Food chain

Want the best food chain to feed america ? Want to be in control of what you eat ? Entering the hunter - gatherer food chain will satisfy you with being comfortable in what you eat. This food chain is not man made. The hunter is just a part of the food chain , like an animal. The hunter - gatherer food chain can be defined as the oldest type of food chain there is. It´s hardly a chain at all really. Hunter gatherers ate better , grew taller , lived longer and were healthier than “ civilized ¨…

organism's occupy within the food chain. There are generally five trophic levels: primary producers, primary consumers, secondary consumers, tertiary consumers, and apex consumers. These five levels all interact with each other to ensure bio-viability. The first trophic level contains the primary producers. They are called the primary producers because they produce their own food and energy. Primary producers include plants and algae, organisms that produce their own food and energy through…

Senn et al., 2010; Kwon et al., 2012; Das et al., 2009). The MDF and MIF signatures of food webs may help to identify major sources and processes leading to significant bioaccumulation of MeHg (Perrot et al., 2012). To the best of my knowledge, there is no feeding experiment mimicking high Arctic marine ecosystem to study Hg transport, transformation and change in isotopic (both MDF and MIF) composition in food webs.…

For my project, I chose to make an illustration. In the picture I have a breast cancer ribbon, a pot of boiling water, a prokaryote, a chromosome, a pedigree, and a factory to represent human impact, a flower to represent photosynthesis, a food chain, an energy pyramid, an embryo, humans evolving, a biomolecules chart, and the phases of mitosis. I drew a breast cancer ribbon because we talked about different types of cancer. There are many factors that go into the diagnosis of cancer. A lot of…

Zooplankton are an important part of the food chain and their decline can lead to a change of organismal relationships (Mahassen, El-Deeb Ghazy, 2011). Daphnia, a type of zooplankton, are at the bottom of the food chain in freshwater systems. If toxicity of the water is too high, it can affect these organisms, which will then affect others in the food chain (Ebert, 2005). Changes in the pH levels affected motility strength of Daphnia. There was a…

How does food web complexity affect the biodiversity of an ecosystem? Before we were given the question, we were taught that biodiversity is about relative abundance and species richness. Just recently we learned about the transfer of energy in food webs, while also learning more about trophic levels. Looking at how much energy you gain and how much an organism needs, I learned that eating straight off a source of plants would help organisms grow and prosper. For our group we examined the…

“Poach the Poachers” Did you know that since 1960, the black rhino population has decreased by 97.6% due to poaching. This is according to the African Wildlife Foundation who is trying to raise efforts to bring attention to the serious danger some animals are in, and the culprit for these animals nearing extinction is in fact humans. For many years the human species has been killing off animals for sometimes no other reason than the thrill they feel when they are hunting down one of these…

interactions of the animals. {draw:frame} If there is excessive noise pollution, animals within the network which depend on hearing to locate their prey may have extreme difficulties. Because of this, the organism will struggle to locate its food source, or companion, causing a lower chance of survival. Also, excessive and ongoing noise pollution will cause communication issues between a certain species, therefore disrupting their natural breeding patterns. If noise is not…

feeding position in a food chain such as primary producers, herbivore, and primary carnivore. Green plants form the first trophic level, which are the producers. Herbivores form the second trophic level, while the carnivores form the third and fourth trophic levels. A food chain is the feeding of one organism upon another in a sequence of food transfer. Another definition is the chain of transfer of energy, which typically comes from the sun, from one organist to another. All food chains start…

the elimination of wolves was seen as an object of concern because now that there would be no more wolves to feed on the elks, the willows stared to slowly decline. The willows are important to the ecosystem because they serve as the basis of a food web/chain with small insects, birds, mammals, fungi and bacteria. Beavers for example depend highly on the willows because they use them for dams and lodges. Next, the beavers provide a pond to many reptiles and amphibians. In return this increases…
