Factors That Affect The Food Chain

What do you think of the American food system? Do you think America is doing it’s best to feed you healthy food that’s safe for consumption?

The aim of the experiment was to find out how changing the mass effects the rise of the temperature of water.

This lab was about how a goldfish’s breathing rate changes in different temperatures in order to maintain homeostasis.

Climate change has affected us in many ways, but it was even more influential on organisms and their community. The Earth is gradually heating and we are left to deal with the consequences. Homes are being destroyed, organisms are dying, and resources are running low. Since 1880, Our Earth’s temperature had increased by about 0.8 degrees Celsius. Climate change is affecting the Earth and scientists say that one more degree will greatly affect people from all over the world. There are many consequences of climate change and each one has a great impact on all of us, but organisms’ homes are being destroyed and thousands of species are dying out. These organisms are imperative to our world and how it functions.

Planarians are hermaphrodites and have both the male and female organs but they are reproduced by asexual reproduction – known as fission (Fernandez, 2016). They are commonly in freshwater streams and ponds (Collines, 2007). They are carnivorous, feeding on living and

Once the experiment was concluded, aged water was slowly added to the temperature- stressed fish in order to raise the temperature of its water. This helped to return its environment back to normal conditions.

Questions to answer in your lab report. NOTE: some questions pertain to the week 1 exercise, some to week 2, and others to both. How is the amount of temperature variation related to the volume of the water body? How might you measure the speed of temperature change? How would you expect the speed of change to vary with habitat volume? Are water temperatures different than air temperatures? How are they different? Are there any cyclical patterns in the temperature-logged data (“time series”) from Angel? If so, what do you think caused these repeating patterns? Based on the results of this exercise, how might you

All across america, cows are confined to crowded, almost prison-like cells, with little to no regard to their health. They are forced to eat food that includes such ingredients like manure, cement, or even cow brains. This is one side of farming, but there is another. This farming has cows and other animals living how they would in nature, across rolling hills and bright green grasses. This is the essence of Local Sustainable farming. As defined in Michael Pollan’s award-winning commentary about the food we eat, The Omnivore’s Dilemma, the Local Sustainable Food Chain, one of four possible food chains, is characterized by not using pesticides, treating animals humanely, and sustainably creating healthier organic food. Out of Michael Pollan’s food chains, the Local Sustainable Food Chain is the best for America as it is much less harmful to the environment and lets animals live in their natural states.

Ectotherms experience many changes in their physiological and biochemical processes based on their surrounding temperature. Temperature can alter the way an ectotherm uses its energy in its daily activities. Researchers often measure this pattern of energy usage by looking at organismal metabolic rate. The metabolic rate can be described as all of the chemical processes occurring in a body. It is commonly determined by either the rate of production of CO2 or the rate of consumption of O2 (Nespolo et al. 2003).

The experiment goal was to measure the effects that different water temperatures had on the Daphnia's heart rate and the effects of epinephrine as well. Daphnia is commonly known as water flea bugs that are small aquatic crustaceans that is found plentifully in small bodies of fresh water (General Biology Study Guide and Lab Manual, 10th ed. 2007). These water bugs are good animals to use for this type of experiments because they are large enough to be seen without a microscope in light and under the microscope at twenty times magnification their internal organs can be seen straight through their body cavity. Daphnia are ectothermic creatures, meaning

When compared to a similar study, a similar conclusion was made. In a study conducted by Gerristen, he studied if Daphnia would experience a positive or a negative thermotactic reaction when exposed to a variety of different temperatures. Once the experiment was completed, Gerristen was able to conclude that the Daphnia did indeed experience a negative thermotactic reaction and swam away from the cold stimuli. He claimed that these results were due to the Daphnia’s natural instinct to seek warmer water (Gerristen 1982).

“Penguin responses to climate change in the Southern Ocean” by Jaume Forcada and Philip N. Trathan (2009) was a study conducted to analyze and predict the migrating patterns of different species of penguins due to changes in climate. (p. 1618) Also, Forcada and Trathan investigate whether or not certain species of penguins possess phenotypic plasticity (the ability of an organism to change its phenotype in response to changes in the environment) (p. 1618).

going to occur between 40°c to 60°c because this is the habitat temperature for these species and

The example given is the coral trout, a fish that is commercially important. Since the water temperature has risen higher up in the water, these trout tend to be more lethargic now; they stay lower in the water. This is crucial because all of their hunting and mating ground is higher
