The diagram is a simplified model of Earth systems and their interactions. The model is used to analyze the causes and effects of global changes to Earth systems, such as changes to Earth's climate.
Which statement best explains why the model is useful for analyzing global changes to Earth systems?
The causes and effects of global changes involve one Earth system only.
The causes of global changes involve two Earth systems, and the effects involve the remaining two Earth systems.
Earth systems interact with one another, and the causes and effects of global changes involve all of the systems.
The causes and effects of global changes act separately on each Earth system, and the systems do not interact with one another.
A student is building a model of the carbon cycle and includes decomposers. How should decomposers be included in the model?
There should be an arrow pointing from decomposers to other elements; decomposers break down the bodies of dead organisms, converting carbon to other elements in the process.
There should be an arrow pointing from decomposers to other elements; decomposers break down soil nutrients, converting other elements into carbon in the process.
There should be an arrow pointing from decomposers to the soil; decomposers break down soil nutrients, absorbing carbon dioxide in the process.
There should be an arrow pointing from decomposers to the atmosphere; decomposers break down the bodies of dead organisms, releasing carbon as a byproduct in the process.
there would be more grass

Deer
Grass
rain
secondary, tertiary and quaternary consumer
tertiary consumer only
What would happen if the rat population rapidly decreased?
the rabbit population would also decrease.
the owl and rattlesnake populations would decrease.
the owl population would increase.
the wildcat would not have any food to eat.
How much energy is transferred from one organism to another?
only 10%
all of it, 100%
only 50%
20%
Organisms that produce their own food mostly through photosynthesis (producers). Examples are plants and algae.
Ominvore
Detritivore
Heterotroph
Autotroph
Trapping (or rabbit hunting) has severely reduced the population of rabbits in an ecosystem as shown in the bar graph. What is the most likely effect this will have on other organisms?
The snake population will decrease while the grass population will increase
The hawk population will increase and the rabbit population will decrease
The grass population will decrease and the snake population will increase
The grass, rabbit, snake, and hawk populations will all decrease rapidly

combustion
cellular respiration
decomposition
photosynthesis
The main way nitrogen is removed from the atmosphere and changed into a form plants can use is
Nitrogen Fixation
Nitrification
Ammonification
Denitrification
Which of the following is an example of how biogeochemical cycles are important in sustaining life?
The atoms of water molecules are destroyed during a drought.
Oxygen atoms are converted into carbon during cellular respiration.
Nitrogen in wastes are converted into useable nutrients for other organisms.
New carbon atoms are created during the carbon cycle.
Where is the largest reservoir for the phosphorus cycle?
rocks and minerals
the ocean
the atmopshere
fossil fuels
Biotic factors are ___________.
non-living parts of an ecosystem
living parts of an ecosystem
things that once were alive, but now are dead
