1. How do disturbances (or catastrophes) affect ecological succession? Be as specific as possible. Right answers only.
tino4ka555 [31]

Answer:

There are two types of ecological succession:

Primary succession:

Primary succession occurs in areas which were previously devoid of life. There were no organisms living in this area before. For example, lands after new glaciers or volcano  eruptions. Firstly, microorganisms begin to habitat this land, followed by plants like lichens, shrubs etc. Finally, complex life evolved from these.

Secondary succession:

Secondary succession arises in areas where life existed before but was destroyed due to natural circumstances like flood, fire etc. Small grasses inhabit this land first which are taken over by trees over  period of time.

An easy way to calculate the amount of energy available at each level is to
Contact [7]

Answer:

Use the rule that 10% of the energy is transferred between layers.

Explanation:

Energy is transferred between layers of a food pyramid. That means that the  producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).

However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers
