Paragraph based question Read the following paragraphs and answer the questions based on it. After the death of apex consumers, their energy becomes available to the decomposers. Fungi and other micro-organisms decompose the bodies of dead animals. They are called decomposers. In the process of obtaining food from the remains of organisms, decomposers convert them into simple carbon compounds. These substances easily mix with air, water and soil from where they are again absorbed by plants and incorporated into the food chain. Name the decomposers. Where are they found?

The countries which do not have oil reservoirs in their land import oil from other countries. But sometimes during transporting oil through sea routes, accidental oil spilling occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removel of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp. and Alcanivarax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction carbon with oxygen resulting in formation of CO_(2) and water. Like oil spills cause damage to aquatic life. plastic forms the major part of the garbage on land. Plastics are difficult to degrade as they are made up of PET. By research, various species like Vibrio and Idenoella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage. Based on the given paragraph answer the following question. Which type of chemical compounds are degraded by microbes used for clearing oil spills ?
