heat and changes in
weather/seasons
2. Salinity
•
•
increases when water evaporates
decreases when freshwater rain and runoff
enters pools
Biotic factors
1. competition for space
(shelter from sun/heat in
crevices/caves)
2. competition for food
3. ability to avoid predators
Tide Pool Food Web
• Have at it!
– Use 6 different organisms that you found in the
tidepools and draw a food web.
– Label:
• Producers
• Levels of consumers
• Organism (common name and Phylum)
