- Name the three main loopsof the hydrologic cycle. Then, describe how each of the three main loops operates to purify water in the biosphere. (Tell what happens in each loop that purifies the water.)Which is an unseen factor that affects the carrying capacity of the ocean? sunlight space water availability water chemistryFind the Flaw Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick. The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. The nitrogen cycle has four steps. Denitrification is where bacteria take nitrogen from the atmosphere and convert it into a form that is usable by other biological systems. Ammonification is where nitrogenous waste is converted into ammonia. Nitrification is where ammonia is converted into…

How much more energy should it take to provide you a meal of meat compared to vegetables?The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Evaluate the carbon cycle model. Predict the changes that would occur within the carbon cycle as a result of deforestation. Choose all that apply A) there would be less carbon in the soil due to the loss of trees B) there would be an increase in atmospheric carbon due to less plant respiration C) there would be an increase in atmospheric carbon due to decreasing photosynthesis D) there would be an increase in oceanic carbon due to increasing atmospheric levels E) there would be an increase in atmospheric carbon due to increased emissions from burning of treesLiving organisms play an important role in the recycling of many elements within an ecosystem.
