Biology essay – Relationships and interactions
There are many different types of relationships and interactions between organisms. Every organism is in some way connected or associated with another. Some organisms need to depend on other organisms to survive which shows how important some of these relationships or interactions can be in biology. Interaction is a vital part of how many organisms develop over time.
Predation is a main example of a relationship between organisms. Predation involves predators and prey, such as a fox catching and eating a rabbit. There are two other forms of predation called, parasitism and grazing. Parasitism is where the host organism is exploited and used for benefit by the other organism called a

Lichens are another example of mutualism. Lichens are formed by algae and fungi living together and they both help each other. Algae can photosynthesise and make food, which is shared by the fungus. The fungus in turn shelters the algae from a harsh climate.
Commensalism is when one species can benefit from a relationship and not hurt the other. There are four different main types; chemical, inquilinism, metabiosis and phoresy. Chemical commensalism is most often observed between bacteria. It involves the species of one bacteria feeding on the chemicals produced or the waste products of the other bacteria. Inquilinism involves one species using the body of another organism as a platform or living space while the host does not benefit or is harmed. Metabiosis occurs when one species unintentionally creates a home for another species through one of its normal life activities. A phoresy takes place when one organism attaches to another organism specifically for the purpose of gaining transportation. An example of commensalism (inquilinism) is barnacles and whales. Barnacles are non-moving and they rely on currents to bring them food. Some barnacles attach themselves to whales in order to help them live. They can benefit as they are then transported over the ocean which exposes them to more feeding oppurtunities. The whale neither benefits or is harmed by the barnacles.
Competition is a huge
In this lab, we examined protist survival in different communities. An biological community is a community where two or more species coexist in
According to our text species of living things are related in some fashion similar to a branching tree. However the process is not quite that simple adaption relies on several processes and to prove this or the
Each organism fits into the food web because well something eats them and then that species that is being eaten will be eating another
Coevolution happens when two species evolve together because of the relationship they have with each other. For example, as prey gets faster to avoid being eaten, predators also have to be faster in order to eat. Coevolution can also happen between organisms with a relationship a mutualistic relationship as shown Figure 3. Pollinators, such as hummingbirds, have evolved beaks to feed on specific plants. The plants benefit because they are pollinated.
One example of cooperation is that of the queen trigger fish and the bar jack. Trigger fish feed on invertebrates like crabs, and shell fish, while the bar jack feeds on other fish. Becuase the trigger fish does not eat fish, other fish are not threatened by them. So the bar jack hides behing the trigger fish so it can get closer to its prey without being detected. A good example of competition is that of fighting corals. Because coral rely on sunlight, there is often competition between them for acess to this reasource. This can be seen in the DMZ's. These are areas were "corals have met, done battle, and withdrawn. This is an obvious space where neither coral ventures, having concluded that furthur conflict is not worth the cost."
Predator-prey interactions can be seen in multiple biomes for multiple organisms. Evolutionary responses have been introduced to both sides to better enable either hunting and/or survivorship. A good example of the latter of the two is the response of snails to predation by crayfish. When other snails are crushed and consumed, a chemical is released allowing other snails to avoid the area. This is known as a chemical refuge and is what our study is mainly focusing on.
In parasitism, the parasite benefits, but the host is harmed. Symbiosis is the close interaction between organisms of different species for an extended time. Symbiotic relationships differ on the effects of the “other” species while one benefits. The three major symbiotic relationships are commensalism, mutualism, and parasitism. In commensalism, the species benefits and the other remains unaffected. One example are barnacles hitching a ride on the skin of a whale. In parasitism, the parasite benefits and the host is harmed. The parasite lives on or in the host and benefits by feeding on it. An example of this are tapeworms that live inside the intestines of organisms. The organism is harmed, since they are not getting the nutrients from the food that they are eating, but the tapeworm benefits, as it is getting the food and nutrients it needs to survive. Tapeworm larvae can also migrate throughout the body, therefore harming other organs and tissues as well. In mutualism, both species benefit. One example are lichens, which are formed by fungi and algae living together. The algae undergo photosynthesis, which provides food, and the fungi provides
There are different types of how different species in our ecosystem wok together. Relationships doesn’t only occur in humans but also in animals. It my either be mutualism or commensalism, but it can also be parasitism. Parasitism is when one organism is taking advantage of another organism without their free will. It is a way to survive for the parasite to gain nutrients, or even shelter. Mostly all parasites are within an organism internal structure, making it impossible for the host to live their daily activities. Parasites may even be killing their host.
Symbiosis is the interaction between two different organisms living in close physical association typically to the advantage of
A Facultative relationship is when organisms live together by choice. There are many forms of symbiotic relationships, but the most common and relevant to this argument are mutualism, commensalism,
This informational video explains the term symbiosis. In the video, the narrator looks underwater to discover how symbiosis plays a role in aquatic animals. The video also uses animation to goes into in-depth details about mutualism, commensalism, and parasitism. The author also provided an image that gave an excellent summary of each type of relationship; by using the (-) sign to represent a harmful relationship, (+) sign to represent a beneficial relationship and (o) to represent a neither harmful nor beneficial relationship.

Symbiosis – What is It? Symbiosis describes a relationship between two organisms, and there are a variety of different symbiotic relationships that can be observed on the reef. They are:
Coevolution in this scenario occurs by selection for those organisms from both taxa which possess trait which allow them to take the best advantage of this mutualism relative to their conspecifics. An example of this relationship is the plant-pollinator interaction between yucca plants and yucca moths.
Mutualism is the relationship between two individuals of different species in which both individual species benefit. The aforementioned clownfish and sea anemone share a mutualistic relationship. The clownfish provides the anemone protection against anemone-eating fish and, in return, the anemone provides a home for the clownfish safe from predators. Commensalism is the relationship between two organisms of different species in which one organism benefits while the other is unaffected (Yukalov et al., 2012). An example of a commensalism interaction is that
