Answer:
Magnetic Declination
Explanation:
Magnetic declination, or magnetic variation, is the horizontal plane's angle between magnetic north and true north. This angle varies depending on the position on the Earth's surface and changes over time.
They use it to convert into C6H12O6 ( glucose) through photosynthesis. Then other living things consume the plant/ algae and use it to go through cellular respiration and make ATP. The energy travels up the food chain as other animals eat the herbivore/omnivore.
