Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
Recognize that grasses are typically pioneer species in ecological succession. They are among the first plants to colonize an area because they can grow in poor soil conditions and help stabilize the soil.
Grasses modify the soil conditions by adding organic matter as they die and decompose, which improves soil fertility and structure, making it more suitable for other plants like bushes and shrubs.
Bushes and shrubs generally require better soil conditions than grasses, including more nutrients and a stable soil structure, which grasses help to establish.
Consider the role of sunlight and nutrient requirements. While bushes and shrubs may need more sunlight and nutrients, the initial modification of soil by grasses is crucial for their eventual growth.
