Answer:
nitrogen fixers------cyanobacteria
jellyfish--------------- nekton
zooplankton ----- phytoplankton
whales----------- nekton
Explanation:
Diatoms are single-celled algae that live in houses made of glass. They are the only organism on the planet with cell walls composed of transparent, opaline silica. Cyanobacteria is also called nitrogen fixers because cyanobacteria fixes atmospheric nitrogen in the soil in the available forms of nitrogen to the plants. Whales and jellyfish are nekton because they move in the water independently. Zooplankton feed on phytoplankton for gaining energy and survival.

Explanation:
The cycle of heating, rising, cooling and sinking is called a convection current. These currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over.
Answer:
heterotrophs
Explanation:
they cannot make food on their own.
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Hope this helps :)
