A food web is a type of graph that depicts the relationship between the prey and the predators, also known as a system of food chains and how one another are related. This can be better explained as a connection in a community. Food webs are important because it is a direct illustration of the relationships among certain species within a certain community.
Right away the graph will reveal the type of species, what they interact with, the structure in which the environment they are located, and show the relations between each species. Because it is called a food web, the name has already shown that the relationship that will be represented will be a relationship concerning food. Within any given food web, there can very possibly be more than one food chain located inside of the actual food web itself. The different types of food webs will pertain specifically to that environment only. Ecological interactions determine flow of the food web.
Food webs will vary from simple to complex dependent on the type of food web being viewed. Competition Animals need air to breathe as a source of food, to eat to provide certain minerals to provide some of the body’s needs and to drink (BioTopic.com, 2014). Because the needs vary from one species to another, there comes the need to compete for many things for the need to survive. Even if this means that the species themselves are considered part of the food web as a meal for a larger species. With not only the competition to survive to make it out alive through another day, there is the need to create a family and also find a safe place to live (BioTopic.com, 2014).
Because these animals have mates to take care of, children to feed, and the need to protect what is theirs comes a whole new definition of the word competition. Many competitors within the food chain can at times be after the same types of food, searching for the same type of shelter can cause issues between not only species, but the living organisms that thrive within these eco systems like plants. Plants are also in need of resources (BioTopic.com, 2014).
Although their needs will differ from most animals, they are constantly in need of oxygen during daylight hours. Oxygen for plants is a source of nutrients and energy that allow them to grow and thrive. Boxicity Tropic Status Trophic levels depict how the producers, carnivores, and the herbivore have similar yet different types of feeding positions. The First level consist of the plants, the second level consist of the herbivores, carnivores are definitely in the third level and sometimes the fourth. When one species or organism is located in the food web, they are ultimately participating in food transfers.
Which is food chain going from species to species, or organism to organism. Rose Plant >Aphids >Beetle >Chameleon >Hawk (Bcb. com, 2014). The example listed here is a wonderful example to use because it displays one organism eating one other.
Real Life Applications The image above is also a true world depiction that corelates a described multi chart that is the food web to a real world situation to better understand the relations in a mathematical way.
