What best describes the flow of energy and the movement of chemical compounds in an ecosystem?
The flow of energy through an ecosystem is described as one-way or linear. This means that energy enters the ecosystem and passes through it without being recycled. Energy enters in the from of light (via photosynthesis) and leaves as heat. Heat is not used as a source of energy by living organisms. Chemical compounds can be recycled, so their movement is cyclical in an ecosystem. The same atoms are used over and over again, so your body will contain atoms that were in the bodies of dinosaurs, for example.
A cyclical disturbance in an ecosystem is an event that?
repeats over and over. Apex
How does energy enter the ecosystem?
used to convert low-energy carbon dioxide into high-energy carbohydrate, then passes through one or more of the organisms of the community, and is then lost to the ecosystem
Is the pressure gradient equal to gas flow over resistance?
no gas flow is equal to pressure gradient over resistance
Relationship between matter and energy in ocean ecosystem food chain?
· 1. Section 3 Matter and Energy in Ecosystems · 2. Energy Flow Through Ecosystems Food contains nutrients and energy needed for survival. Matter and Energy 3 When one organism is food for another organism, some of the energy in the first organism (the food) is transferred to the second organism (the eater). · 3. Energy Flow Through Ecosystems Producers are organisms that take in and use energy from the Sun or some other source to produce food. Consumers are organisms that take in energy when they feed on producers or other consumers. Matter and Energy 3 When organisms die, other organisms called decomposers take in energy as they break down the remains of organisms. · 4. Food Chains A food chain is a model, a simple way of showing how energy, in the form of food, passes from one organism to another. When drawing a food chain, arrows between organisms indicate the direction of energy transfer. Matter and Energy 3 · 5. Food Chains Food chains usually have only three or four links. This is because the available energy decreases from one link to the next link. In a food chain, the amount of energy left for the last link is only a small portion of the energy in the first link. Matter and Energy 3 · 6. Food Webs A food web is a series of overlapping food chains that exist in an ecosystem. A food web provides a more complete model of the way energy moves through an ecosystem. Matter and Energy 3 · 7. Food Webs Matter and Energy 3 · 8. Topic: Energy Transfer Food chains are models that represent energy moving through an environment. As food moves through a food chain very little energy is passed from one level to the next. Food webs are models of several overlapping food chains. · 9. Ecological Pyramids Most of the energy in the biosphere comes from the Sun. Producers take in and transform only a small part of the energy that reaches Earth's surface. Matter and Energy 3 · 10. Ecological Pyramids An ecological pyramid models the number of organisms at each level of a food chain. The bottom of an ecological pyramid represents the producers of an ecosystem. Matter and Energy 3 The rest of the levels represent successive consumers. · 11. Energy Pyramid An energy pyramid compares the energy available at each level of the food chain in an ecosystem. A pyramid of energy usually has three or four levels. Matter and Energy 3 Only about ten percent of the energy at each level of the pyramid is available to the next level. · 12. Topic: Energy Pyramids Most of the energy in an environment comes from the sun. An ecological pyramid models the number of organisms at each level of a food chain Only about ten percent of the energy at each level of the pyramid is available to the next level · 13. The Cycles of Matter The law of conservation of mass states that matter on Earth is never lost or gained. It is used over and over again. The carbon atoms in your body might have been on Earth since the planet formed billions of years ago. They have been recycled billions of times. Matter and Energy 3 · 14. Other Cycles in Nature Matter and Energy 3 The movement of carbon through Earth's biosphere is called the carbon cycle. · 15. Other Cycles in Nature The nitrogen cycle begins with the transfer of nitrogen from the atmosphere to producers then to consumers. Matter and Energy 3 The nitrogen then moves back to the atmosphere or directly into producers again. Phosphorus, sulfur, and other elements needed by living organisms also are used and returned to the environment. · 16. Topic: Matter and Cycles Matter cannot be created or destroyed. The three main cycles that affect living things are the water cycle, the carbon cycle, and the nitrogen cycle. Carbon is cycled through photosynthesis and respiration. (pg. 216, 275) Nitrogen is mainly cycled from producers to consumers and back to the atmosphere. (pg. 216) · 17. What Have You Learned? Why will most habitats never reach biotic potential? What is the difference in food chains and food webs? What does an energy pyramid show? What cycles mainly effect living things?
What is the over all flow of energy through an ecosystem?
Energy in an ecosystem flows in whats called the 10% rule. Meaning, as you move up the pyramid 10% of energy is lost.

Does the food chain transfer nutrients from organism to organism?
Yes. Food or fuel creates energy, energy is transferred through "nutritional" content. There are several different factors that control the primary productivity of energy and biomass flow. Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow. In the study of energy flow, ecologists try to quantify the importance of different species and feeding relationships. The largest source of energy for an ecosystem is the sun.Energy that is not used in an ecosystem is eventually lost as heat. 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.
Why does the flow of matter in an ecosystem stay constant over time?
because the decomposers spend back the energy to the producers
How is food web related to energy flow within an ecosystem?
i am only a 5th grader and we just went over that and when a organisum eats a organisum then it gets energy from eating it
How energy flow through the ecosystem food web?
Energy flows up a food chain, from the primary producers to the primary consumers, to the secondary consumers, up to the tertiary and then quaternary consumers. Energy flows when one organism eats another.
The flow of energy in an ecosystem can be illustrated by a pyramid Why is less energy available at the top of the pyramid than at the bottom of the pyramid?
This is a confusing shape to use as an illustration. To the average person, the large base of the pyramid represents much energy stored compared to the diminishing storage space as you look higher and higher up the pyramid towards its peak. However, those that have studied the actual flow of pyramid energy have seen an upward movement of energy through the peak into the air above. So it's not necessarily true that more energy is flowing at or near the base than at the top. A mysterious flow of energy skyward which disrupts instrumentation on aircraft has caused the Egyptian authorities to forbid flying over the top of the pyramids at Gisa, for safety reasons.
What are the levels of ecological hierarchy?
A graphical representation in the shape of a pyramid to show the feeding relationship of groups of organisms, and the flow of energy or biomass through the different trophic levels in a given ecosystem.

Is rainfall in the coral reef ecosystem?
yes it is.it is an abiotic factor because it will over flow the sea and then fish will die cuse they are out of water.
Over time a group of species in an ecosystem is replaced by a different group of species through?
Succession
Does energy leave the ecosystem in the form of heat?
If by the 'ecosystem' you mean the surface of the earth and its atmosphere, which includes all living things on earth, then yes, the only way for energy to leave is by radiation out into space. The ecosystem receives heat from the sun and from the earth's hot interior, and radiates heat back into space, thus maintaining a thermal balance over time.
Why are cheetahs valuable to our ecosystem?
It is valuable because they keep our ecosystem balanced by killing prey and not letting them over populate.If there was no cheetahs they will over populate and the ecosystem will be unbalanced
