Hey there!
Answer: 400 k-cal
I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.
Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal
As we plug in this formula into our problem above, our answer would be explained below.
40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal
Answer: 400 k-cal

If the vibrations have a low frequency, the sound is heard as a __low-pitched sound_____. If the vibrations have a high frequency, then the sound is heard as a __high-pitched sound_____.
Explanation:
High pitched sound is of higher frequency because they make the air molecules vibrate much faster than low-pitched sound. Due to their high frequency, their wavelength is shorter (Remember wavelength and frequency are inversely proportional). Vice versa is true to the low-pitched sound. They vibrate air molecules slower than high-pitched sound. Their wavelength is longer and frequency smaller.

Sand should be your answer because it contains 5,0 premeability variation
An area where soil has eroded experience loss of nutrients. The topmost layer of soil is called the topsoil and is the most fertile. Soil erosion results in the loss of soil fertility and makes the land barren
The main cause of soil erosion is the removal of vegetation, which exposes the topsoil to water and wind. Wind and water are the main agents of soil erosion.
Water erosion can be sheet erosion, rill erosion, gully erosion or riparian erosion.
