Matter flows through ecosystems; energy cycles within ecosystems.
Which statement best describes how matter and energy flow within an ecosystem?
In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.
Which of the following best describes movement of energy in an ecosystem?
Which of the following best describes the movement of energy in an ecosystem? Energy is harnessed by producers, and available energy decreases with each trophic level transfer.
What is the movement of energy in an ecosystem?
Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.
How does matter move between and within an ecosystem?
The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats.
How is the movement of matter and the movement of energy in ecosystems similar?
As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved.
Which statement below best describes the flow of matter and energy through trophic levels Group of answer choices?
Which statement below best describes the flow of matter and energy through trophic levels? Energy is transferred between organisms, and matter is released as heat.
Which of the following best describes why energy is lost at each trophic level?
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.
Which of the following best describes how the amount of energy changes as it flows from one trophic level to the next in the marine food web shown below?
Which of the following best describes how the amount of energy changes as it flows from one trophic level to the next in the marine food web shown above? … It becomes heat and unavailable chemical energy.
How do energy and matter move through an ecosystem quizlet?
How do energy and matter move through an ecosystem? Energy unidirectionally flows through an ecosystem, whereas matter generally cycles within an ecosystem.
Which statement about the movement of energy through ecosystems is true?
The correct answer is (c) energy flows in only one direction through an ecosystem.
How does matter and energy move among organisms in the food chain?
Matter cycles between the air and soil and among organisms as they live and die. … Food webs model how matter and energy are transferred among producers, consumers, and decomposers as the three groups interact within an ecosystem. Photosynthesis and cellular respiration provide most of the energy for life processes.
