Hydra's live sybiotically with Chlorella(Green Algae). The Chlorella provides food for the Hydra and is still alive, this explaining the green pigmentation in Certain Hydra's.

A hydra removes undigested food the same ways it takes in food. A hydra takes in it's food through it's tentacles, so it removes food the same way because it's like a pipe stuck in the ground and there is only one way in and one way out.
Since Hydra is part of the group of cnidarians, it is a bit more complicated than a sponge. The way that hydra digest their food is through extracellular digestion. This means that hydra actually have a special gut cavity that traps and digests food instead of having a bunch of cells do it, like a sponge. This gut cavity only has one opening and during digestion, enzymes from the cell wall are released to aid in breaking down the food. Once digested, the food is engulfed by cells from the wall into tiny particles through a process called Phagocytosis.
Asexually, through a process known as budding.

Step 1, A budd, looking like a bump will appear onto the adult hydra. Step 3, Tectancles that look like long strains will help the new to be hydra get food. Step 4, the new hydra will depart from adult hydra and will start it's journey by it's self. I am sorry I do not know step 2. Step 1, A budd, looking like a bump will appear onto the adult hydra.

Hydra are invertebrates. They have no back bone/spinal column.
