Due to increase of surface area, the nutrients move efficiently inside the cell.
Explanation:
The cells need to have a high amount of surface area as compared to their total volume because with increase of surface area, the nutrients move efficiently inside the cell. A large surface area to volume ratio indicates that the cell can be efficient in moving nutrients and waste materials around using through the process of diffusion but when the volume increases instead of surface area, the efficiency of the cell decreases, and cells won't be able to do its job efficiently.
Seasons are not biotic bc they are not living, and we know from playing Minecraft that savannas are not covered in conifers but are covered in grass and a few trees
