<span>no because organisms such as humans are omnivores they can eat both meat and plants and may act as 1st,2nd or 3rd level heterotroph.</span>
<span>Endospore is a protective structure that can
able to survive for long periods of time in soil and water in which they commonly
found. They are tough, dormant and non-reproductive structure which can
withstand heat, dryness, and toxic chemicals that would kill most other
bacteria produced by a small number of bacteria like the bacterium Bacillus
thuringiensis from the Firmicute family. To ensure the survival of a bacterium
through periods of environmental stress is the primary function of most
endospores. They are also resilient to gamma and ultraviolet radiation, chemical
disinfectants, desiccation, starvation, lysozyme and temperature and can survive any environmental assaults.</span>
