Question 11
The model illustrates different trophic levels.
Which statement describes the flow of energy and matter through the terrestrial ecosystem?
a
Energy is lost to the environment when organisms die, which causes there to be a larger number of plants due to consuming dead organisms.
b
Energy is gained by producers from soil nutrients, which causes there to be more frogs than herbivore insects.
c
Energy is gained by organisms at higher levels as they consume other organisms, which causes hawks to be larger than frogs.
d
Energy is lost as heat as it moves up the pyramid from the bottom, which causes there to be fewer hawks than plants.
Question 12
What kind of organism takes out the most carbon from the atmosphere?
a
Plants
b
Bacteria
c
Animals
d
Humans
Question 13
True
False
Question 14
a
The arrows flow of energy show most of the energy goes to the highest level consumer.
b
The arrows represent the flow of energy in one direction from producers to consumers.
c
The arrows point in the opposite direction of the flow of carbohydrates, like glucose.
d
The arrows show the flow of energy and why there are many more raccoons than grass plants in the ecosystem.
Question 15
What are the two major life processes that involve carbon and oxygen?
a
photosynthesis and respiration
b
coal formation and photosynthesis
c
fuel combustion and open burning
d
death and decay
Question 16
Which of the following would be a reasonable organism to find in the THIRD ORDER CONSUMERS level (circle)?
a
baobab trees
b
lions
c
white tail deer
d
seagrass
Question 17
Black bears eat a wide variety of grasses, berries, fish, and small mammals to provide them with energy for growth and development. When a black bear eats a fish, what is the BEST pathway of the energy the bear receives?

a
The fish contains energy stored in its muscle and fat cells.
b
The fish contains energy from nutrients in stream sediments.
c
The fish contains energy from minerals in the stream's water.
d
The fish contains energy from photosynthetic plants.
Question 18
a
Energy moves through the organisms from the bottom to the top and increases at each level.
b
Energy moves through the organisms from the top to the bottom and increases at each level.
c
Energy moves through the organisms from the top to the bottom and decreases at each level.
d
Energy moves through the organisms from the bottom to the top and decreases at each level.
Question 19
According to the diagram above, an area of the ocean has producers. These producers are surface dwelling that make their own food through . How can 5000 only support half a tuna? Energy gets used up at each level and only is able to move to the next level as it is used to maintain life or given off as heat waste.

Directions: Look at the below model of photosynthesis and respiration.
Based on the information in the model, what can the student conclude about cellular respiration?
a
Water is both a reactant and a product.
