Answer:
microfilaments
Explanation:
Cytoskeleton are made of three main filaments including actin filaments, microtubules and microfilaments. Microfilaments are flexible double strands of the protein actin that are of different proteins which give mechanical support. Important functions include:They lead the intracellular movement of organelles and molecules
.They stabilize mechanically the plasma membrane.
Herbivores are primary consumers.
