There is heavy rainfall, and most of the year it is very cloudy.It is located near two fast-flowing rivers. The people want to build a power plant that will not pollute.They are choosing between solar, biomass, or hydroelectric power. Write one to two sentences about each of these energy sources.

Include drilling, transport, and usearrow_forwardWhich statement about energy is false?Group of answer choices It includes work, plus anything that can be transformed into work. In chemical form, it is passed up the food chain, along with nutrients. It moves between the living and nonliving world. Because energy is neither created nor destroyed, ecosystems can run indefinitely without any input energy. Some ecosystems can function independent of the energy of sunlight.arrow_forwardDecomposers cannot obtain their energy directly by photosynthesis. True Falsearrow_forward
- An organism that benefits from the outside production of a compound that inhibits the competition without depleting its own energy is described as a _________arrow_forwardCarbon dioxide in the atmosphere traps heat. Scientists are concerned that too much carbon dioxide is being released into the air by human activity. Using your knowledge of the carbon cycle, where do you think this carbon dioxide is coming from? List at least three possible sources of human-related carbon dioxide production. Carbon dioxide is produced by the burning of fossil fuels.arrow_forwardAs the sun shines on Earth, plants use its energy to complete the process of photosynthesis. Energy is transformed during the process into chemical energy in the form of sugars, such as carbohydrates. However, the energy available at top consumers is much less than that produced by autotrophs. Why is this so?arrow_forward
