A food chain describes the passage of energy between trophic levels. A food web is a set of interconnected and overlapping food chains. Food webs are interconnected, such as nearby land and a marine food webs.
What statement accurately describes the flow of energy through a food chain?
Energy flows from primary producers to consumers, in one direction only.
Which best demonstrates the flow of energy through the environment?
A food chain is a simple diagram that shows one way energy flows through an ecosystem.
Which statement best supports the description of energy in ecosystem?
Energy flows in a “one-way stream” through an ecosystem. Which statement best supports this description of energy in an ecosystem? Energy flows through a pyramid of energy and is not reused; it is lost as heat.
Which of the following is one way that energy flows in an ecosystem?
Energy flows through an ecosystem in a one-way stream, from primary producers to various consumers.
Which statement best describes the flow of energy as it passes through organisms in an energy 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 most accurately describes the flow of matter and energy within an ecosystem?
The matter and energy movements of virtually all ecosystems are more accurately described by food webs ([Figure 5]). … As ecosystems require a method to recycle material from dead organisms, grazing food webs have an associated detrital food web.
Which sequence shows the energy flow in an ecosystem?
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics.
What demonstrates the flow of energy and materials through ecosystems in a single pathway?
Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it. Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.
How energy moves through the 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 dependency of organisms in an ecosystem?
Which statement best describes the dependency of organisms in an ecosystem? The number of predators in an ecosystem determines the number of producers.
What best describes an ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Which statement describes how energy flows in the pyramid?
Which statement describes how energy flows in the pyramid? Energy is lost between each level.
