Question

Q8. Putrefying organisms are 1. Producer organisms 2. Reducer organisms 3. Consumer organisms 4. Parasitic organisms Q9. The most important organisms for an ecosystem are 1. Herbivorous 2. Carnivorous 3. Green plants 4. Protozoa​

Answer 1

1, Producers are organisms that produce food for themselves and other organisms. They use energy and simple inorganic molecules to make organic compounds. The stability of producers is vital to ecosystems because all organisms need organic molecules. Producers are also called autotrophs

2,Sulfate reducers are highly specialized microorganisms that can use sulfite, thiosulfate, and sulfur as a terminal electron acceptor for energy metabolism. The sulfide produced is a potentially corrosive element that can affect the integrity of metal containers in deep repositories

3,The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers.

4,A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Entamoeba histolytica is a protozoan. A microscope is necessary to view this parasite.
