od trees and your knowledge of science to answer
a tree that grows throughout eastern and northern
lin makers have made violins using the wood from
ows a violin to produce beautiful sounds has good
ood with good resonance has certain characteristics,
sults from slow growth. this type of wood is called
aries with seasons as well as environmental conditions,
e. the amount a tree grows each year is determined by
on a cross section of the tree. the space between two
growth. figure 1 shows the typical growth pattern for
2 use table 1 and figure 2 to answer the question.
which claim about the transfer of energy in the tonewood ecosystem is
best supported by data?
a at higher elevations, more energy is available to transfer from the
trophic level occupied by the red deer than from the trophic level
occupied by the norway spruce.

b more energy is available to transfer from the trophic level
occupied by the red deer at lower elevations than from the same
trophic level at higher elevations.

c at lower elevations, more energy is available to transfer from the
trophic level occupied by the italian wolf than from the trophic
level occupied by the european spruce bark beetle.

d more energy is available to transfer from the trophic level
occupied by the norway spruce at higher elevations than from the
same trophic level at lower elevations.

Explanation:

To solve this, we analyze each option:

• Option A: Red deer (consumer) and Norway spruce (producer) are different trophic levels. Producers have more energy than consumers, so this is incorrect.
• Option B: Red deer are consumers. At lower elevations, there's more primary productivity (from producers), so more energy is available to red deer (same trophic level) at lower elevations than higher. This aligns with energy flow (more energy at lower elevations for consumers in same trophic level as more producers exist there).
• Option C: Italian wolf (higher consumer) and European spruce bark beetle (lower consumer) – higher trophic levels have less energy, so this is wrong.
• Option D: Norway spruce (producer) – producers have more energy at lower elevations (more growth conditions), so this is wrong.

Answer:

B. More energy is available to transfer from the trophic level occupied by the red deer at lower elevations than from the same trophic level at higher elevations.
