How are foods the similar to gaps observed in that remove or

How are foods the similar to gaps observed in that remove organic matter on surface of rocks forests? Both scour the landscape clean. Both uncover seeds in the soil. Both allow early species to colonize. Both happen only in climax seral stages. (Figure 19.14) If you excluded deer from the forest represented by the graph, what changes in importance would you likely see? Sugar maple\'s importance will increase both in the understory and in the company American beech\'s importance will increase in the understory. Tulip poplar\'s importance increase in the canopy. Tulip poplar\'s importance will be understory. In some areas of the western United States pines are an important part of the Climax community. Fires occur at regular intervals in these areas. How could fire maintain these pine populations? Fires allow pioneer species like annual grasses to colonize. Fires cause gaps in the canopy that allow early-succession species in thrive. Fires kill understory species, allowing pine seedlings to thrive. Fires make it easier for legumes to colonize, increasing will nitrogen.

Solution

Q.No

Answer

Explantion

C) Both allow early-succession species to colonize.

When rocks breakdown, it will release organic matter and the gaps which have been observed in forest will provide a suitable environment for the early succession species to colonize.

20

D) Tulip poplar\'s importance will increase in the understory

Obviously when you are going to exclude deer from the forest, the Tulip poplar’s importance will increase in understory

21

C)Fires kill understory species, allowing pine seedlings to thrive

Pines are seen needing the natural fire to regenerate and maintain healthy populations and that too the fire by killing all the understory species will provide suitable environment for the seedlings to survive
