|
|
Increased amounts of sunlight are able to reach the ground while the pioneer species are decomposing.
|
|
|
Increased soil temperatures from decomposing pioneer species help tree seeds germinate more quickly.
|
|
|
Increased amounts of decomposing pioneer species remove nutrients that tree seedlings need to grow and mature.
|
|
|
Increased amounts of soil from decomposing pioneer species allow plants with more extensive root systems to become established.

Detailed explanation-1: -During secondary succession, which of these best describes why decomposing pioneer plants give way to larger, more complex plant species, such as hardwood trees? Increased amounts of soil from decomposing pioneer species allow plants with more extensive root systems to become established.
Detailed explanation-2: -Secondary Succession This type of succession is faster because the soil is already in place. In this case, the pioneer species are plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil. This lets other plants move into the area.
Detailed explanation-3: -Which of the following best describes when secondary succession occurs? Explanation: Secondary succession can be described as the colonization of a habitat that once supported plant and animal life but was abandoned due to ecological disturbance.
Detailed explanation-4: -Pioneer communities help enrich the soil. As generations of the mosses or lichens die, their remains decompose and are added to the soil. The soil is then able to support a greater variety of plant life. Second-generation plants usually include grasses and small shrubs.
Detailed explanation-5: -Secondary succession is usually faster than primary succession because soil and nutrients are already present due to ‘normalization’ by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate.
