Explain how an ecosystem that has experienced a disruptive event, such as a volcano, recovers.

       The main focus of the answer needs to be on nutrients and time.

Explanation:

       First of all, thinking about a volcano as a disruptive event in an island that is rich in biodiversity of plants and animals. After the event, everything will probably be dead, burned trees, animals and etc. Now nature needs time to recover, and it'll take a little bit of it to happen, but first of all, little plants will grow again with time, because remember, the plants that died will most of them be used by the soil to generate new ones, the first generation of plants will probably going to be little plants, these are the pioneer species, using the power of the soil to grow again.

        After that, we'll start having higher plants due to the work of worms, and too, birds that are going to start coming after the pioneer plants are stablished. The third succession is called climax, this is the part where the big trees start growing again, and they can survive by their own, using resources and carbon from the soil.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
