Compare and contrast the relative importance of the sporophyte vs gametophyte generation between nonvascular plants (bryophytes), seedless vascular plants and seed plants, and explain the ecological significance of a larger sporophyte generation

The diagram shows the layers of earth. convection currents in which region influence the movement of tectonic plates

Which could be a pathway of food through an ecosystem
