[Biology Class Notes] on Types of Relationships Between Organisms Pdf for Exam

All organisms are in a whirl with the ecosystem. The organism forms a type of relation for resources, some compete with each other, and some depend on each other for space or livelihood. These characteristics are divided into four parts: mutualism, predation, commensalism, and parasitism. With symbiosis, both organisms benefit from the relationship. With commensalism, one organism benefits and the other organism is neither helped nor harmed, sort of like neutral. With parasitism relationships, one organism benefits while the other organism is harmed, and there are two types underneath it: ectoparasites and endoparasites. With predation, one organism kills and eats other organisms. Some organisms live in very close symbiotic relationships with each other, which means one or both rely on the other for survival. 

For example, the cat is the predator and the bird is the prey. The predator is the cat, one who kills and eats; the target is the bird, one who gets killed and eaten. Any animal that hunts other organisms down, kills, and eats them for survival is known as a predator. This process is called predation. 

Interactions Between Organisms

Animals live in an array of populaces having, at any rate, two distinct species who are in constant interaction with one another, either directly or indirectly, inside a particular geological district in a natural network. The interaction between the species shapes the reason for some organic procedures in biological systems, for example, the evolved way of life and the nutrients cycle. 

The idea of these interactions relies on the environmental conditions and evolutionary angles wherein they exist. There are a few characterizations of these interactions which are found in various environments. These interactions can be utilized as a framework in dissecting the environmental network to depict forms that normally happen, which can thus be utilized to anticipate human modifications that may influence the properties and procedures of biological systems. These interactions can be between specific (interactions with various species) or intraspecific (interactions between same species). In this article, we will learn about the types of relationships between organisms and the interactions between organisms in detail.

Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed and, in some cases, may die. Take a look at some examples; mosquitos show up at most picnics and have a meal at your expense. Mosquitoes are carriers of some of humanity’s deadliest illnesses. So, the mosquito gets a meal, and you may get sick. In a similar fashion, ticks will do the same to you, dogs, or even livestock. They latch on their hosts and start eating, which can infect their hosts with many diseases, including Lyme disease. Many worms are parasitic, and a leech is a segmented worm that attaches to a host like you and gets a meal from your blood; they secrete a chemical that actually prevents the blood from clotting. If present in great numbers, besides being debilitating, in extreme cases, may even cause death.
