It IS NOT A because after a fire, soil remains, so it would be secondary, not primary. D is INCORRECT because after a volcano, only rock is left so it is primary succession, not secondary.
If you can post the picture I could tell you the correct answer.
It has a high energy phosphate bonds, due to the large amount of electrorepulsive force between the highly negative force between the highly negatively charged phosphate groups. Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP). When this happens, the ATP is said to be spent.
The processes used to encode, store, and retrieve information over time is known as memory.
<h3>
What is Memory?</h3>
This refers to the faculty of the mind and is also referred to as the psychological processes which goes in the brain which is referred to as the main structure of the central nervous system.
The memory is used to retrieve information about past experiences by individuals and aids learning process which s a very important aspect of the body system and also in machines. In a computer the memory is divided into two which are called the random access memory and the read only memory.
It is also used to encode, store, and retrieve information over time in diverse types of ways.
This therefore the reason why memory was chosen as the most appropriate choice.

Answer:
The bird's respiratory system consists of paired lungs, which contain static structures with surfaces for gas exchange, and connected air sacs, which expand and contract causing air to move through the static lungs.
Birds do not have a diaphragm; instead, air is moved in and out of the respiratory system through pressure changes in the air sacs. ... Bird lungs do not expand or contract like the lungs of mammals. In mammalian lungs, the exchange of oxygen and carbon dioxide occurs in microscopic sacs in the lungs, called 'alveoli.'
Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates. They serve to increase respiratory efficiency by providing a large surface area for gas exchange.
How do birds respire?
Some birds can sing while they fly! ... When the bird takes a second breath, the air in the lungs is sucked into the cranial air sacs -caudal thoracic, cervical, and clavicular. The cranial air sacs act as a holding chamber which provides a small back flow of air into the lungs during expirations.
