The earth's history has had a significant effect on the characteristics of its organisms and biomes. how was the carboniferous period different from the devonian period? a. forests and land plants evolved during the carboniferous period. b. there were vertebrates in the carboniferous period, but not in the devonian period. c. there were an increased number of land-based organisms in the carboniferous period. d. there were vertebrates with four legs in the devonian period, but not in the carboniferous.

c. There were an increased number of land-based organisms in the Carboniferous period.

Explanation:

The big difference between the carboniferous and the devonian period is that there was an increase in the number of terrestrial organisms in the carboniferous period.

Occurred between 360 million and 290 million years ago, the Carboniferous Period contributed, as the term suggests, to the formation of coal, as well as enabling exploration in terrestrial environments by tetrapods from amniotic eggs. These tetrapods were the first birds, reptiles, and mammals, which at first had to feed through plants like seeded ferns.

In the Devonian period occurred the main transformations occurred in the flora, with the exponential growth of small terrestrial plants through the development of spores. With this process, the plants were able to fertilize with the seeds and reach the height of trees. They formed the earliest recorded forests with the emergence of lycopods, ferns and progimosperms.
