Answer:

Decomposer

Explanation:

Decomposers are the heterotrophs that feed on dead and decaying bodies of living beings. During the process, decomposers break down the complex organic materials present in the dead and decaying matter into the simpler elements. These simpler elements are then released into the environment. Decomposers serve to recycle the matter back into the food web and biogeochemical cycles and do not allow it to be trapped in the dead and decaying matter.

A simplified food web illustrating a three-trophic food chain (producers-herbivores-carnivores) linked to decomposers. The movement of mineral nutrients through the food chain, into the mineral nutrient pool, and back into the trophic system illustrates ecological recycling.

The process of phagocytosis involve all of the following except

evablogger [386]

Hello, I figured your question was missing its options so I went online to find them. Here they are:

The process of phagocytosis involves all of the following EXCEPT :

a. adhesion.

b. secretion of cytotoxins.

c. elimination.

d. vesicle fusion.

e. chemotaxis.

Answer:

The correct answer is: b) secretion of cytotoxins.

Explanation:

Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.

Phagocytosis consists of many steps:

activation - the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
chemotaxis - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
adhesion - the phagocyte attaches to the pathogen.
ingestion /vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.

The secretion of cytotoxins is not a part of the phagocytosis, and is a process exclusive to T cells (leukocytes that lack the ability to phagocyte).
