Question

name
how does energy affect an ecosystem’s organisms?

1. how huge is the sun?
2. nuclear fusion reactions combine multiple atoms to form what?
3. only a fraction of the enormous amount of energy that the sun emits makes it to earth. what percentage of the energy emitted by the sun reaches earth?
4. different places receive different amounts of what depending on latitude and time of year?

Explanation:

1. The Sun is extremely large. It has a diameter of about 1.39 million kilometers and is about 333,000 times the mass of Earth.
2. Nuclear fusion reactions in the Sun combine hydrogen atoms to form helium atoms. This process releases a vast amount of energy.
3. Only about 0.00000045% of the Sun's emitted energy reaches Earth. The Sun emits energy in all directions, and Earth is a small target in space.
4. Different places receive different amounts of solar - radiation depending on latitude and time of year. Higher latitudes receive less direct sunlight compared to lower latitudes, and the tilt of Earth's axis causes seasonal variations in solar - radiation.

Answer:

1. The Sun has a diameter of about 1.39 million kilometers and is about 333,000 times the mass of Earth.
2. Helium atoms.
3. About 0.00000045%.
4. Solar - radiation.
