No, it doesn’t occur in
the same organelle or organism. Chloroplast is the organelle where Photosynthesis
occur, while Mitochondria is the organism/organelle where cellular respiration occur.
Photosynthesis happens in the plant kingdom called for example a sun flower
uses the process of photosynthesis to make food for itself. Cellular respiration
is a chemical process in the mitochondria that makes energy out of sugar and
oxygen creating ATP.
There are several ice ages that has taken place here on earth. Recent studies of ice ages have interpreted glacial events by analyzing the oxygen isotope ratio in marine sediments.
- The Ice Age is a very popular timeframe in history. It is known to be a long time of decreasing in the temperature of Earth's surface and atmosphere.
This can also lead to the presence or expansion of continental and polar ice sheets and alpine glaciers.
The Earth's climate is said to often alternates inbetween ice ages and greenhouse periods. In this period, there will be no glaciers on the planet.
Scientists have recorded at least five important ice ages in the Earth's history.
