can be photosynthetic
A
algae
B
fungi
C
bacteria
D
helminths
Explanation: 

Detailed explanation-1: -Photosynthesis is the biochemical process by which plants, algae and certain bacteria can convert the sun’s energy into chemical energy in the form of carbohydrates.

Detailed explanation-2: -Green algae, diatoms and dinoflagellates are the most well-known, though other microalgae species include coccolithophores, cryptomonads, golden algae, yellow-green algae and euglenoids 1. There are so many diatoms drifting in the oceans that their photosynthetic processes produce about half of Earth’s oxygen 9.

Detailed explanation-3: -Photosynthesis is the process by which light energy is converted to chemical energy whereby carbon dioxide and water are converted into organic molecules. The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella.

Detailed explanation-4: -Red pigment allows the red algae to photosynthesize at deeper depths than the green or brown algae, harnessing more of the blue light waves that penetrate deeper into the water column. Unlike green algae and plants, red algae store carbohydrates as Floridean starch in the cytosol.

Detailed explanation-5: -Both Prototheca and Helicosporidium are non photosynthetic, and since most phylogenetic analyses have depicted Helicosporidium and Prototheca as members of a monophyletic clade, it is hypothesized that the loss of photosynthesis represents a synapomorphic character for these algae.
