Question

select all that apply
choose all features that confined the green algal ancestors of plants to water.
□ more predators in land - based ecosystems
□ the inability to produce chlorophyll in a high oxygen environment
□ higher levels of uv light on land
□ less water availability in a terrestrial environment

need help? review these concept resources.

Explanation:

• Higher UV levels on land can damage organisms.
• Terrestrial environments have less water availability which is crucial for green - algal ancestors. Land - based ecosystems did not necessarily have more predators initially for green - algal ancestors, and they can produce chlorophyll in high - oxygen environments.

Answer:

• C. Higher levels of UV light on land
• D. Less water availability in a terrestrial environment
