Among ammonia, neon and copper,
Ammonia is a compound
Neon is an element
Copper is an element
Ammonia is a compound as it is made up of nitrogen and hydrogen that combines in a ratio that is 1 :3 to form 1 mole of ammonia.
And copper and neon are element as they consist of only one type of atom.
So the answer is that Ammonia is a compound
Neon is an element
Copper is an element
Answer:
1) sunlight
2) radiation
3) radiant Energy
4) heat
5) temperature
Explanation:
1) Solar energy is derived from the sunlight.
2) Now, solar energy gets to the Earth's atmosphere by electromagnetic radiation which warms the Earth's surface.
3) Sunlight is a form of radiant energy because the light from the sun is transmitted by radiation to the earth.
4) When sunlight reaches the earth it is converted to heat energy.
5) Due to the heat from the sun, it will increase the Temperature of objects.
In a food chain we arrange the energy in the form of a pyramid.
The producers are on the base of pyramid and then consumers are towards peak.
in the given food chain grass is being eaten by grasshopper which are food of birds.
Grasshoppers are also eaten up by Hawks. so both brids and hawks are feeding upon grasshoppers thus the amount of energy transferred from the grass to the grasshopper is the same as the amount of energy transferred from the grasshopper to the bird.
