Briefly explain what the greenhouse effect is and how it affects all life on our planet. Additionally, what are two pieces of evidence introduced in class that demonstrate climate change is “real”?
Explain what happens with the total energy of the system at different trophic levels, indicating how much energy is transferred from one level to the next. Add a pesticide to your food chain and explain what happens with certain persistent chemical residues at different trophic levels.
1.
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.
it is the natural process that warms the Earth's surface. The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse
The following is a list of 10 steps YOU can take to reduce greenhouse gas emissions:
2.
The greenhouse effect is what keeps our planet warm enough to support life. Earth is said to be in a perfect "Goldilocks zone" away from the sun (not too cold, and not too hot), which enables life to thrive on the planet's surface
An expert in how climate change and biodiversity loss can affect human health, Bernstein, MPH '09, said that even a small global temperature increase could lead to troubling consequences, like rising sea levels, population displacement, disruption to the food supply, flooding, and an increase in infectious diseases
The evidence for rapid climate change is compelling:
Global Temperature Rise
Warming Oceans.
Shrinking Ice Sheets
3.
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
4.
Pesticides affect the food chain because they reduce the biomass of primary consumers. This means there is less food available to secondary consumers
5.
Bioaccumulation and bioconcentration result in buildup in the adipose tissue of successive trophic levels: zooplankton, small nekton, larger fish, etc. Anything which eats these fish also consumes the higher level of mercury the fish have accumulated.

Explain what happens with the total energy of the system at different trophic levels, indicating how much energy is transferred from one level to the next. Add a pesticide to your food chain and explain what happens with certain persistent chemical residues at different trophic levels.
Ecosystems How is food chain different from a food web? Explain the difference between gross primary production and net primary production? What is the role of plant metabolism (respiration) in productivity? Why is energy lost from a food chain? Where does it go? Is it destroyed'? What limits NPP? What patterns exist in NPP in oceans vs terrestrial ecosystems? Are nutrients involved with NPP? Which ones? What trophic level (group of organisms) is needed for every ecosystem? What do the...
NPP = GPP – R Net primary production = ______________ = GPP – energy used for cellular respiration Gross primary production = ________________ production of primary producers Respiration = ______________________ Thus NPP is the amount of energy available to primary consumers = primary production Explain the different ways in which primary production is influenced in terrestrial and aquatic ecosystems Primary production: terrestrial ecosystems influenced by water, temperature, and nutrient availability Evapotranspiration rate measures the amount of water entering the atmosphere...
Exercise 9- Evolution w a fossil's half-life is determined and why the oldest fossils are usua e main ideas concerning Darwin's life and his theory of evolution. 1. Know the lines of evidence that support evolution strata. 3. Know th 4 now what "descent with modification" is. 5. Review the bean: experiment. 6. Know how to read the "cytochrome c" chart. Which of the following give evidence that evolution has occurred? 1. a. morphological similarities b. embryological similarities c. fossils...
Define and provide examples of the following concepts: Environment, ecosystem, abiotic and biotic factors, natural and experimental boundaries, flows of matter and energy. Explain how the boundaries of an ecosystem may differ from those like national parks, county, state or national borders. Explain how natural features of the landscape (ex: a watershed) or biological phenomena (ex: a species range) can be used to define the boundaries of an ecosystem. Explain how ecosystems vary in size and scale, and how some...
1. Explain how bioavailability affects the functionality of vitamins within the body. Discuss how food preparation methods affect vitamin bioavailability. 2. Even though vitamins are not considered to be energy-yielding nutrients they play a required role in metabolism. How do they accomplish this task? Identify the significant roles of B complex vitamins in metabolism. 3. Describe a unique source of niacin and a unique function of niacin in the body. 4. Explain the features of folate that are associated with...

3. Griffiths draws a donut on page 448 (Fig 11.4). What is this drawing trying to demonstrate?! He doesn't label the figure, so take your own shot: how would you briefly and clearly explain to a reader what is being shown here? 471 11.1 Dipole Radiation FIGURE 11.4 mutually perpendicular, and transverse; the ratio of their amplitudes is Eo/ Bo c. All of which is precisely what we expect for electromagnetic waves in free space. (These are actually spherical waves,...
