The amplitude of wave 2 is double the amplitude of wave 1

At first glance, the amplitudes are the same (height of the waves).
It can be seen that Wave 2 goes up and down twice as much in one second as Wave 1. then, wave 2 has half the period and "twice as much as wave 1".

Starting from the sun, create a food chain including at least three organisms. Explain how energy is transferred through the cha

Kryger [21]

Answer:

The food chain showing seven organisms can be drawn as follows:

Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.

An energy pyramid for three of the organisms can be shown as follows:

mice (10 kilocalories)

↑

Grasshoppers (100 kilocalories)

↑

Plants ( 1000 kilocalories)

As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.
