Amensalism
Figure 1. Penicillium.
Amensalism is the symbiotic relationship among organisms of two different species where one of the organisms is inhibited or eradicated, whereas the other is unharmed.
There are two basic modes of amensalism:
Competition
This occurs when bigger or stronger organism bareaves a smaller or weaker organism from a habitat or deprives it of its needed provisions
Antibiosis
This occurs when one organism is unharmed, but the other is impaired or destroyed by a chemical leakage
Example: Figure 1.
The bread mold penicillium conceals penicillin, a chemical that eradicates bacteria.
This is a form of amensalism as the bacteria is exterminated while penicillium is unharmed.

Endosymbiosis [ˈendōˌsimbēˈōsis]
Endosymbiosis is the symbiotic relationship that occurs when one of the symbiotic organisms live inside the other's body or cells. Most of the time, the interacting organisms cannot exist without one another; therefore they are considered obligate.
For example, the relationship between the mitochondria and chloroplast is a form of obligate endosymbiosis.
Ectosymbiosis
Ectosymbiosis is symbiotic interaction where the symbiont inhabits a part of the external body surface of the host.
