There is no better way you could have explained it. Thank you so much

Which of the following rows correctly describes the biotic and abiotic factors that change during each type of succession?
a.Type of Succession Abiotic Factors Biotic Factors
Secondary Soil is still present. Plant diversity will increase.
b.Type of Succession Abiotic Factors Biotic Factors
Primary Plant diversity will decrease. Lava from volcano will harden to produce new land.
c.Type of Succession Abiotic Factors Biotic Factors
Secondary Plant diversity will increase. Soil is still present.
d.Type of Succession Abiotic Factors Biotic Factors
Primary Lava from volcano will harden to produce new land. Plant diversity will decrease.
My answer:
Eliminate B immediately because plants are not abiotic, and soil and lava are not biotic but are the opposite; as well as C for the same reason. I'm not sure which of A and D is correct because plant population
decreases because of the disturbance in primary succession, and in secondary succession plant diversity
increases because of the "re-newed" environment...
Succession can be viewed as the effect of ____i____ competition on a community in which ____ii____ species tend to gradually be outcompeted by ____iii____ species.
The row below that best completes the statement above is row
a.intraspecific; K-selected; r-selected
b.interspecific; r-selected; K-selected
c.interspecific; K-selected; r-selected
d.intraspecific; r-selected; K-selected
My answer: option B. because humans and other factors (fires, retreating glaciers, volcanic eruption, etc) are often the cause of succession which means interspecific competition. Since humans are K-selected species they out compete the plants (both r and K selected)
something about my answer doesn't feel right though...
