How does a selectively permeable membrane relate to diffusion and osmosis?

In 3–5 sentences, compare and contrast the flow of matter and energy in each trophic level for land-based ecosystems and marine

Mnenie [13.5K]

Answer:

Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.

Explanation:

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.

Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.

Which factor will not affect the strength of a solenoid

antoniya [11.8K]

Answer: A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside.

* Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.

* The magnetic field within a solenoid depends upon the current and density of turns.

* In order to estimate roughly the force with which a solenoid pulls on ferromagnetic rods placed near it, one can use the change in magnetic field energy as the rod is inserted into the solenoid. The force is roughly

change in magnetic field energy

force on rod = ---------------------------------------------------

distance rod moves into solenoid

* The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills. Iron has a much, much larger permeability than a vacuum.

* Even small solenoids can exert forces of a few newtons.

=> AFFECTS OF STRENGTH OF SOLENOID:

There are many factors and I cannot go fully into them here.

* Materials, size and duty of the solenoid all affect the operation. A solenoid, as you know, is a coil with an element which moves as a result of power being applied and removed. A simple switch.

* Clearly the more windings you have for set conditions of voltage will generate a greater field strength. The windings excite a core and the material of that core has a significant effect.

* The moving element can easily be made to suit power transfer requirement.

* So you need to understand application and work backwards. There may even be a solid state solenoid which can do the same thing.
