Hello, I’m not sure if this is biology or chemistry or oceanography or what. I’m not much of a science person. I’m also going to preface this by saying i have anxiety and it’s causing a dumb anxiety attack for me so sorry if this doesn’take sense.
As far as i can tell, oceans and land like to work in cycles, to deliver the necessary building blocks of life. water cycles and the migrations of animals mean that nutrients cycle between the two. The carbon, nitrogen, phosphate and so on in my body will decompose into the soil, and then rain will carry it into a river. It will be swept into the sea. Somehow, it will end up in a salmon eventually and be carried up the rivers back into the land. I’m not super technical, but basically the food chain is actually a cycle but on a larger scale. it’s poetic and comforting that things cycle like that.
But when a whale falls all the way to the bottom of the ocean and is eaten by deep sea animals… I don’t know how the cycle moves those nutrients back up onto the surface and then land. As far as i can tell, those animals don’t interact much with the middle of the water Column so it’s not super common for them to then be eaten by other animals from the coastal areas. Maybe sperm whales versus squid? How do the nutrients consumed by the hagfish return to the cycle and then end up in like. A tree. A cow. Me? I’m missing the links in the food chain and i can’t find it on the internet.

Generally when whale dies it’s corps support whole ecosystems, and can take years to decompose. First, large scavengers will feed on it, and those will be on or near the surface, then small bits and pieces will start falling down and support deep ocean ecologies, but we don’t truly understand those. Depending on how deep you go, they will feed anything from fish to microbes, and entire deep ocean ecologies rely on decomposing animal bits falling to ocean floor.
