Question

why do plants, especially slow-growing trees, have difficulty responding to climate change? they move quickly. they can migrate from areas they cannot survive in. they cannot adjust fast enough to changing climates. they reproduce quickly

Explanation:

To determine the correct answer, we analyze each option:

• "They move quickly": Plants (especially slow - growing trees) are sessile (stationary) and do not move quickly, so this is incorrect.
• "They can migrate from areas they cannot survive in": Migration implies moving from one place to another, and plants (especially slow - growing trees) cannot migrate in the way animals do. Their spread is mainly through seeds or vegetative propagation which is relatively slow, so this is incorrect.
• "They cannot adjust fast enough to changing climates": Slow - growing trees have long generation times and slow growth rates. Climate change is happening relatively rapidly, so they may not be able to adapt (through processes like evolution or physiological adjustment) quickly enough to the changing environmental conditions. This option is consistent with the problem statement.
• "They reproduce quickly": Slow - growing trees typically have relatively slow reproduction rates compared to many other plants, so this is incorrect.

Answer:

The option "They cannot adjust fast enough to changing climates." (the third option in the list of choices)
