Question

which of these gymnosperms are known to be important in maintaining the balance of carbon in an ecosystem?
garden flowering plants
ferns and liverworts
mosses and horsetails
redwood tree forests

Explanation:

Gymnosperms are plants that have seeds not enclosed in an ovary. Redwood tree forests (which are gymnosperms) play a crucial role in carbon - balance. They absorb a large amount of carbon dioxide during photosynthesis and store carbon in their biomass. Garden flowering plants are angiosperms (not gymnosperms). Ferns, liverworts, mosses, and horsetails are non - seed plants (ferns are vascular, while liverworts and mosses are non - vascular).

Answer:

redwood tree forests
