There is a giant sequoia (sequoiadendron giganteum) named washington (after george washington) that was believed to be the second largest tree in the world (at 253.7 ft. in height! ) until it was struck by lightning in 2003. the lightning strike caused a fire at the top of the tree that reduced washington's height to about 229 feet. the fire released carbon that had been sequestered in wood into the environment in the form of:

Carbon dioxide

Explanation:

Wood is composed of fibers and minerals. Fibers are nothing but the cellulose. Cellulose is polysaccharides that are made up of several units of glucose.  

Minerals with in the wood include carbon, hydrogen and oxygen. When wood burn it react with oxygen and carbon with in it combines with oxygen to release carbon dioxide. Sequoia too while burning released carbon in the form of carbon dioxide.  

we need additional information in order to determine the cause of death for anna garcia. there are at least 3 things with explanation included as to why we need them are as follows:

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
