Essay on Food Web Case Study

One of those relationships, food webs, has an important function of transferring energy and keeping the biological lifecycle going by the various lifeforms feeding off one another. The concept of energy transfer that goes on in food chains in ecosystems keeps organisms living by the energy the body needs being provided when they eat other organisms, as supported by the studies of “food chains, food webs, and trophic levels.” It is important that we continue to observe ecosystems like the Everglades Hardwood Hammock in order to help preserve them. (Arms,

The organisms found in temperate forest ecosystem are trees: producers, plants: producers, insects: consumers and decomposers, squirrels: consumers, deer: consumers, bears: consumers, foxes: consumers, and birds: which consumers and decomposers. The rewards of this biodiversity are the survival of life is certain and will maintain to live in connection with the organism. Essential nutrients are supplied by plant life eaten by herbivores that are then eaten by carnivores, which keep the food chain going. Producers, consumers, and decomposers are the major three categories of organisms found in the temperate forest system. Producers consists of trees,

The connection The Good Food Revolution tries to also make is between ecology and human development. Ecology is about dealing with relations of organisms to one another

An ecosystem is a community of interacting organisms and their environment. If one of the organisms is disturbed, it can change the trophic cascade which is a sequence of impacts down the food chain. Hannibal supports this statement by writing “keeping these connections going ensures healthy, functioning ecosystems, which in turn support human life.”(578) An example of this is if all of the beavers died the other organisms would go somewhere else or die due because they no longer will have dams to support their ideal habitat.

Earth’s vegetation and animal life are all part of an intricate “web” of essential relations in which both cannot survive without the other. According to Campbell’s Biology textbook, The transfer of food energy up the trophic levels is referred to as a food chain. This chain usually begins with plants, (primary producers), then herbivores, (primary consumers), to carnivores (secondary, tertiary and quaternary consumers), and finally decomposers. When one part of the chain is low in population, the species above it are likely to be negatively affected and will likely drop in population as well. In order to show how delicate this web is, and how human activity has affected this system, Carson describes a small food chain in which sagebrush

As the energy moves through the system, nutrients also travel through the levels of the food chain through the predator prey feeding cycle active in the food chain. To summarize the nutrients are cycled through the food web and the energy is not.

Leopold’s land pyramid describes the hierarchical dynamics of the biotic community. Based upon what we learned in class, a biotic community is the relationship between soil and animals. It is a sum of all the parts within the community. The pyramid represents layers within the biotic community. The bottom layer is the soil. A plant layer rests upon the soil layer, an insect layer lies atop the plants, a bird and rodent layer rests upon the insects. The pyramid works its way up the various animal groups until it finally comes to the peak layer, which consists of the lager carnivorous animals. Leopold places humans in the top layer.

Of the primary producers found in this environment, probably the one with the biggest impact on the ecosystem is grass because the blades feed the primary consumers who then feed the rest of the food chain. Although other plants also fulfill this function, grass is eaten in the most abundant quantities and also grows the most.

By definition, an ecosystem is a “community of organisms in an area and the physical factors with which those organisms interact.” Although the key characteristics of an ecosystem are the presence of biotic and abiotic factors, it is the interactions that enables vivacious life to flourish. Whether it is the isopods hidden in the nook under a log or its crustaceous ancestors in the vast ocean, ecosystems are thriving with behavior as its driving force. Effective communication can be observed in countless organisms, which is a testimony to its importance.

The tundra is an ecosystem that has consumers, decomposer, food chain and producers so that is the stuff that I know about tundra ecosystem so let's get started with The tundra ecosystem facts about the tundra ecosystem.

Next, primary consumers such as snails and weta eat producers, consuming their nutrients. Secondary consumers, such as Kereru, Tui and Long Tailed-Bats then consume these insects, with energy passing through the food chain to them. Tertiary consumers - such as stoats and possums - are pests to our native species as they are threats to populations of our native birds.

2. Humans belong to the consumer level, both primary and secondary and beyond which means we are considered omnivores that eat plants and animals. Humans and other animals can belong to more than one trophic level. Depending on what you eat and what you can eat, you may be placed in a different level depending on the circumstance. Organisms of different different metabolisms and lifestyles may be on the same level, thus trophic levels cannot indicate characteristics of organisms in a certain level. As organisms mature, they may change their feeding habits which cannot be classified under one level. In general, trophic levels generalizes ecosystem relationships because they cannot be diagrammed.

The organisms listed above are all related through a food chain. The partial food chain shown begins with the algae. Algae are producers that make their own food through the process of photosynthesis. Through photosynthesis they absorb nutrients within the water, which can then be consumed by other aquatic life like zooplankton.

Defining the system asa balanced ecological network; because the farmers don't feed the fish. Rather, the fish are eating what they'd be eating in the wild. Although, the farm loses 20% of its fish and fish eggs to birds, who thrive in these wetlands, the fish farmers don't mind because their farm thrives, not in spite of the birds, but because of the birds. Barber recommends to look "to farms that restore instead of deplete... farmers that are not just producers but experts in relationships… are experts in flavor too." In the end, we all want food that is not only ecologically and ethically sound, but delicious too (Mellino,2015). These chefs and experts are more cautious about what is happening to our supplies so they are one of the first finding solutions to the

Without photosynthesis we would not be able to receive energy. We should be more appreciate of plants, without them we would not survive. This paper will explain the basic components require for photosynthesis, the role of chlorophyll, how energy is transferred, and photosystems I and II and the most precious product results of photosynthesis.
