The correct answer is 3. A food web shows how energy is transferred in an ecosystem. … The chemical energy stored in producers are transferred to the consumers once they eat the plants.
Which statement accurately describes how matter and energy are used in ecosystems?
The correct answer is (c) energy flows in only one direction through an ecosystem.
What is the flow of matter and energy in 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.
What is the most accurate way to show energy and matter flow through an ecosystem?
Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.
Which statement below best describes the flow of matter and energy through trophic levels?
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 model best illustrates the flow of energy and matter in an ecosystem a food chain or food web?
Which model best illustrates the flow of energy and matter in an ecosystem a food chain or a food web? It is made up of interconnected food chains. It is more complex and much larger than a food chain since it shows the feeding relationships of many producers and consumers at each trophic level.
How does matter move within and between ecosystems?
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 do matter and energy flow inside and outside the Earth?
Energy flows around Earth from many sources and in many forms. … In the rock cycle, rocks and matter go through uplift, weathering, erosion, deposition, melting, crystallization, and metamorphism as they travel between Earth’s surface and its interior layers.
How does energy flow in an ecosystem quizlet?
How does energy flow through ecosystems? Energy flows through an ecosystem in a 1-way stream, from primary producers to various consumers. … Producers receive chemicals from light rays, 1st-level consumers eat producers, 2nd-level consumers eat 1st-level consumers, and 3rd-level consumers eat 2nd-level consumers.
What is the most accurate model of an ecosystem?
Analytical models use mathematical equations to predict and describe simple, linear components of ecosystems, such as food chains. Simulation models use computer algorithms to predict ecosystem dynamics; they are considered the most ecologically-realistic and accurate.
How does the flow of matter differ from the flow of energy?
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.
What model shows the most realistic flow of energy between organisms?
– A food chain is most realistic because many organisms eat a variety of foods, and energy moves through different pathways. – A food web is most realistic because many organisms eat one type of food, and energy moves through a single pathway.
Which of the following best describes how the flow of matter through an ecosystem differs from the flow of energy?
Which of the following best describes how the flow of matter through an ecosystem differs from the flow of energy? Energy flows one way through ecosystems, and matter is recycled within ecosystems.
Which statement best explains the flow of energy as it moves through the different levels?
Which statement best explains the flow of energy as it moves through the different levels? Energy is unavailable because it is used up by the organisms at Level 1.
Which statement best explains why a food web more completely represents the flow of energy through an ecosystem than a food chain does?
Which statement best explains why a food web more completely represents the flow of energy through an ecosystem than a food chain does? Relationships between organisms usually change quickly enough to make food chains inaccurate.
