What is the role of plants in primary succession?

• They are not involved in primary succession

• They are the primary colonizers

• They follow animals in colonizing new areas

• They only grow after soil is formed

What does the term 'stochasticity' refer to?

• Predictable changes in ecosystems

• The final stage of succession

• The process of soil formation

• Randomness in ecological succession

What is the Intermediate Disturbance Hypothesis?

• Moderate disturbances are ideal for biodiversity

• Large disturbances are best for ecosystems

• No disturbances lead to high biodiversity
