Question

scenario 5: in many grasslands, a thick buildup of dead plants and dry grasses has created serious challenges for the environment. this dense layer blocks sunlight from reaching new shoots, and traps nutrients. without the occasional natural fires that once cleared old vegetation, the landscape begins to change—woody plants and trees start to spread, shading out native grasses and wildflowers that need open sunlight. some native species even depend on fire to survive, as certain grasses need heat to release their seeds, and animals rely on the open spaces that fires create. as the balance shifts, the grassland loses its unique character and biodiversity. scientists and land managers are now exploring safe ways to reduce this buildup and restore the natural processes that keep grasslands healthy.

1. summarize the problem affecting this grassland in one sentence.
2. based on the lesson 4.3 notes, what sustainable farming practice might be for this grassland? explain your answer to receive credit.

Explanation:

The problem affecting the grassland is the thick buildup of dead plants and dry grasses. This buildup blocks sunlight, traps nutrients, and changes the landscape (e.g., allows woody plants and trees to spread). It also disrupts the natural processes (like fires) that are needed for the grassland's health (e.g., some native grasses, wildflowers, and animals rely on open spaces created by fires; grasses need heat from fires to release seeds).

Answer:

The problem affecting the grassland is the thick buildup of dead plants and dry grasses which disrupts natural processes (like fire - related ones) necessary for grassland health (including sunlight access, nutrient cycling, and the survival of native species that depend on open spaces and fire - induced conditions).
