Textbook Question
Chapter 17, Problem 2GFO
How many biomes do you rely on to supply your food? Many grocery stores label the origin of their produce. The next time you go to the grocery store, try to determine the number of different countries from which your groceries come. Could you easily change your diet and shopping habits to rely on locally produced food? Why or why not?

Students have asked these similar questions
Which is/are the abiotic components of an ecosystem?
1.Soil
2.Protein
3.Carbon
4.All of the above
1. Which organism have the most supply of energy?
2. Which has the least amount of energy?
3. Why is there a decrease of the amount of energy as we go up the food pyramid?
4. Where did the energy go due to losses?
5. Which among the organism in example 2 (food web) receives the least amount of energy? (except decomposers).
On a piece of paper draw the nitrogen and the carbon cycle for a terrestrial ecosystem. The cycles should show the detail of the transformation of the element, where the transformation occurs, as well as biotic and abiotic components.
Now, starting with the animal, write out your description of the nitrogen cycle then describe the carbon cycle.

- Four common relationships between organisms are listed in the box. 1. Bees pollinate plants as they move from flower to flower gathering nectar. 2. Green algae grow on the backs of spider crabs living in shallow water, camouflaging the spider crabs while the crabs protect the algae from predators. 3. Fleas live on the skin of dogs and obtain nutrients from the dogs' blood. 4. Nitrogen-fixing bacteria obtain nutrients from their host plants and use the nutrients to supply nitrogen to the plants. Which statements best describe these relationships? O Relationships 1 and 4 are examples of mutualism. Relationship 2 is an example of con sm. Relationship 3 is example of parasitism. nensa O Relationships 1 and 2 are examples of commensalism. Relationships 3 and 4 are examples of mutualism. Relationship 1 is an example of commensalism.

Using a curtain that does not allow water, nutrients, or organisms to pass through, you divide your pond into four equal-sized quadrats (like a pie with four pieces). You randomly apply one of the following treatments to each quadrat: no nutrients (control), nitrogen only, phosphorus only, nitrogen and phosphorus. After 10 days, you measure net primary productivity (NPP) in each quadrat of your pond. You find the following results: Control NPP = 1.2 g C/m2/d; nitrogen only NPP = 1.3 g C/m2/d; phosphorus only NPP = 2.8 g C/m2/d; nitrogen and phosphorus added NPP = 2.8 g C/m2/d. Which is true about nutrient limitation in your pond? Nitrogen and phosphorus are both limiting nutrients Nitrogen is the only limiting nutrient Neither nutrient is limiting Phosphorus is the only limiting nutrientarrow_forwardPlant growth is limited by available nitrogen. Why is nitrogen fixation a limiting factor? There is very little nitrogen available after fossil fuel combustion utilizes the available nitrogen. Nitrogen must be produced by bacteria due to the inability of recycling by decomposers. There is no nitrogen in the atmosphere; it is only found in aquatic biomes. The stability of nitrogen gas makes it difficult to turn into nitrogen for living things.arrow_forward
- Chapter 10 of your textbook describes four biogeochemical cycles (some of which might also be called nutrient cycles) which carry elements and compounds essential to life on earth: the oxygen cycle, the carbon cycle, the nitrogen cycle and the phosphorous cycle. Read the sections in the textbook and refer to the diagrams for each of the cycles.These cycles are constantly going on around us. Think about how we are involved in these cycles. What parts of the major biogeochemical cycles do we witness or experience in our daily lives? Give one example per post or response. Think about where the element or nutrient may have come from or where it may go next and whether the process may have been affected by humans and human activities.A simple example (using the hydrologic cycle, which we studied in Chapter 7): Yesterday I was at the beach and witnessed rain falling into the ocean. This is part of the hydrologic cycle. Most of the rainwater probably came from evaporation of water from the…arrow_forwardDescribe a nitrogen cycle that could take place in the picture above. Describe how nitrogen could move from an abiotic element of the system to a biotic element and back.arrow_forwardWhich of the following statement about CBOD and NBOD is wrong? O CBOD is carbonaceous biological oxygen demand. This BOD refers to the portion of total BOD usually related to organic carbons as result of biodegradation. O NBOD is non-biological oxygen demand. NBOD refers to the portion of total BOD usually related to the conversion of ammonia nitrogen to nitrite or nitrate. O CBOD and NBOD evolve at different stages of biodegradation. O NBOD is characterized by a post stage of biodegradation, where CBOD occurs throughout the entire biodegradation if any carbonaceous organics are present.arrow_forward

- Increasing levels of carbon in the atmosphere have been linked to changes in the global climate patterns. You will be asked about this in the next questions. We also talked about more direct impacts of higher atmospheric carbon levels on living systems (I included them in the Nutrients - Bioshpere lecture). Describe one non-global climate change (something that does not involve a change in temperatures or rainfall) impact on the ecology of living systems and how increasing carbon levels in the atmosphere cause this impact.arrow_forwardUse the information show below to draw a food web.
