About how much energy is transferred between a producer and primary consumer?

Physics

Elza [17]3 years ago
3 0

Answer

Correct Answer is C (10% of the plant's energy is transferred

Explanation:

Ecosystem

ecosystem is a community where large number of  living organisms lives. These living organism are plants, trees, different types of animals, birds etc. These living organism depends on each other for their food.

Their are various levels in ecosystem like producer, primary consumer, secondary consumer and tertiary consumer.

producer like plants produce their food on their own. And primary consumers takes their food from producers.

According to 10% Rule of ecology only 10% energy is passed from one level to another.So 10% of the plant's energy is transferred

DENIUS [597]

Answer:

28.3 m/s

Explanation:

Vi = 45 Km/h = 12.5 m/s

Vf - Vi = at

Vf -12.5 = 0.45(35)

Vf= 28.3 m/s

Describe the wavelength of a longitudinal wave.
Lilit [14]
In Longitudinal waves, particles of the medium vibrate around their mean positions. Their amplitude of vibration is in the direction of the propagation of the wave. In transverse wave of longitudinal wave, <em>the wavelength is always the distance between two particles which are in the same phase.</em>

If we take pressure waves, (sound waves), we have pressure variations created by sound wave along its path. Pressure is maximum at compression regions and pressure is minimum at rarefaction region. In between the two, pressure of air remains as the pressure when there is no wave.

<em>The wave length is then the distance between two consecutive rarefactions or two consecutive compression regions.</em>

<em>It is also the distance traveled by the wave in one time period.</em> Time period is the time the particles in the medium take to vibrate towards the end, turn back to reach the other end of their oscillation and then reach back their position.

Cells are visualized using light microscopes and electron microscopes. Which statement about microscopes is false. Group of answ
denpristay [2]

Answer:

Light microscopes use light and glass objectives to illuminate and magnify objects

Explanation:

Light microscopes and electron microscopes are used to study cells. The electron microscope has many times more resolving power than the ordinary light microscope. A light microscope contains an objective lens and an eyepiece through which the final image is seen.

Both light and electron microscopes magnifies the image of the object. The magnifying power of an electron microscope is many times that of the light microscope.

Unpolarized light passes through a combination of two ideal polarizers. The transmission axes of the first polarizer and the sec
Yuliya22 [10]

Answer:

62.5 %

Explanation:

Let the initial intensity of unpolarized light is Io.

After first polariser the intensity of light becomes I'.

So, I' = \frac{I_{0}}{2}

Now it passes through another polariser. The angle between the first polariser and the second polariser is given by Ф. The intensity is I''.

According to the law of Malus

I'' = I' Cos^{2}\phi

Here, Ф = 30 degree

I'' = \frac{I_{0}}{2} Cos^{2}30=0.375I_{0}

The percentage change in the intensity is given by

\frac{I_{0}-I''}{I_{0}}\times 100=\frac{I_{0}-0.375I_{0}}{I_{0}}\times100

= 62.5 %
