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.
Hydra are heterotrophic organisms, meaning they obtain their energy and nutrients by consuming other organisms. They are carnivorous and primarily feed on small aquatic invertebrates like water fleas and tiny worms.
Some examples of organisms that reproduce by budding include Hydra, some species of fungi, and some types of bacteria such as Prochloron.
The green hydra (Chlorohydra viridissima) gets its colour from green algae which live inside its tissues in a mutually beneficial relationship. The algae living inside the hydra benefit from having a sheltered safe environment and obtain food by-products from the hydra. The hydra also benefit from algal products. from www.offwell.free-online.co.uk/hydra.htm Hydra eat one celled animals, small crustaceans, worms, insects and other tiny animals. They are also reported to eat small fish fry in the aquarium, where they do occasionally show up. Hydra have a saclike body and a circle of tentacles at around the body opening. This opening is used for both taking in food and eliminating wastes. from http://www.naturalaquariums.com/inverts/hydra.html So this would make them heterotrophs. AliceJM
Budding is a form of asexual reproduction in which a new organism develops as an outgrowth from the parent. It is commonly observed in organisms such as yeast, hydra, and some plants.
Small buds called basal discs are released from the base of a hydra to detach and move to another area. Basal discs allow hydra to reproduce asexually and establish new colonies in advantageous locations.
Hydra appear green due to the presence of symbiotic green algae called zooxanthellae or other chlorophyll-containing organisms within their cells. These algae perform photosynthesis, producing food for the hydra while also imparting a green color. The relationship benefits both organisms, as the hydra gains nutrients and the algae receive protection and access to sunlight. This symbiotic relationship is a key factor in the hydra's vibrant coloration and ecological success.

Hydra belong to the phylum Cnidaria and the class Hydrozoa.
Hydra do not have an endoskeleton. They are multicellular organisms that can be found in unpolluted fresh-water ponds, streams, and lakes.
Hydra are secondary consumers, primary consumers feed off of photosynthetic organisms. Hydra eat primary consumers like daphnia for example.
Hydra feed using stinging nematocysts to catch small aquatic organisms, most commonly, copepods.
A hydra depending on the species can be a multitude of colors, green is just the most common.
A hydra belongs to the biological domain Eukarya, which includes all organisms with cells containing a nucleus.
The hydra is classified under the phylum Cnidaria, which includes other organisms such as jellyfish and sea anemones.
Hydra are heterotrophic organisms, meaning they obtain their energy and nutrients by consuming other organisms. They are carnivorous and primarily feed on small aquatic invertebrates like water fleas and tiny worms.
The hydra makes offspring by forming buds that break off and grow into new hydras like the parent.
