Anywhere the sun shines! Photoautrotrophs are anything that does photosynthesis, like plants and algae.
Bacteria, plants, algae and mushrooms are the organisms that are producers.
Algae are autotrophs, which means they produce their own food.
Autotrophs that utilize light as their energy source are called phototrophs. These organisms are able to perform photosynthesis to convert light energy into chemical energy for their survival and growth. Examples include plants, algae, and some bacteria.
Heterotrophs and Autotrophs
Yeast, mushrooms, and bread mold are all types of fungi. Algae, however, is not a fungi but rather a group of photosynthetic organisms that can belong to various taxonomic groups including bacteria, protists, and plants.
The main photoautotrophs in aquatic environments are phytoplankton, including diatoms and cyanobacteria. These organisms utilize sunlight to produce their own food through photosynthesis and form the base of the aquatic food chain.
Organisms that perform photosynthesis to make their own food include plants, algae, and some bacteria. They use sunlight, water, and carbon dioxide to produce glucose and oxygen as a byproduct in the process. This ability is what makes them autotrophs, able to sustain themselves without relying on external food sources.
Organisms that derive their energy from sunlight are referred to as photoautotrophs. They use the process of photosynthesis to convert sunlight into chemical energy that can be used for growth and metabolism. Examples include plants, algae, and some bacteria.
Examples of eukaryotes include animals (such as humans), plants (such as trees), fungi (such as mushrooms), protists (such as amoebas), and algae (such as seaweed).
a. Photoautotrophs. These are organisms like plants, algae, and cyanobacteria that use sunlight to convert carbon dioxide into oxygen through photosynthesis, which ultimately leads to the high levels of oxygen in Earth's atmosphere.
An autotroph is any organism that produces its own food. This is very rarely seen in animals, but is almost always seen in plants. In most cases algae is a plant, but in some cases it is also a type of bacteria. The bacteria are not auto-trophic, but they can be in some cases. MOST of the algae you will see in an aquarium or pond though is an actual plant, and the green color of plants is due to their cells containing "chlorophyll". Chlorophyll is used by plant life to convert sunlight and Carbon Dioxide (CO2) into food and Oxygen (O2). So this would make MOST algae you see an autotroph.
