Answer:
a. Gametophytes of bryophytes
d. Sporophytes of seedless vascular plants
Explanation:
Bryophytes are non-vascular plants. The plant body is haploid gametophyte which is its dominant phase and bears sex organs. The gametophyte may be leafy as in moss and may be with thalloid as in liverworts.
Pteridophytes are seedless, true vascular plants. The plant body is the diploid sporophyte. The sporophyte is differentiated into true leaves, stem and roots.
They ensured that balance in the ecosystem was maintained. They ensure that the genetic diversity and species is maintained. Sea otters applied natural selection pressures on the sea urchins population hence maintaining their level such that they will not overgraze on the kelps. Overgrazing would severely affect the sea urchin population and consequently severely affect the sea otters population too.
