Answer : chemosynthesis and marine snow

Explanation :

Chemosynthesis is a process in which an organism instead of utilizing the energy of sun utilizied another source of carbon such as methane for production of food.

Since, in deep sea the sunlight is not able to penetrate there, instead of photosynthesis, chemosynthesis takes place.

Marine snow is the process in which the upper layer of detritus falls down from the upper layer of water column.

Marine snow is considered to be an important source of food for organisms living at the bottom of the ocean.
Thus, marine snow and chemosynthesis are the two processes that are an important source of food for deep sea organisms.

Where are mid-ocean ridges found? What do the mid ocean ridges tell us about plate motion?

REY [17]

Answer:

Mid-ocean ridges are found in the sea floor at divergent boundaries because both plates are moving away from each other creating the opening for the lava to sleep up. Mid-ocean ridges are where sea floor spreading occur by lava seeping up to the surface of the opening and cooling therefore forming new ground and pushing older layers of ground further away.

A 1-day-old infant in the shadow general hospital nursery has a yellow tint to the skin. what is this called?

never [62]

Jaundice is a condition that causes the skin of a newborn baby to turn yellow. This happens so because babies are born with extra red blood cells. After birth, the extra red blood cells break down and release a substance called bilirubin in the baby's blood. When there is too much bilirubin in the blood, the baby becomes jaundiced. This condition may last for 3-12 weeks after birth, but as long as bilirubin levels are monitored and the baby is feeding well, it rarely leads to any serious complications.
