This community becomes more complex as new species arrive. In the pea plant, tall and dwarf are the two contrasting traits for stem height. A climax community will persist in a given location until a disturbance occurs. After these plants germinate and grow, they die and decompose, and their remains create pockets of soil in which other plants, as well as fungi, can become established. , nduction.
