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.

What term describes the movement of the radius around the ulna?
The term that describes the movement of the radius around the ulna is called pronation (inward rotation) and supination (outward rotation).
A step in the movement of energy through an ecosystem is called a?
A step in the movement of energy through an ecosystem is called a trophic level. This refers to the position an organism occupies in a food chain or food web, based on its feeding patterns and energy source.
How do chemicals move through an ecosystem?
Chemical nutrients can move through an ecosystem through plants. The plants can extract chemical nutrients from the ground and when animals eat green plants, they transfer from plants to animals.
Which is a better model of the movement of energy through an ecosystem a food chain or food web explain why?
A food web is a better model of the movement of energy through an ecosystem than a food chain because it shows the complex interactions and interconnectedness of different species within an ecosystem. Food webs illustrate the multiple paths through which energy flows, capturing a more realistic representation of the ecosystem compared to a linear food chain. Additionally, food webs account for the presence of omnivores, decomposers, and other ecological relationships that are not captured in a simple food chain.
The compounds in biological membranes that form a barrier to the movement of hydrophilic materials across the membranes are?
phospholipids and cholesterol are the main compounds that form the barrier to the movement of hydrophilic materials across biological membranes. The hydrophobic tails of the phospholipids create a barrier that prevents the passage of hydrophilic substances. Cholesterol helps maintain the fluidity and stability of the membrane.
How are the movement of energy and the movement of chemicals in ecosystem different?
Energy is not recycled, it flows in and out in a unidirection. Chemical energy enters as light energy and is produced by producers and leaves the ecosystem as heat.
Which phrase best describes a biochemical cycle?
the movement of a chemical substance through both the biotic and abiotic parts of earth
Is wind chemical energy?
No, wind is not chemical energy. Wind is a form of kinetic energy produced by the movement of air molecules in the atmosphere. Chemical energy, on the other hand, is stored in the bonds of chemical compounds and is released during chemical reactions.
What term describes the movement of continents?
The term that best describes the movement is gradual.
What term best describes the movement of continents?
The term that best describes the movement is gradual.
What is the typical movement of energy through an ecosystem?
Energy enters an ecosystem through sunlight and is converted into chemical energy by producers through photosynthesis. This energy is then transferred to consumers through the food chain as they eat other organisms. Ultimately, energy is lost as heat as it moves through the ecosystem.
Atoms and molecules are in constant?
Pretty much everything bigger than an atom.
Is the rock cycle a biogeochemical cycle?
No, the rock cycle is not a biogeochemical cycle. The rock cycle describes the processes through which rocks are formed, weathered, and transformed over time due to geological forces, while biogeochemical cycles involve the movement of elements and compounds through biological, geological, and chemical processes in ecosystems.
In the absence of humans are the bio geochemical cycles stable?
Bigeochemical is the movement of a particular chemical through the living parts of an ecosystem. Humans may change state as they move through their cycles.
What are the dynamics of any ecosystem?
two major process 1 = cycling of nutrient 2= chemical energy (food)
What best describes the movement of the Gulf Stream?
what describes the flow of water in the gulf stream
What are the 3 natural cycles?
The three natural cycles are the water cycle, carbon cycle, and nitrogen cycle. The water cycle describes the movement of water through evaporation, condensation, and precipitation. The carbon cycle involves the transfer of carbon among the atmosphere, oceans, soil, and living organisms, playing a crucial role in regulating Earth's climate. The nitrogen cycle describes the conversion of nitrogen between its various chemical forms, which is essential for plant growth and ecosystem health.
