Answer:
The second student is right.
Explanation:
The coyote feed on not only phalaropes but many other organisms present in the environment for its survival. There are many other organisms present in the ecosystem such as mice, squirrel, cactus fruit etc. The coyote feeds on phalaropes, the phalaropes feeds on brine shrimp and the brine shrimp feeds on algae for its survival so in this way the ecosystem moves in the forward direction. The coyote feeds on phalaropes so the energy that is present in phalaropes transferred into coyote which only 10 % while the remaining is released in the atmosphere in the form of heat energy.
Compared to visible light, an electromagnetic wave that has a higher wavelength will also have <u>a lower frequency</u>.
That's because frequency and wavelength are inversely related.
f ∝ 1/λ
When one goes up, the other goes down and <em>vice vesa</em>.
The answer is d cuz it’s doesn’t make a lot of the formula
