Autotrophs
Plankton and nekton are the two types of free-floating organisms. Plankton are small organisms that drift with the currents and include both phytoplankton (plant-like) and zooplankton (animal-like). Nekton are larger, more mobile organisms like fish and marine mammals that actively swim in the water column.
Plants and algae are two organisms that have chloroplasts. Chloroplasts are responsible for photosynthesis, the process by which plants and some microorganisms convert sunlight into energy.
Lichens are composed of a fungus and an alga or cyanobacterium living in a symbiotic relationship. The fungus provides structure and protection, while the alga or cyanobacterium provide photosynthetic capabilities to produce energy for the lichen.

Eubacteria is heterotrophic. But then there are two other types that are photosynthetic autotrophs, and chemosynthetic autotrophs.

Photosynthesis evolved multiple times in the history of life on Earth. It is believed to have evolved at least two separate times, leading to different types of photosynthetic organisms.
Metamorphic and Igneous are two types.

Phototrophs are organisms (usually plants) that carry out photosynthesis to acquire energy. They use the energy from sunlight to convert carbon dioxide and water into organic materials to be utilized in cellular functions such as biosynthesis and respiration. chemotroph are organisms that obtain energy by the oxidation of electron donating molecules in their environments. These molecules can be organic (organotrophs) or inorganic (lithotrophs). The chemotroph designation is in contrast to phototrophs which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic.
chemoautotrophs-those organisms that make their own food by chemical means, ie. without light. literally chemical-self-nutrition photoautotrophs-those organisms that use light to produce food to feed themselves, ie. photosynthetic organisms. literally light-self-nutrition
Freshwater protists with two flagella that can be photosynthetic or heterotrophic are called euglenoids. They are single-celled organisms that can switch between autotrophic and heterotrophic modes of nutrition depending on environmental conditions.

Diatoms are photosynthetic organisms with a glassy two-part cell wall made of silica. These cell walls, called frustules, have intricate patterns and are responsible for the diverse shapes and sizes of diatoms.
