The answer is; C & E
Building a dam alters the water regime down the dam. The dam also affects fish migration along the river, alters the transportation of sediments by the river downstream, and changes temperatures within the local environment of the dam. These changes, however, the subtle effect the ecosystem around the dam and down the river. The potential energy of the water held by the dam is, however, high and used to produce more electricity.
Answer:
The biological carbon cycle
Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose. Heterotrophs, or other-feeders, such as humans, consume the organic molecules, and the organic carbon is passed through food chains and webs.
Explanation:
The best answer is "foreshocks before the quake and aftershocks after the quake".
These terms are used to characterise the events of an earthquake over time. Foreshocks are small shocks that can occur before the main seismic event. Aftershocks, like foreshocks, are smaller seismic events that can occur after the main seismic event.

The sign that shows food spoilage is bulging or leaking cans. That is option C.
Food substances can be stored or preserved to prolong the nutritive values and shelf life of the food.
Food spoilage occurs when environmental factors such as:
- Light,
- oxygen,
- heat,
- humidity,
- temperature and
- spoilage bacteria
causes food to become unsuitable for consumption.
For canned products, bulging or leaking cans shows the food content has deteriorated.
This shows some ongoing fermentation by a spoilage bacteria causing the can to bulge and eventually leak out.
Therefore, the sign that shows food spoilage is bulging or leaking cans.
