Given a scientific passage and an answer, generate a question for the given answer.

Input: Consider Input: Passage: Carbon moves through ecosystems in two cycles that overlap. In the biotic cycle, it moves between living things and the air. In the abiotic cycle, it moves between the air, ground, and oceans. By burning fossil fuels, humans have increased the amount of carbon dioxide in the air. Answer: biotic cycle

Output: In what part of the carbon cycle does carbon move between living things and the air?

Input: Consider Input: Passage: Hydraulic car lifts also use fluid to transmit pressure and increase force. The lifts are used to raise cars, which are very heavy, so mechanics can work on them from underneath. Controls in airplanes use fluids to transmit pressure and increase force so a flick of a switch can raise or lower heavy landing gear. To see animations of hydraulic systems such as these, go to URLs:. Answer: hydraulic systems

Output: What kind of systems use fluid to transmit pressure and increase force?

Input: Consider Input: Passage: Terrestrial biomes include tropical rainforest, temperate grassland, and tundra. Answer: terrestrial
Output: Tropical rainforest, temperate grassland, and tundra are examples of what type of biomes?
