C
Bushes and shrubs need less sunlight than grasses, which is not available initially.

Verified step by step guidance1
Understand the concept of ecological succession, which is the process of change in the species structure of an ecological community over time.
Recognize that during the initial stages of succession, the environment is often harsh and lacks nutrients, making it suitable for pioneer species like grasses.
Grasses are typically the first to colonize an area because they require fewer nutrients and can tolerate harsh conditions better than bushes and shrubs.
Bushes and shrubs require more nutrients and stable conditions to grow, which are not present in the early stages of succession.
As succession progresses, the environment becomes more stable and nutrient-rich, allowing bushes and shrubs to establish and grow.
