The trajectory of succession proceeds toward:
Show answer Hide answer
Answer: A. Predictable
Explanation
Ecological succession generally proceeds along a directional and predictable trajectory toward a stable climax community. As pioneer species modify the local substrate, subsequent plant communities replace them in an orderly and recognizable sequence. This directional progression allows ecologists to forecast future vegetation changes based on current site conditions. Ecological succession is the process by which the structure of a biological community evolves over long periods. Primary succession begins on lifeless substrates like bare rock, while secondary succession occurs after a disturbance. Each transitional phase is known as a seral stage, culminating eventually in a self-perpetuating climax community.
Option B incorrectly labels the trajectory as unpredictable, ignoring decades of consistent ecological observation and research. Option C characterizes succession as haphazard, failing to recognize the orderly replacement of species over time. Option D states it is always changing without direction, contradicting the stable convergence toward a climax community.
