the respiratory pigment in humans is hemoglobin

the bird eats the earthworm the earthworm nourishes the bird
To find out what an earthworm has been eating an examination of their droppings is needed. If the earthworm has been eating soil, sand will be present in the droppings.
a frog can be classified having gills and lungs tadpoles have gills while frogs[or adult]have lungs
The segment number of the pharynx on an earthworm is around 4-7. Hope that helps.

Earthworm are like human cause they have a complete losed circulatory system. The earthworm has red blood that contains respiratory pigment similar to hemocfokin. External respiration in human must be moist and an earthworm keep its body surface.
The metal component of a respiratory pigment is the part that actually binds to the oxygen molecule.
You DO find a respiratory structure in each segment of the earthworm. An earthworm uses its skin as the respiratory structure. Oxygen in the air dissolves in the moisture and mucus on the skin then diffuses into blood capillaries close to the skin to be transported to the rest of the body.

Haemoglobin is the respiratory pigmaent of blood in mammals

Blood lacks respiratory pigment.
This is because the earthworm takes in oxygen through its skin and releases CO2 through it's skin as well using diffusion
Reg blood cells contains the respiratoy pigment haemoglobin.
Actually, earthworms have no respiratory system at all, they get the oxygen and nitrogen that they need from the soil.
The earthworm has no special respiratory organs. Gaseous exchange occurs through moist skin by diifusion.
