Answer:

EFFICIENCY

Explanation:

Efficiency of a machine is commonly defined as the ratio of output work (work done by the machine) to work done on the machine (input work) expressed as percent.

The efficiency of a machine offers insight on the level of energy preserved or giving out (lost) in a process.

If we examine a machine subjected to the level of work acted on it. Then the work acted on machine should be W.

The machine does its work as a result of the effort used on it to give the expected outcome. Then, the output formed by the machine should be W' .

Therefore,

The efficiency of the machine is evaluated as -

Efficiency

= work output (W)

--------------------------- × 100 

work input (W)

Explain why fertilizer use by farmers can have negative effects on aquatic ecosystems?
CaHeK987 [17]
The fertilizers used by farmers can have negative effects on aquatic ecosystems because there is every possibility that the runoffs from the fields can create an algal bloom in the nearby water body. This algal bloom can have a very negative effect on the living organisms of the aquatic body. I hope it helps.

3. What happens to the energy that is consumed by any level in an energy pyramid?​
beks73 [17]

Answer:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Compare and contrast the structure and function of a compound light microscope and a dissecting microscope. Be sure to discuss w
TiliK225 [7]
<span>Compound Microscope Compound microscope is commonly used in the schools and colleges. It comes under the category of microscopes used in biology. It has two lenses namely the objective lens and the ocular lens. It provides a magnification of 1500X. Eyepiece lens is of 10X or 15X power. It is used to observe bacterial, protozoa, various cells, etc.

</span><span>Dissecting Microscope It is also called stereo microscope. Its magnification power is less than the other microscope. It gives a 3 dimensional picture. Due to the low magnifying power they are used to observe little bigger objects than other microscopes. They are used in the surgeries, dissection, forensic science etc.</span>
