Answer the following question given this paragraph: Types of organisms that make glucose by photosynthesis are pictured in Figure below . They include plants, plant-like protists such as algae, and some kinds of bacteria. Living things that make glucose are called autotrophs ("self feeders"). All other living things obtain glucose by eating autotrophs (or organisms that eat autotrophs). These living things are called heterotrophs ("other feeders"). Q: What are living things that obtain glucose by eating self feeders called? Choices: - producers - chimeras - viruses - heterotrophs A:
heterotrophs

Answer the following question given this paragraph: A warm-air heating system uses thermal energy to heat air. It then forces the warm air through a system of ducts. You can see a diagram of this type of heating system in Figure below . Typically, the air is heated in a furnace that burns natural gas or heating oil. When the air is warm, a fan blows it through the ducts and out through vents that are located in each room. Warm air blowing out of a vent moves across the room, pushing cold air out of the way. The cold air enters an intake vent on the opposite side of the room and returns to the furnace with the help of another fan. In the furnace, the cold air is heated, and the cycle repeats. Q: A warm-air heating system uses what kind of energy to heat air? Choices: - atmospheric - nuclear - cosmic - thermal A:
(Answer)
thermal
