A. It is transferred as thermal energy released from basic metabolic processes before it is transferred to the next feeding level.
B. The energy is locked into the bonds, which cannot be broken by the animal at the next feeding level.
C. The energy is transferred into an unusable form during the consumption process
D. The energy is returned to the sun once the individual ceases to live

6. Darwins finches provide an example of an evolutionary process that describes how populations of organisms can adapt and change when introduced to a new environment. As the finches migrated to other islands where food resources were different, over time, there were noticeable differences in beak structures between finches of the islands.

A. Convergent evolution
B. Adaptive radiation
C. Homology
D. Vestigial
7. One of the cellular processes is growth. However, if a cell becomes too large, it cannot maintain homeostasis (maintaining a stable internal environment) by moving nutrients and wastes through a cell efficiently. What process is a cell likely to undergo to ensure that homeostasis is maintained?
