Multiple Choice

How does acid rain indirectly affect the bone health of herbivores in an ecosystem?

• By directly dissolving their bones

• By reducing calcium in soil, which affects plant growth and thus the calcium available to herbivores

• By increasing the calcium content in water sources

• By making the air more acidic, which affects breathing

Multiple Choice

Which of the following statements best describes the function of osteoclasts?

• They build new bone tissue.

• They break down old or damaged bone.

• They form cartilage before birth.

• They lengthen bones during adolescence.

Open Ended

Summarize how bone formation (ossification) and remodeling occur, and explain the roles of osteoblasts, osteoclasts, and osteocytes in these processes.
