Answer:
The correct answer is -
1. D. mold
2. A. Cast
3. F. trace fossil
4. C. original material fossils
5. B. fossil record.
Explanation:
Mold is the impression of an organism in a rock that occurs due to the complete dissolving of the organism and only an impression left in sedimentary rocks.
The cast is a fossil copy of an organism in a rock that takes place when water-containing minerals fill the molds and creates a three-dimension copy of the fossil.
Trace fossils are the fossils that are preserved in such a manner that records of biological activity stored only instead of remains of plants or animals.
Storing originals animals or parts of the remaining such as tissue of an organism in natural form is known as original-material fossils.
Fossil records are the fossils ever found or discovered on the earth.

Answer:
Decomposition reaction = Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .
Explanation:
Those reactions in which single compound decompose down to give two or more products are called decomposition reaction .
For the Decomposition reaction to take place , <u><em>a large amount of energy ias needed</em></u>. This is because for decomposition bonds are required to breaks. Hence energy is needed to break the bonds as they have strong force of attraction.
They occur in presence of HEAT , LIGHT , ELECTRICITY.
examples of decomposition reactions are:
Here only one CaCO3 is producing two substances which are : CaO and CO2
This is also known as decompositon of Calcium carbonate and it require a lot of heat energy.
This is also a decomposition reaction , This occur in the presence of sunlight
