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 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.

During secondary succession, the 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.

Secondary succession

a type of ecological succession in which organisms recolonize a habitat after a major disturbance such as a flood, wildfire, lava flow, or human activity.
Primary succession does not have usable soils, whereas secondary succession occurs after a disturbance that leaves soil intact.

decomposing pioneer species increases the soil amount that allows plants with more extensive root systems to become established.

Thus, During secondary succession, the 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.
