Why is the action of phagocytes considered a nonspecific response?

Since phagocytes are effective against any type of infectious/toxic agent.

Explanation:

Phagocytes are the cells of the immune system that are involved in the non-specific immune response. These cells serve to engulf and kill any pathogenic or infectious microbe that has entered the body. Since phagocytes do not require the presence of specific antigens or pathogens to mount the immune response, their action is "non-specific response".  

D. It is not a response to a specific type of pathogen.

Explanation:

this is the answer to this question on edge2021 :)

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
