Answer the following question given this paragraph: A food chain is a simple diagram that shows one way energy flows through an ecosystem. You can see an example of a food chain in Figure below . Producers form the base of all food chains. The consumers that eat producers are called primary consumers. The consumers that eat primary consumers are secondary consumers. This chain can continue to multiple levels. Q: What term is used to describe a simple diagram that shows one way energy flows through an ecosystem? Choices: - water cycle - food pyramid - fuel chain - food chain A:
food chain

Answer the following question given this paragraph: In the above equation for pressure, force is expressed in Newtons (N) and area is expressed in square meters (m 2 ). Therefore, pressure is expressed in N/m 2 , which is the SI unit for pressure. This unit is also called the Pascal (Pa) . It is named for the scientist Blaise Pascal whose discoveries about pressure in fluids led to a law of the same name. Pressure may also be expressed in the kilopascal (kPa), which equals 1000 Pascals. For example, the correct air pressure inside a mountain bike tire is usually about 200 kPa. Q: What unit of pressure is named for the scientist whose discoveries about pressure in fluids led to a law of the same name? Choices: - ohm - newton - joule - pascal A:
pascal

Answer the following question given this paragraph: Mollusks live in most terrestrial, freshwater, and marine habitats. However, the majority of species live in the ocean. They can be found in both shallow and deep water and from tropical to polar latitudes. Mollusks are a major food source for other organisms, including humans. You may have eaten mollusks such as clams, oysters, scallops, or mussels. Q: Clams, oysters, scallops, and mussels are examples of what type of species? Choices: - mammals - invertebrates - tortoises - mollusks A:
mollusks
