Energy is destroyed because animals are higher levels do not need as much energy. That is option B.
<h3>Energy movement in a food chain</h3>
Food chain is defined as the sequence that shows the feeding relationship between different organisms and how energy flows from the producers to decomposers.
The producers which are the plants traps in energy from the sunlight with the help of their green pigment called the chlorophyll.
The energy continuously flows from the producers to consumers and then to the decomposers.
From the law of conservation of energy, it is neither created nor destroyed.
Therefore energy is destroyed because animals at higher levels do not need as much energy, is not a valid statement.

A) 10÷8.5
b) 120÷10
c) answer A÷Answer B.
sure on first two, not so sure on C.
The formula for the critical angle is:
sin (critical angle) = refractive index of solution / refractive index of air
=> refractive index of solution / refrative index of air = sin (48°)
=> refractive index of solution / refractive index of air = 0.7431
=> refractive index of solution = 0.7431 * refractive index of air
=> refractive index of solution = 0.7431 * 1.00
=> refractive index of solution = 0.74
Answser: 0.74
Answer:
Wavelength,
Explanation:
It is given that,
Speed of radio waves is
Frequency of radio waves is f = 101,700,000 Hz
We need to find the wavelength of WFNX’s radio waves. The relation between wavelength, frequency and speed of a wave is given by :
is wavelength
So, the wavelength of WFNX’s radio waves is 2.94 m.
