There are two plowed fields that are both the same size, have the same soil composition and climate. Both fields are surrounded by woodland. In the first field, as succession begins, the pioneer species are pine trees and shrubs. In the second field, the pioneer species are weeds and shrubs. This provides evidence for which model of succession?
A) the facilitation model
B) the tolerance model
C) the inhibition model
D) an opportunistic model
E) the climax model
Succession
The process by which ecosystems undergo change and development over time, often following disturbances.
Pioneer Species
The first species to colonize previously disrupted or damaged ecosystems, initiating a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.
Opportunistic Model
A concept or strategy where organisms or entities take immediate advantage of any situation or condition to achieve their goals, often with disregard for ethical considerations or long-term consequences.
- Comprehend the fundamental principles and frameworks of ecological succession, encompassing climax-pattern, facilitation, tolerance, and inhibition models.

Final Answer :
B
Explanation :
The fact that different pioneer species are able to establish themselves in each field suggests that both fields are equally suitable for colonization by different species. Therefore, the tolerance model is supported, where initial colonizers do not significantly alter the environment and each successive group of organisms is better adapted to the changing conditions.
