You're right on the first part! Matter and energy are indeed cycled through living and non-living systems on Earth. This continuous flow sustains life and shapes our planet.
As for energy, it travels through a one-way street in this cycle. Unlike matter, which can be recycled and reused, energy gets transformed as it moves through the chain. Here's the breakdown:
Sun as the Source: The sun is the primary energy source for Earth. It emits solar energy, which is a form of radiant energy.
Capturing Solar Energy: Living things, like plants, capture this solar energy through photosynthesis. During this process, the energy is transformed into chemical energy stored in the bonds of organic molecules (e.g., glucose).
Transferring Energy: When herbivores eat plants, they consume the stored chemical energy. Carnivores, in turn, get their energy by consuming herbivores. This transfer of energy happens along the food chain.
Cellular Respiration: Both plants and animals use cellular respiration to break down these organic molecules and release the stored chemical energy for their cellular functions. However, some usable energy is inevitably lost as heat during this process.
Heat Dissipation: Ultimately, all the energy not used for biological processes escapes as heat and radiates back into space. This heat loss is why energy cannot be recycled in the same way matter is.
So, while matter cycles and gets reused, energy gets transformed and ultimately dissipates as heat.
True, both matter and energy are cycled through the living and non-living systems on earth. Explanation: In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed. In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed. Energy and matter are often cycled within a system, and different forms of matter and energy are able to interact. Matter is cycled through the ecosystem in biogeochemical cycles. However, energy is not recycled, but it flows in the ecosystem. Energy is responsible for making the biogeochemical cycles run continuously in our ecosystem. Matter cycles within ecosystems and can be traced from organism to organism. Plants use energy from the Sun to change air and water into matter needed for growth. Animals and decomposers consume matter for their life functions, continuing the cycling of matter. nergy 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 measures the amount of energy that is transferred between trophic levels. At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat. As we move from step to step in a chain or web, energy is lost as heat at each level. This is because organisms use energy for their own metabolism and only a portion of the energy is passed on to the next level. The amount of energy transferred from a lower trophic level to a higher trophic level always decreases as energy is lost at each step as heat. Only 10 percent of energy is transferred from one trophic level to the next. Both matter and energy are cycled through the living and non living systems on Earth is Energy flows while matter is cycled: True. Explanation: Energy is passed from one trophic level to the next trophic level. Hence energy flows through successive trophic levels in a food chain. Matter cycles within ecosystems and can be traced from organism to organism. Plants use energy from the Sun to change air and water into matter needed for growth. Animals and decomposers consume matter for their life functions, continuing the cycling of matter.
Yes, both matter and energy are cycled through living and non-living systems on Earth, but they follow different pathways and undergo different transformations.
Matter Cycling: Matter, such as carbon, nitrogen, phosphorus, and other elements, cycles through living and non-living systems on Earth. This cycling involves processes like photosynthesis, respiration, decomposition, and nutrient uptake by organisms. Matter is continuously recycled and reused within ecosystems, moving between biotic (living) and abiotic (non-living) components such as soil, water, and the atmosphere. For example, carbon dioxide is taken up by plants during photosynthesis, incorporated into organic compounds, and then released back into the atmosphere through respiration or decomposition.
Energy Flow: Energy, on the other hand, flows through ecosystems in a unidirectional manner, starting from the sun and ultimately dissipating as heat. Energy enters ecosystems as sunlight, which is captured by autotrophic organisms (such as plants) and converted into chemical energy through photosynthesis. This chemical energy is then transferred through the food web as organisms consume one another. However, with each transfer of energy, some energy is lost as heat due to metabolic processes, and this heat is ultimately dissipated into the environment. Therefore, energy flow through ecosystems follows a linear pathway, with energy being continuously inputted from the sun and gradually lost as heat.
As energy moves through the steps in a food chain or food web, it undergoes several transformations:
Photosynthesis: During photosynthesis, solar energy is converted into chemical energy stored in the bonds of organic molecules (such as glucose) by autotrophic organisms.
Consumption: When herbivores consume plants or carnivores consume herbivores, they obtain chemical energy stored in the organic molecules of their prey.
Respiration: Organisms release energy stored in organic molecules through cellular respiration to fuel their metabolic processes. This process converts chemical energy into forms that can be used for cellular work, such as ATP (adenosine triphosphate).
Heat Production: With each step in the food chain, some energy is lost as heat due to inefficiencies in energy transfer and metabolic processes. This heat is released into the environment and cannot be reused by organisms for metabolic work.
Overall, energy is continuously flowing through ecosystems, sustaining life processes and driving ecological interactions, while matter is recycled and reused within ecosystems, moving between living and non-living components.
In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed. Energy and matter are often cycled within a system, and different forms of matter and energy are able to interact. Matter and energy are indeed cycled through living and non-living systems on Earth. This continuous flow sustains life and shapes our planet. As for energy, it travels through a one-way street in this cycle. Unlike matter, which can be recycled and reused, energy gets transformed as it moves through the chain. Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. Matter is cycled through the ecosystem in biogeochemical cycles. However, energy is not recycled, but it flows in the ecosystem. Energy is responsible for making the biogeochemical cycles run continuously in our ecosystem. 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. As we move from step to step in a chain or web, energy is lost as heat at each level. This is because organisms use energy for their own metabolism and only a portion of the energy is passed on to the next level. The first trophic level consists of producers called autotrophs.
