Which statement most accurately describes how matter and energy are used in ecosystems? Energy flows through ecosystems; matter cycles within and through ecosystems. The law of conservation of matter states that matter cannot be created, yet matter is sometimes gained or lost to an ecosystem.
How do nutrients and energy move through ecosystems quizlet?
How does energy and nutrients flow/cycle through ecosystems? Organisms capture energy, and transform it to biomass and/or heat. … Ultimately, all is lost as heat, along the way, it may reside in energy rich compounds. Primary producers make biological tissues using inorganic molecules (own food).
What is the main difference between the flow of energy and nutrients in an ecosystem quizlet?
How does the way that matter flows through an ecosystem differ from the way that energy flows? Energy flows one way, matter is recycled within and between ecosystems. Why do living organisms need nutrients? To build tissues and carry out life functions.
Which statement best describes the flow of energy and matter through the terrestrial ecosystem?
Which of the following best describes the flow of energy in most terrestrial and near-surface marine ecosystems? Producers use energy from the sun to make organic matter, such as sugars, from carbon dioxide and water and are then consumed by organisms higher in the food chain.
What percentage of visible light striking a plant is converted into chemical energy?
Of the visible light that reaches photosynthetic organisms, only about 1% is converted to chemical energy.
How do nutrients and energy move through the ecosystem?
The energy and mineral nutrients move from the green plants i.e., producers to the consumers. It is mediated by the foodchain and food web. The light energy is trapped by the green plants fron the process of photosynthesis. … The mineral nutrients are absorbed by the plants from their root hairs.
How is energy and nutrients transferred in an ecosystem?
Energy and nutrients are passed around through the food chain, when one organism eats another organism. Any energy remaining in a dead organism is consumed by decomposers. Nutrients can be cycled through an ecosystem but energy is simply lost over time.
What is the difference between energy and nutrients?
Foods that are energy dense have lots of calories per serving. The calories may come from protein, fat, or carbohydrates. Foods that are nutrient dense have high levels of nutrients per serving. Nutrient dense refers to the amount of vitamins, minerals, and/or protein in a food.
What is the main difference between the flow of energy and nutrients in an ecosystem?
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem, but the main difference is that the nutrient cycle is recycled in the ecosystem while the energy flow is ultimately lost from the ecosystem to the universe at large. In the ecosystem, energy comes from the sun.
How do the flow of energy and matter differ from one another?
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.
Which statement best describes energy transfer in a food web quizlet?
The correct answer is 3. A food web shows how energy is transferred in an ecosystem. For instance, the solar energy is transferred to the producers such as plants so that they can convert it into chemical energy. The chemical energy stored in producers are transferred to the consumers once they eat the plants.
Which statement correctly describes the flow of energy in this energy pyramid?
Which statement correctly describes the flow of energy through this pyramid? Energy is directly transferred from the primary consumers to the secondary consumers.
Which statement best describes the distribution of energy in this food web?
Which of the following correctly describes the distribution of available energy among the different trophic levels of any food web? The amount of available energy is the highest among the primary and tertiary consumers of the food web.
