Answer:
A) ? I would assume this because the plasmid lacks the fragment.
Organisms that digest molecules in organic material and convert them into inorganic forms are called decomposers. They are classified as heterotrophic since they use organic substances in obtaining the energy and nutrients they need to survive. They are organisms that are responsible for breaking down decaying organisms into simple molecules in order to bring these back to the biogeochemical cycles into the ecosystem. In the food chain, they are the last step. Examples of these decomposers are fungi, snails and some insects. These organisms do not have an internal digestive organs since the the organic substrates undergo biochemical reactions only.
A is volcanoes. They are formed by molten rock emerging through cracks or weaker areas in the crust of the Earth, the molten rock then cools into solid rock. This happens several times and the volcano gradually builds up in many layers, sometimes (like in the photo) this is enough for the volcano to break through the surface of the water e.g. Hawaiian Islands.
