1. If nitrogen is in such short supply in an ecosystem that an animal's growth is affected,
A the animal becomes an autotroph.
B the animal becomes a heterotroph.
C nitrogen is not required for growth.
D nitrogen is a limiting nutrient.

(TAKS 3, Bio TEKS 12E.6)

G 50 percent.
H 33 percent.
J 10 percent.

(TAKS 3, Bio TEKS 12A.1)
3. Energy flows through an ecosystem
A in a cycle between organisms and chemicals.
B in one direction from autotrophs to heterotrophs.
C in one direction from heterotrophs to autotrophs.
D only when it is interrupted by humans.

(TAKS 3, Bio TEKS 9D.1)
4. An ecological model that represents the amount of living organic matter at each trophic level is called a(an)

J ecological pyramid.

(TAKS 3, Bio TEKS 12A.2)
5. Nitrogen moves through the biosphere
A by cycling within and between ecosystems.
