The researcher behind this outlined the benefits of using this food replacement for chickens in that it improved growth and wellbeing of the chicken. While this example is not a natural one, it does outline the use of algae as a food source for domestic chickens, an important consideration in the future of both algophagy and agriculture.
Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can't make their own food like Green plants. Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic.
If the heterotroph uses chemical energy, it is a chemoheterotroph (e.g., humans and mushrooms). If it uses light for energy, then it is a photoheterotroph (e.g., green non-sulfur bacteria ). Heterotrophs represent one of the two mechanisms of nutrition ( trophic levels ), the other being autotrophs ( auto = self, troph = nutrition).
Cats can eat most white fish and salmon, but it’s important to be wary of the risk of high mercury levels. Fish that are predatory, i.e., eat other fish, are more likely to have higher mercury ...

Some predatory algae have evolved extreme survival strategies. For example, Oxyrrhis marina can turn cannibalistic on its own species when no suitable non-self prey is available, [ 11 ] and Pfiesteria and related species have been discovered to kill and feed on fish, and since have been (mistakenly) referred to as carnivorous "algae" by the media.
Chemoautotrophs can use inorganic energy sources such as hydrogen sulfide, elemental sulfur, ferrous iron, molecular hydrogen, and ammonia or organic sources to produce energy. Most chemoautotrophs are prokaryotic extremophiles , bacteria , or archaea that live in otherwise hostile environments (such as deep sea vents ) and are the primary ...
Fleas, spiders, termites, flies, centipedes, ants, bedbugs, cockroaches — these icky intruders won't give up. But keeping them away doesn't require expensive chemical pesticides.
