Question

which of the following was a challenge for plants and animals when adapting to life on land? a.) moving around without water for transportation b.) absorbing carbon dioxide from the atmosphere c.) receiving enough radiation to maintain temperature d.) experiencing too much ozone

Explanation:

In an aquatic environment, water can aid in movement. On land, plants and animals lack this medium for transportation - they need to develop structures and mechanisms to move. Absorbing carbon - dioxide is a normal process for plants and not a major adaptation challenge when moving to land. Receiving enough radiation for temperature maintenance is not a key challenge compared to movement. Ozone is mainly in the stratosphere and not a direct challenge for adaptation to land life in terms of quantity.

Answer:

a.) Moving around without water for transportation
