Question

which form of life on land appears in the fossil record before all the others?
○ insects
○ fish
○ reptiles
○ plants

Explanation:

To determine which land - based life form appears first in the fossil record, we analyze the evolutionary timeline. Fish are aquatic, so they are not land - based. Among land - related life forms, plants colonized land earlier than insects, reptiles, etc. Plants are essential as they provided the necessary environment (like oxygen, food sources, and soil stabilization) for other land - based organisms to evolve and survive. Insects and reptiles evolved later as they depend on the plant - based ecosystem.

Answer:

D. plants
