Ecosystems are areas made up of both living and non-living things. What are the living elements of an ecosystem called?
Abiotic
Biotic
Primary Producers
Primary Consumers
One abiotic element of a marine ecosystem is:
fish
algae
bacteria
salinity
The vast majority (over 95%) of aquatic ecosystems are made up of this type of environment.
Freshwater
Brackish water
Marine (saltwater)
Bottled water
A biotic element of an aquatic ecosystem is:
plankton
pH (potential hydrogen)
topography
temperature
This freshwater ecosystem plays a vital role in filtering pollutants, serving as a breeding ground for organisms, and preventing flooding.
Freshwater Wetlands
Intertidal Zones
Open Ocean
Coral Reefs
This ecosystem is where freshwater and saltwater meet.
Ponds
Rivers
Esturaies
Deep Ocean Abyssal Plains
The three types of marine ecosystems we discussed in class were:
Lakes, ponds, and streams
Estuaries, rivers, and swamps
Intertidal, coastal ocean, and open ocean
Lions, tigers, and bears....oh my!

Nitrogen
Carbon
Sulfer
lead
Which of the following is an abiotic factor that affects marine ecosystems?
Pressure
Algae
Pedators
Food Web
Where is the largest store of carbon contained?

Which process would most likely increase the dissolved oxygen level in a freshwater lake?
algae bloom
lake turnover
photosynthesis
respiration
What does DO stand for?

Dissolved osmium
Dissolved ozone
True or false: dead zones can occur in both fresh and marine waters around the world.
True
False
As water temperature increases what happens to dissolved oxygen levels?
increase
decrease
stay the same
flucuate
The Photic Zone (Sunlight Zone) houses 90% of life in our oceans. Why?
Phytoplankton (base of the food chain) conducting phtosynthesis
Apex predators (top of the food chain) consuming large marine organisms
Most ocean life tends to float to the top layer of the ocean
This is a great place for fish to hide from predators
As saltwater evaporates in a tide pool what happens to the salinity level of that water?
decreases
stays the same
increases
These rocks are:
