Food enters the stomach during the third stage of digestion, hope this helps.
<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:
d. Species diversity
Explanation:
The species diversity can be measured by:
- Species richness: Refers to the number of species are inhabiting a defined area.
- Species abundance: Describe the distribution of the species abundance.
Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
