Which of the following is not true concerning the flow of energy through an ecosystem?
The statement which is not true concerning the flow of energy through an ecosystem is that most solar energy is used in photosynthesis.
Which of the following best describes the fate of energy in ecosystems quizlet?
Which of the following best describes the fate of energy in ecosystems? It flows through and is used by ecosystems. Which of the following is the balanced chemical equation for photosynthesis?
Is it true that every time energy is transferred between organisms in a food web some of the energy is lost as heat?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
Is most of the energy that enters ecosystems in the form of sunlight?
3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
Which of the following levels is the most efficient at energy conversion?
The correct answer is A) producers.
Which statement is true concerning the movement of energy through ecosystems?
The correct answer is (c) energy flows in only one direction through an ecosystem.
What is true about the efficiency of energy transfer in an ecosystem?
Which of the following is true about the efficiency of energy transfer in an ecosystem? The less energy the organism requires, the more efficient the energy transfer. … Since energy is also lost every time energy is transferred between organisms, that lost heat must go somewhere.
Which if the following best describes the fate of energy in ecosystems?
The Earth’s surface is responsible for a small fraction of heat radiation to space. d. Earth’s surface absorbs little of the energy that strikes as solar radiation. Which of the following best describes the fate of energy in ecosystems?
What provides the most energy in an ecosystem?
In most ecosystems, the ultimate source of all energy is the sun.
Why is the transfer of energy in a food chain usually only about 10 percent efficient?
The energy transfer is only ten percent efficient because much of the energy is used up on life processes, such as respiration, growth, movement, and reproduction.
How energy is transferred within and between organisms?
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. … This energy can then be passed from one organism to another in the food chain.
