There are a few very good reasons why the change in the ice mass results in a decline in the populations of penguins. One reason is the penguins food source grows and develops under the the ice masses. Another reason is a loss of habitat for the penguins. When there is less ice, there are fewer krill for the penguins to eat.
Answer:
1. Global warming is the change in the climate of the earth causing it to heat up whereas the greenhouse effect is a naturally occurring phenomena, constantly occurring due to the atmosphere and sunlight.
2. Carbon dioxide absorbs heat radiating from the Earth's surface and re-release it in all directions—including back toward Earth's surface.
3. Decomposition, ocean release and respiration.
