a) Convert organic material to inorganic forms.

Decomposers are organisms that play an important role in the process of decomposition, which is the breakdown of organic matter into inorganic compounds. Decomposers include bacteria, fungi, and invertebrates such as worms and beetles. They are found in all ecosystems and play a vital role in the cycling of nutrients and the maintenance of the balance of matter in the environment. Decomposers break down organic material, such as dead plants and animals, into simpler, inorganic compounds such as carbon dioxide and water. They do not convert inorganic materials into organic compounds or convert inorganic material into simple forms.

Read the information given below carefully and answer the following question.The whole biosphere, like the individual organisms that live inside it, exists in a chemically dynamic state. In this homeostatic system, a great number of organic compounds are synthesized, transformed, and decomposed continuously; together, these processes constitute the major parts of the carbon cycle. For the smooth operation of this cycle, degradation is just as important as synthesis: the green plants produce great quantities of polymers, such as cellulose, and innumerable other compounds like alkaloids, terpenes, and flavonoids, that green plants cannot use as sources of energy during respiration. The release of the carbon in these compounds forrecycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi. Some bacteria and fungi possess the unique and extremely important biochemical asset of being able to catalyse the oxidation of numerous inert products, thereby initiating reaction sequences that produce carbon dioxide and so return much carbon to a form that actively enters into life cycles once again.Q.The author implies that which of the following is the primary reason that degradation is as important as synthesis to the smooth operation of the carbon cycle?

A species that exertsan influence out of proportion to its abundance in an ecosystem is called a keystone species. The keystone species may influence both the species richness of communities and the flow of energy and materials through ecosystems. The sea star Pisaster the flow of energy and materials through ecosystems. The sea star Pisaster ochraceus, which lives in rocky intertidal ecosystems on the Pacific coast of North America, is also an example of a keystone species. Its preferred prey is the mussel Mytilus californianus . In the absence of sea- stars, these mussels crowd out other competitors in a broad belt of the intertidal zone. By consuming mussels, sea star creates bare spaces that are taken over by a variety of other species. A study at the University of washington demonstrated the influence of Pisaster on species richness by removing sea stars from selected parts of the intertidal zone repeatedly over a period of five years. Two major changes occured in the areas from which sea stars were removed. First, the lower edge of the 46. mussel bed extended farther down into the intertidal zone, showing that sea stars are able to eliminate mussels completely where they are covered with water most of the time. Second, and more dramatically, 28 species of animals and algae disappeared from the sea star removal zone. Eventually only Mytilus, the dominant competitor, occupied the entire substratum. Through its effect on competitive relationships, predation by Pisaster largely determines which species live in these rocky intertidal ecosystems.Q. Consider the following assumptions:1. The food chains/food web in an ecosystem are influenced by keystone species.2. The presence of keystone species is a specific characteristic of aquatic ecosystems.3. If the keystone species is completely removed from an ecosystem, it will lead to the collapse of the ecosystem.With reference to the passage, which of the above assumptions is/are valid?
