a low place left over from the glaciers
a place in Canada with alligators
A marsh is best defined as
a flooded area with different types of grass
a flooded forest

The Chesapeake Bay is the largest estuary in the United States. What is an estuary?
It is a high place that separates two watersheds
It is a large area of land that drains rain into a bay
It is a mixture of fresh and salt water
It is the place where rivers meet the ocean
What is brackish water? (more than one is correct - choose all that apply!)
partly fresh and partly salty water mixing between rivers and the ocean
it is the water that is in an estuary
it is always dirty water
it can be very clear water
Oysters are important to the ecology of the bay because they (more than one is correct - choose all that apply!)
filter and clean over 50 gallons of water per day
are an important food source for many animals and people
are eaten by the alligators in Canada
make the Chesapeake Bay dirty
Bay grasses are important to the ecology of the Chesapeake Bay because they (more than one is correct - choose all that apply!
Produce nitrogen for fish to breath
Make a great home for the alligators in Canada
Help filter and clean the water by trapping leaves, sticks, and other debris
Produce a lot of oxygen for fish when they do photosynthesis
Abiotic factors in the Chesapeake Bay are (more than one is correct - choose all that apply!)
Living or once living (dead)
Never living and never will be
Air, water, rocks, metal, dirt
Animals, plants, fungi, and bacteria
If you are monitoring water quality and checking the salinity, what are you measuring?
The pH of the water
The amount of dirt in the water
The amount of salt in the water
The amount of pollution in the water
What is dissolved oxygen? (more than one is correct - choose all that apply!)
For land animals, it is oxygen dissolved in nitrogen - what we call air
For animals that live in the water, it is oxygen dissolved in water - fish breath it
It is the O in H2O and fish breath it
It is not the O in H2O because fish gills cannot break a covalent bond
If water has a lot of sediment in it, what might be there?
lots of dirt, sand, and tiny rocks floating in the water
oil from cars floating on the surface
oxygen
happy fish
Turbidity is a measure of
the amount of salt in water
the amount of dirt in water
the amount of oxygen in water
the amount of nitrogen & phosphorus in water
Algae is (more than one is correct - choose all that apply!)
commonly called pond scum
microscopic phytoplankton
a tiny plant that multiplies rapidly if there is fertilizer in the water
a little animal with claws and teeth
Fertilizer used to be cow manure spread on farm fields so plants would grow better, but today it is a mixture of chemicals sprayed on fields. What 3 chemicals are most commonly in fertilizer?
Oxygen, hydrogen & nitrogen
Nitrogen, phosphorus, & potassium
Oxygen, potassium, and iron
Phosphorus, sulfur, and lithium
Eutrophication , or a dead zone unable to support life, is what happens when there is too much _____________ _______________ in a body of water.
nutrient pollution
industrial pollution
acid rain
plastic pollution
A keystone species is the one (or two) species that an ecosystem depends on; without them, the entire ecosystem will collapse and die. What are the 2 keystone species in the Chesapeake Bay? (choose two)
whales
striped bass
oysters
bay grasses
