C producers, primary consumers, and decomposers. B The phosphorus cycle is a sedimentary cycle that involves the weathering of rocks. Let's use the old conservation laws 1. At Wog Wog, there was high mortality of old trees at the edges of fragments because, when the landscape was fragmented, the edges of fragments experienced more wind, and more trees were knocked over. Show transcribed image text Analyzing energy flow Which of the following statements about energy flow are true? This led to less competition between old trees and young trees for light and water at the edges of fragments, and, as a result, more young trees sprouted and grew.
C About 90% of the energy at one trophic level does not appear at the next. B Energy is cycled through ecosystems; matter is not. Which of the following statements is true? D Collect the clippings and wash them into the nearest storm sewer that feeds into the local lake. Energy contained in feces is available to higher trophic levels. Which of the following statements are true about an electric potential or electric potential difference? C Autotrophs typically capture about 90% of the available energy from the sun through photosynthesis. Heat flows from the water to the ice, cooling the water and melting the ice.
Assuming the water in the glass is initially at the same temperature as the flowing water, the flowing water will melt the ice faster. Solids have definite shape and volume, and their particles are in a fixed in a position, but they still vibrate. D usually greater than production efficiencies. Charge is not created; charge is not destroyed; and charge does not accumulate at a location in a circuit. A decline in the exotic species of corals and turtles and other forms of marine life in the affected waters. E producers, primary consumers, secondary consumers, top carnivores, and decomposers.
If it were connected to a 6-Volt battery instead, its resistance would increase by a factor of 4. Plants, algae, and cyanobacteria are primary producers upon which entire ecosystems are dependent. The current in the circuit is 1 Amp. It's a perfect resource for those wishing to improve their problem-solving skills. A Mortality and birth rates should be similar on islands with and without population declines B The number of sea otters disappearing from certain islands should lead to an increase in the number of otters on other islands C The islands with declining population sizes have reached their carrying capacity D All of the above would actually be consistent with the different dispersal rates hypothesis Which of the following statements about age pyramids is true? Energy contained in feces is available to higher trophic levels.
B the percentage of production transferred from one trophic level to the next. The molar heat of melting is 6. If you were to place your battery on top of your hood, it would still be the internal circuit. Photosynthesis and cellular respiration are performed by plants. Ние от Oath и нашите партньори се нуждаем от Вашето съгласие за достъп до Вашето устройство и използване на Вашите данни, включително местоположението Ви , за да разберем Вашите интереси и да предоставяме и измерваме ефективността на персонализираните за Вас реклами. B Through measurements and observations, we know that carbon dioxide and temperature were correlated even in prehistoric times.
B Populations in developed countries grow more quickly than populations in less-developed countries. Most solar energy is used in photosynthesis. B Some gypsy moths cannot feed and thus die because others moths have defoliated the trees in the area. Work is done on the charge as it passes through the battery, thus pumping the charge up to a high energy. I don't think I could do it directly, and I would probably be using the the kinetic molecular theory to design some experiment to measure them indirectly. Thus, it must drop 12 Volts during the pass through that resistor. The internal circuit supplies electrical energy to the charge and the electrical energy is converted to other forms of energy in the external circuit.
It must pass through both resistors in consecutive fashion before returning to the - terminal of the battery. Energy contained in feces is available to higher trophic levels. The electric potential difference across each resistor is 12 Volts. Which statements about the scenario are true? This is based on the convention that the direction of the electric field is the direction that a + test charge would be accelerated. And the charge subsequently does work upon the elements of the external circuit, transforming its electric potential energy to other useful forms light, sound, mechanical, thermal, etc. Whether the battery is inside the hood or not has nothing to do with it.
A A male robin attacks a red tennis ball because it confuses it with an encroaching male who will steal his territory. We do lose energy, so this is a bad choice. D B and C only E A, B, and C How does inefficient transfer of energy among trophic levels influence the typically high risk of extinction shared by most top predators? The information provided on this site is protected by U. Which of the following statement about energy and nutrients in an ecosystem is true? The amount of carbon that is processed during photosynthesis is referred to as gross primary production. One focus of the Wog Wog project is to understand how reducing habitat size impacts extinction rates of different beetle species.
