Echinoderms, like chordates, are deuterostomes and are therefore thought to be the most closely related of the major phyla to the chordates
Just as they do in most ecosystems, decomposers feed off of dead or decaying matter, recycling it back into the ecosystem for plants to receive essential nutrients and to.. basically, de-clutter the world.
Answer: The correct answer is cortex
Explanation:
The glomerulus and the bowman’s capsule are both located in the Cortex, one of the two main regions of the kidney, alongside the Medulla.
The glomerulus is a mass of blood capillaries linked to urinary tubule, while the Bowman's capsule is a cup-shaped structure. The glomerulus filters materials such water, urea, glucose ET into the bowman's capsule in a process called ultrafiltration, a necessary step in urine formation.
