There is no energy in an open system; there is matter. Which statement best explains why running on a track with constant speed at 3 m/s is not work, but climbing a mountain at 1 m/s is work? C. The price of gasoline increased. A) mammals, fish, insects. Energy flows stepwise through the community according to the second law of thermodynamics, but a given population ofa species may be (and very often is) involved in more than a single trophic level. B) at each step, energy is lost from the system because of the second law of thermodynamics. In autotrophs, the assimilated energy, A, is, of course, the gross primary production or gross photosynthesis. Some of the energy input may simply pass through the biological structure, such as when food is egested from the digestive tract without being metabolized or when light passes through vegetation without being fixed. D) Approximately 99% of the solar radiation is reflected. C) greater than the biomass of 2. Which statement best describes the energy in this system of chemical. Energy from the sun heats Earth's surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents. A) to replace a ruined ecosystem with a more suitable ecosystem for that area. E) It is recycled by decomposers to a form that is once again usable by primary producers.
A) the ratio of net secondary production to assimilation of primary production. What do you think would happen if you changed the amount of energy that was reflected by the atmosphere or Earth's surface? Standard notations for successive energy flows are as follows: La, light absorbed by plant cover; GPP gross primary production; A, total assimilation; NPP, net primary production; SP, secondary (consumer) production; NU, energy not consumed by next trophic level; E, energy not assimiliated by consumers (egested); I, input (or ingestion); B, standing crop biomass; and R, respiration. E. municipal waste incinerators. Students also viewed. Snc tst.docx - Which statement best describes how energy can change during a chemical reaction? The energy change for a chemical reaction can either be | Course Hero. B) Neither would change. Now that you have worked through the Earth's energy balance, discuss how changes in Earth's surface characteristics and / or atmospheric composition could contribute to global warming or cooling.
Work is when a force causes an object to move in the direction of that force; defined as force times change in distance. The ratio between A and I (the efficiency of assimilation) varies widely. E) producers, primary consumers, secondary consumers, top carnivores, and decomposers. A) to restore the physical structure. The Hubbard Brook watershed deforestation experiment yielded all of the following results except: - A) Most minerals were recycled within a forest ecosystem. D. Depletion of the ozone layer. The discipline that applies ecological principles to returning degraded ecosystems to a more natural state is known as. Which statement best describes the energy in this system? A.The potential energy in the system is - Brainly.com. Which of the following gives the work done by the force on the body as the displacement increases from zero to xQ and then returns to zero? D) It is eliminated as feces or is dissipated into space as heat in accordance with the second law of thermodynamics. In general, the proportion of energy going into respiration (maintenance energy) is large in populations functioning at higher trophic levels and in communities with a large standing crop biomass. This energy, which has been absorbed by the surface of the Earth, will now be transferred back to the atmosphere via several processes. D) compare nutrient concentrations between the photic zone and the benthic zone in various marine locations. B) gross primary productivity.
The work–energy theorem states that the change in the kinetic energy of an object is equal to what? An object of weight 50 N is dragged up an inclined plane at constant speed, through a vertical height of 12 m. The total work done is 1500 J. C) presence and absence of mycorrhizae. Get answers and explanations from our Expert Tutors, in as fast as 20 minutes. Production of greenhouse gases such as carbon dioxide. Which statement best describes the energy in this system of electricity. 15 g. What is the production efficiency of the grasshopper? D) energy that is not used by consumers for growth and reproduction. A disturbance that transfers energy. Use the diagrams and text below to guide your steps. 2 points) All energy and matter are contained within the system. D) use chemical energy to synthesize organic compounds.
Considering Joe and the ball together, which one of the following correctly describes the change in the magnitude of the. B) Satellite instruments can detect reflectance patterns of the photosynthetic organisms of different ecosystems. List three surfaces that reflect solar radiation. Trophic efficiency is. B) 50 g. - C) 20 g. Figure 42. Which statement best describes the energy in this system of equations. C. A cow's herbivorous diet indicates that it is a(n). The number of passengers per car increased. A large radius divided by a small radius is the expression used to calculate the IMA of what? These introductions continue through the transport of soil that contains non-native earthworms, such as during construction, and through the release of non-native earthworms used for fishing.
Why do logged tropical rain forests typically have nutrient-poor soils? The ratio work done by F2/ work done by F1 is. E) arresting nutrient cycling. A. power developed by the car.
