Parasitism
Explanation:
This relationship in which the heartworms gets nutrient from the host and in the process, the host eventually dies from infestation is known as parasitism. 
- The organism that houses the heartworm is called the host 
- The heartworm in itself is called the parasite. 
- Parasitism is a positive - negative relationship in which one organism feeds on the other and causes harm to it in the process. 
- Plasmodium falciparum is the parasite of malaria in man. 
- In commensalism, one organism depends on the other without causing harm to it. Example is cattle and egret. 
- Mutualism is a positive - positive relationship in which both organism derives benefits from the other. Example is lichen.

Three examples of marine genetically engineered organisms are:
1.	AquAdvantage salmon  is genetically engineered Atlantic salmon modified in order to achieve fast growth. A growth hormone-regulating gene of Pacific salmon is introduced in the genome of Atlantic salmon.
2.	Grass carp was also modified by scientist in order to enhance its protection from contagious diseases. It has been modified with a transgene coding for lactoferrin (antibacterial function). So, the, survival rate of the modified Grass carp was doubled comparing to nonmodifeied fish.
3.	Zebrafish is the most commonly used for modification because it has 1-cell embryo, with clear chorion so it is easy to be micro-injected with transgenic DNA.
