Question: Which statement best explains how energy is passed in an ecosystem?

Which statement best describes how matter and energy flow within an ecosystem?

Which statement BEST describes how matter moves within and between ecosystems? Matter flows in a one-way direction through food chains and food webs. Matter cycles between trophic levels in food chains and food webs.

Which law best explains how energy is transferred through the ecosystem?

Energy transfers within food webs are governed by the first and second laws of thermodynamics. … The second law explains why energy transfers are never 100% efficient. In fact, ecological efficiency, which is the amount of energy transferred from one trophic level to the next, ranges from 5-30%.

Which one of the following best represents the flow of energy in an ecosystem?

A food chain is a simple diagram that shows one way energy flows through an ecosystem.

Which of the following trophic levels represents a primary producer in an aquatic food chain?

Which of the following trophic levels represents a primary producer in an aquatic food chain? Phytoplankton uses solar energy to produce food; it is a producer.

Which statement describes the flow of matter and energy in decomposers?

3)A decomposer breaks down decaying matter to produce energy and release nutrients back into the environment.

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.

How is energy transferred in 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.

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.

How does energy move through an ecosystem?

Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. … Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.

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.

Which statement best describes the flow of energy in this pyramid?

Q. 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 best describes the flow of energy in most terrestrial and?

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.
