Saproxylic species feed on the remains of these organisms. Specialist natural enemies of these organisms stabilize communities containing many species of them in the Janzen–Connell hypothesis. These organisms only reproduce after a disturbance in the most common example of fire-mediated serotiny. (20[3]0[1])The final seres (“sears”) and the climax community are dominated by these organisms at the (20[1])(*) highest (0[1])stratozone (10[1])at the end of ecological succession. (10[2])These organisms form communities (10[1])called stands. (10[3]0[1])The emergent layer emerges above (10[1])these (10[1])organisms, (10[2]0[2])which cannot live north of a line of (10[1])latitude (10[2]0[1])or above (10[1])a line (10[1])of elevation (10[4])that demarcates (10[1])the boundary (10[1])between (10[1])taiga and tundra. For 10 points, name (10[1])these terrestrial plants that form the canopy of a forest. (10[2])■END■ (10[5])
