:<br> The correct order of stages in primary succession of a volcanic island is
miskamm [114]

Answer:

Volcanic rock-lichen-mosses-sea grasses

Explanation:

Lichens are complex living beings that form a symbiosis of an organism formed by a fungus and an algae or cyanobacterium. They're known for interacting with volcanic rocks. Moss is a cosmopolitan phylum of small, simple-organized, and non-vascular cryptogamous plants that typically grow in dense tufts, which are more common in humid and dark habitats. They're the ones to come after the lichens during primary succession of volcanic island environments. Marine angiosperms, also known as, sea grasses, are the flower-producing plants adapted to life in seawater that form marine meadows on the euphotic bottoms of the oceans. They install themselves on the coasts that are populated by mosses, therefore not being uncommon to see in volcanic islands.

Galina-37 [17]

Nitrogen released from the breakdown of proteins is used in the synthesis of urea, which is excreted by the kidneys in the urine.

  • The urea acid cycle transforms the nitrogen waste released during this process into urea, which is then excreted in the urine.
  • Amino acids can be converted into energy during famine and go via the Krebs cycle.
  • Muscle protein is broken down into amino acids while fasting, some of which are partially oxidized to provide energy.
  • These amino acids are split up into alanine and glutamine, which are released into the circulation together with other amino acids.
  • Several tissues, notably the stomach and kidney, oxidize glutamine, converting some of its carbons and nitrogen to alanine.
  • The liver is where alanine and other amino acids are processed into glucose and ketone bodies and nitrogen.
