coniferous treesdeciduous trees and shrubbery
tall, fast growing grass as well as scattered shrubs and treespredominately a few different species of tall grass
18.How does the presence of permafrost in the tundra biome influence biotic factors?
Permafrost produces nutrient-rich soil that allows for a variety of vegetation to grow.Permafrost protects plant life from the occasional shrub fires that occur during the dry season.
Permafrost allows plant life to grow even during the cold season.Permafrost prevents most vegetation with deep root systems from growing because majority of the ground is frozen.
