estuaries
wetlands
deep oceans
costal oceans
Which adaptation would best help a lily pad survive in the moving water of a stream?
long roots
large leaves
sweet scent
white flowers
Reorder the following:
What are the four ocean zones of a marine ecosystem, from most shallow to deepest?
intertidal
neritic
bathyal
abyssal
Which of the following is the best definition of a wetland?
water that flows from a higher elevation to a lower elevation
large body of salt water
large body of fresh water
an area of land that is saturated by water at least part of the year
Wetlands are natural parts of watershed systems. In addition to having many natural processes, wetlands can also benefit humans. Which of the following is a way that wetlands can help humans?
increase flooding in adjacent towns and cities
decrease biodiversity where humans live
increase erosion near shorelines
protect nearby land from flooding
An estuary is part of a watershed system. Which of the following is the best definition of an estuary?
water that flows from a higher elevation to a lower elevation
large body of salt water
large body of fresh water
an area of land that is saturated by water at least part of the year
a mix of salt and fresh water where a river meets the ocean
Which answer choice describes a way in which estuaries benefit humans?
Estuaries contain coral reefs, where humans can go snorkeling and scuba diving.
Estuaries provide breeding grounds for many fish, which humans eat.
Estuaries contain large mammals, which humans eat.
Estuaries filter the fresh water that humans drink
Which of the following best states how living organisms fit into the water cycle?
The bodies of living organisms produced all the water on Earth.
The bodies of living organisms consist mostly of water.
Living organisms are a primary source of condensation.
Living organisms are a primary source of precipitation.
Which of the following statements about energy pyramids is true?
The smallest proportion of organisms are found in the top level.
The largest proportion of organisms are found in the top level.
Carnivores are most likely to be found in the bottom level.
Producers are most likely to be found in the top level.
What element can be changed by lightning into a form that plants can use?
Nitrogen
Phosphorous
Carbon
Oxygen
Drag the labels to the correct areas that demonstrate the words.
Below is an energy pyramid diagram. Why is the top so much smaller than the bottom?
Only the energy that is stored is available to the organisms at the next higher level.
Organisms gain energy as the food chain moves down the pyramid.
How is a wetland ecosystem different from other types of aquatic ecosystems?
The land that is covered is only covered by water all of time.
The land that is covered is only covered by water for a certain period of time, at least a month.
The land that is covered is only covered by water for a certain period of time, at least a year.
Choose 2 functions of wetlands.
protect shorelines from erosion
encourage erosion
filter dirty water
keep the ground wet
What enables organisms to use nitrogen?
nitrogen fixation
decaying plants
the atmosphere
Select each thing from the list that is a place where carbon can be found in the environment.
in fossil fuels
in living things
in bodies of water
in the atmosphere
Label the parts of the water cycle.
the movement of carbon through and between organisms and the physical environment
carbon cycle
the movement of water between the oceans, atmosphere, land, and living things
water cycle
the movement of nitrogen between the environment and living things
nitrogen cycle
states that mass cannot be created or destroyed by moves through the environment in different forms
law of conservation of matter
anything that has mass and takes up space
matter
states that energy cannot be created or destroyed, but changes forms
law of conservation of energy
the ability to do work and enables organisms to use matter in life processes
energy
a tool that can be used to trace the flow of energy through an ecosystem
energy pyramid
organisms that get energy by eating producers or other consumers
consumers
when bacteria in the soil are able to change nitrogen gas into forms that plants can use
nitrogen fixation
an important building block for organisms
carbon
organism that uses energy from their surroundings to make their own food
producers
(a) is the ability for organisms to produce their own (b) in dark depths of the ocean or caves.
