Amensalism -/0 interactions - : one species is harmed while the other is unaffected Tend to be more accidental than other relationships Example: a herd of elephants that crushes plants and insects while moving through a forest . Commensalism +/0 interaction: - one species benefits while the other is unaffected Brown-headed cowbirds follow grazing cattle and bison, foraging on insects flushed from the vegetation. Cattle convert plants into dung, which dung beetles can use. Dung beetles dispe...

Organic Nutrient An organism that contains carbon and hydrogen Inorganic Nutrient An organism that does not contan carbon and hydrogen Phototroph An organism that gains energy from light through photosynthesis Heterotroph An organism that must obtain carbon in an organic form - they are dependent on other life forms Chemotroph An organism that gains energy from chemical compounds - this means they eat things. Harvesting energy from the things they eat. Autotroph An organism that g...

Match each of the following organelles with the correct description. Ribosomes nucleus cytoplasm lysosomes Ribo - funtion in protein synthesis nucleus - contains genomic content cyto - constitutes the open volume lyso - contains hydrolytic enzymes Briefly explain how a Scanning Electron Microscope (SEM) forms an image of subcellular organelles, substrates, and viral particles.
