How does energy and chemicals flow through an ecosystem?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
How can we compare nutrients and energy in an ecosystem?
Nutrients get recycled due to the cyclic movement of nutrients within the ecosystem. The energy flowing in an ecosystem will move in a single direction. In contrast, one-directional movement of mineral nutrients does not occur in an ecosystem due to their recycling back into the earth's atmosphere.
What is different about how energy moves through an ecosystem compared to how chemicals move through the ecosystem?
Energy and nutrients, or chemicals, flow through an ecosystem. While energy flows through the ecosystem and cannot be recycled, nutrients cycle within an ecosystem and are reused.
What is true about chemical nutrients in an ecosystem?
Answer and Explanation: The statement that is true about chemical nutrients in an ecosystem is B. they recycle within the ecosystem, being constantly reused.
Which is one way in which energy flow differs from chemical cycling?
Answer and Explanation: The way in which energy flow differs from chemical cycling is A) Energy flow is unidirectional; chemical elements can be recycled.
Do chemicals flow through an ecosystem?
Energy and nutrients or chemicals flow through an ecosystem. While energy flows through the ecosystem and cannot be recycled nutrients cycle within an ecosystem and are reused. Both energy flow and chemical cycling help define the structure and dynamics of the ecosystem.
What is the difference between energy flow and chemical cycling?
Key points. Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled. The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.
What is one way energy flow differs from chemical cycling quizlet?
What is one way in which energy flow differs from chemical cycling? Energy can enter but cannot leave an ecosystem; chemical elements can leave but cannot enter an ecosystem.
How is the movement of energy in an ecosystem different from chemical cycling quizlet?
What is an obvious difference between energy flow and chemical cycling? Energy flows through, and ultimately out, of ecosystems. Chemicals are recycled within ecosystems.
How does energy flow differ from chemical cycling?
Answer and Explanation: The way in which energy flow differs from chemical cycling is A) Energy flow is unidirectional; chemical elements can be recycled.
What is one way in which energy flow differs from chemical?
Answer and Explanation: The way in which energy flow differs from chemical cycling is A) Energy flow is unidirectional; chemical elements can be recycled.
How do nutrients and energy move through ecosystems quizlet?
Terms in this set (17) How does energy and nutrients flow/cycle through ecosystems? Organisms capture energy, and transform it to biomass and/or heat. energy is passed through "levels" in the ecosystem.
How does energy flow differ from chemical cycling quizlet?
What is one way in which energy flow differs from chemical cycling? Energy can enter but cannot leave an ecosystem; chemical elements can leave but cannot enter an ecosystem.
What is one way in which energy flows differs from chemical cycling quizlet?
What is one way in which energy flow differs from chemical cycling? Energy can enter but cannot leave an ecosystem; chemical elements can leave but cannot enter an ecosystem.
What is one way in which the movement of energy and chemicals differ in an ecosystem quizlet?
What is one way in which the movement of energy and chemicals differ in an ecosystem? Energy flow is unidirectional; chemical elements can be recycled.
How are the movements of energy and nutrients through living systems different?
Energy forms chemical compounds, and nutrients are lost as heat. So from above discussion we can conclude that correct answer is option B Nutrients recycle while energy flows in one direction. Note:- Energy flow refers to the flow of energy through food chains.
How is chemical cycling and energy flow different?
Key points. Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled. The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.
Why does energy flow in an ecosystem while chemicals cycle quizlet?
Why does energy flow, but chemicals cycle through an ecosystem? Energy flows from the sun to plants which then use photosynthesis to convert the solar energy to chemical energy. Other organisms then consume this energy by eating the plants. This energy does not cycle back to the sun.
Which statement best describes the movement of matter and energy in an ecosystem?
Which statement most accurately describes how matter and energy are used in ecosystems? 1. Matter flows through ecosystems; energy cycles within ecosystems.
What is one way in which energy flow differs from chemical cycle?
Answer and Explanation: The way in which energy flow differs from chemical cycling is A) Energy flow is unidirectional; chemical elements can be recycled.
How does the movement of energy through the biosphere compare with the movement of nutrients through the biosphere?
The movement of nutrients through the biosphere is different from the transfer of energy because, whereas energy flows through the biosphere and cannot be reused, elements are recycled.
Which of the following choices best describes a way in which energy and nutrients move through living systems?
So, the correct answer is 'Energy flows while matter is cycled'.
What is chemical cycling in an ecosystem?
Chemical cycling describes systems of repeated circulation of chemicals between other compounds, states and materials, and back to their original state, that occurs in space, and on many objects in space including the Earth. Active chemical cycling is known to occur in stars, many planets and natural satellites.
Which statement best describes the flow of energy and the movement of chemical compounds?
Which statement best describes the flow of energy and the movement of chemical compounds in an ecosystem? Energy is transferred from organisms in a food chain and chemical compounds are recycled.
How does energy flow differ from chemical cycling in an ecosystem?
The key difference between energy flow and matter cycling is that energy flow shows the energy transmission from one trophic level to next trophic level in food chains while matter cycling shows the flow or cycling of elements through the living and nonliving parts of ecosystems.
How is the movement of energy through living systems different than the movements of nutrients through living systems?
the movements of energy and nutrients through living systems are different because. energy flows in one direction, and nutrients recycle. direction, and energy recycles. energy forms chemical compounds, and nutrients are lost as heat.
Which statement best describes the flow of energy as it passes through the organisms in the pyramid?
Which statement best describes the flow of energy as it passes through the organisms in the pyramid? Energy flows through the organisms from bottom to top and increases at each level.
Which of the following is the correct representation of the flow of energy in an ecosystem?
Pyramids of energy Pyramids of energy are usually upright and are the best representation of energy flow and ecosystem structure.
What is one way in which energy flow differs from chemical cycling quizlet?
What is one way in which energy flow differs from chemical cycling? Energy can enter but cannot leave an ecosystem; chemical elements can leave but cannot enter an ecosystem.
Which statement best describes the flow of energy as it passes through the organisms in the pyramid quizlet?
Which statement best describes the flow of energy as it passes through the organisms in the pyramid? Energy flows through the organisms from bottom to top and decreases at each level.
