Which of the following best explains one way that microorganisms contribute to maintaining the health of humans?
Microorganisms convert sunlight into glucose. Humans consume the glucose, an essential energy molecule needed in metabolic processes.
As microorganisms breakdown organic matter, they release nutrients into the environment that are essential for the growth of organisms that humans rely on for nutrients.
As microorganisms replicate, they produces hormones that are essential to human growth. These hormones are transferred to humans through the food we consume.
Microorganisms are decomposers and are needed to break down tissue after the human is dead.
Which of these best demonstrates mutualism between certain types of bacteria and humans?
Intestinal bacteria obtain nutrients from the gut and produce vitamin K used by humans.
Bacteria become resistant to antibacterial medication that humans use for treatment.
Invasive bacteria at an area of injury produce toxins that damage healthy tissues of the human body.
Bacteria in improperly prepared food is consumed by humans, causing food poisoning.
