<span>When classifying organisms like this, you are looking for two main descriptors of their lifestyle: how they get their energy and how they get their carbon. A phototroph is an organism that acquires its energy through harvesting photons. A chemotroph harvests energy from chemical bonds.
The term heterotroph is used to describe organisms that acquire carbon from organic substances (namely from other organisms). An autotroph is an organism that has the ability to fix atmospheric carbon CO2 into an organic form.
When you combine these terms, you get a word that describes how an organism harvests energy and carbon. So, a chemoheterotroph is an organism that acquires energy from chemical bonds, and uses acquires organic carbon from an external source (usually, in this case, the energy and carbon come from the same source, e.g., glucose). A photoheterotroph is an organism that gains energy from photons but gains carbon from an external organic source.
Most bacteria, fungi, and animals can easily be described as a chemoheterotroph. A specific bacteria would be Pseudomonas aeruginosa.
Photoheterotrophs would only be found in the prokaryote domains. An example would be Heliobacter. Just to note, there are very few genera of photoheterotrophs. Remember, they gain most of their energy from light (photons), and their carbon from an external organic source (i.e., they do not fix carbon).
</span><span>Basically, photoheterotrophs get energy from light and chemoheterotrophs get energy from breaking chemical bonds.

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
Answer:
All is in order.......
stimulus is a thing or event that evokes a specific functional reaction in an organ or tissue.
homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Irritability is that characteristic of living organisms in being aware of, and being able to respond to, a stimulus which tends to disturb the steady state or homeostasis which all organisms prefer for maintaining life.
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

Answer:
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Explanation:
Answer:
It is known as a parasitic relationship.
Explanation:
Parasitic relationships are exactly what you described. We see these sorts of relationships in nature in worms for instance.
When a worm attaches to a host, it oftentimes leeches off the host's blood for nutrients and the like. In this manner, the worm benefits while the host gets weaker and loses nutrition.
Other examples include ticks and leeches.
