grandymaker [24]

As we know 10% law is transfer of energy from higher trophic level to lower trophic level. So as the energy are transfer from one organism to another there is a loss of energy as that energy are utilised by the oragnism and only 10% of the total energy is transferred to the second consumer.

Explanation:

Quetinary consumer are at the higher position in the food chain so they do not get enough energy from prey they have to feed on several organism for the enegy. And also they are at the top of the food chain so they are not eaten by other animal, their life span are also more than primary consumer.

LekaFEV [45]

Answer:

Opportunistic, endogenous pathogen

Explanation:

Opportunistic infection is an infection that is caused by the microbes that are otherwise the component of one's own normal microbiota.  Under particular conditions, the microbes become pathogenic and cause infection. The pathogen-derived from one's own microbiota is called endogenous pathogen.

According to the given information, <em>Candida albicans </em>is a part of the microflora of mouth but becomes pathogenic under certain conditions. In healthy individuals, they do not produce disease as their overgrowth is suppressed by other microbiota and other host resistance mechanisms. The infection occurs only in those individuals with predisposing factors such as weakened immune system or after consumption of antibacterial medications that disturb the normal microbiota and immune competency. This makes it an opportunistic, endogenous pathogen.
