Which of the Following was a Challenge to the Survival

Question

Which of the following was a challenge to the survival of the first land plants?
A)too much sunlight
B)a shortage of carbon dioxide
C)desiccation
D)animal predation

Accepted Answer

The first land plants faced the challenge of desiccation, or drying out, which is a major threat to their survival on land. Without the support of water, plants had to evolve strategies to retain moisture in their tissues, such as developing cuticles and stomata. While the other options (too much sunlight, a shortage of carbon dioxide, and animal predation) may have been challenges to plant growth and survival, they were likely not the primary challenge that the first land plants faced.
