Answer:
6 koalas
Explanation:
<em>The maximum number of koalas that can survive in the area is 6.</em>
Each koala must eat 200 grams of leaves per day.
The trees in an area can provide a total of 1380 g of leaves per day.
The maximum number of koalas that can survive in this area would be the total amount of leaves production per day divided by the amount of leaves required by each koala per day.
Hence:
Number of koala the area can support = 1380/200 = 6.9
<em>Remember that each koala must eat 200 grams per day, therefore, the maximum number of koala that can survive in the area approximately 6.</em>

What Question i can help if you want me to
The answer is D: A gradual change in a species over time.
Amplitude
Energy
Explanation:
The amplitude is the height of the wave and measures the amount of energy it carries.
Amplitude of a wave is the maximum amount of displacement of wave from rest.
The energy of the a wave is the amount of disturbance a wave transmits.
- The amplitude of a wave is the wave height.
- It measures the vertical height through which a wave passes through.
- Waves that have a high vertical displacement i.e high amplitude carries a lot of energy.
E = kA²
where E is wave energy , k is the wave number and A is the amplitude of the wave.
