Answer 1

• This is a biology question

Answer:

B) die back as other larger plants begin to grow

Explanation:

The graphs which show ecological  succession taking place after a disturbance, has the grasses and mosses represented by "2". The curve tagged 2 represents the growth path of grasses and mosses after the disturbance.

From the graphs, we can see that after the disturbance, the growth of mosses and grasses starts on bare rocks and increases steadily as the slope of the curve rises. The curve tagged "2" begins to slope downwards, indicating a steady decline in the growth of mosses and grasses as other larger plants begin to emerge.

Therefore, from the graphs, we can infer that mosses and grasses grow over bare rock, and then die back as other larger plants begin to grow. Some of the grasses and mosses still survive but their growth is reduced in the presence of other larger plants and fast growing trees as they are unable to compete for space, nutrient and sunlight with them.
