Compare And Contrast Autotrophs
1. What are prions and satellite viruses? Prions are groups of noncellular infectious agents, but are not viruses. In fact, they are naked protein molecules that lack nucleic acid. The diseases associated with prions are called Transmissible Spongiform Encephalopathies or TSEs. These diseases spread from host to host through direct contact or through the contamination of food. Satellite viruses are viruses that depend on other viruses to replicate. An example of this is the adeno-associated virus or AAV which can only replicate in cells that have already been infected with the adenovirus.

Compare and contrast autotrophs and heterotrophs. Autotrophs are organisms that can transform simple inorganic substances like CO₂ into nutritional organic substances. They are not nutritionally dependent on other living organisms. They get their energy from one of two possible non-living sources which are sunlight and simple chemicals that react with one another. Photoautotrophs are photosynthetic. They collect light as well as use energy to convert CO₂ into simple organic compounds. Heterotrophs obtain their carbon from an organic source and because organic carbon comes from other life sources, it makes heterotrophs dependent on other life …show more content…
Psychrophiles cannot grow above twenty degrees celsius meaning they cannot survive in the human body nor can they cause infection. Psychrophiles are usually found in snowfields, polar ice and even in the deep ocean. Mesophiles grow at intermediate temperatures between the range of twenty to forty degrees celsius. They inhabit animals and plants and can also be found in soil and water in temperate, subtropical and tropical regions. Mesophiles can also grow well in the human body. Thermophiles are microbes that grow optimally at a temperature greater than forty-five degrees celsius. Thermophiles can be found in soil and water associated with volcanic activity, and in compost piles and habitats exposed to direct sun. Most do best from forty-five to eighty degrees celsius. There are even a few bacteria and archaea that are called hyperthermophiles which grow best between eighty and one-hundred and twenty one degrees
