Answer:
parasitism
Explanation:
In evolutionary ecology, parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.
Alcoholic fermentation occurs in yeast and produces ethyl alchol from pyruvate.
Lactic acid fermentation occurs in animals and produces lactic acid from pyruvate.
Both of these processes can proceed in the absence of oxygen.
Because, photoautotrophs serves as their carbon sources.
Chemoheterotrophic bacteria are those bacteria that are incapable of producing their own food, they depend on photoautotrophs, which are capable of making their own food by trapping energy from the sun. Thus, photoautotrophs serves as source of food for the chemoheterotrophic bacteria.
D because all the other answer are negative feedback
