Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Butter melting on a hot day is caused by heating. But breaking a piece of glass is not. Both are caused by cooling. Neither change is caused by cooling.

Which of the following organisms is the omnivore in this food web?

[ "silver maple", "beaver", "gray fox", "pine vole" ]

D

Omnivores are consumers that eat both producers and other consumers. So, an omnivore has arrows pointing to it from at least one producer and at least one consumer. The pine vole has an arrow pointing to it from the persimmon tree, which is a producer. The pine vole also has an arrow pointing to it from the swallowtail caterpillar, which is a consumer. The pine vole eats a producer and a consumer, so it is an omnivore. The black bear has an arrow pointing to it from the persimmon tree, which is a producer. The black bear also has arrows pointing to it from the swallowtail caterpillar and the beaver, which are consumers. The black bear eats a producer and consumers, so it is an omnivore. The beaver has only one arrow pointing to it. This arrow starts from the silver maple, which is a producer. So, the beaver is a consumer but not an omnivore. The silver maple does not have any arrows pointing to it. So, the silver maple is not an omnivore. The gray fox has two arrows pointing to it. These arrows start from the swallowtail caterpillar and the pine vole, which are both consumers. So, the gray fox is a consumer but not an omnivore.

What do these two changes have in common? breaking a piece of glass butter melting on a hot day

[ "Both are only physical changes.", "Both are caused by heating.", "Both are chemical changes.", "Both are caused by cooling." ]

A

Step 1: Think about each change. Breaking a piece of glass is a physical change. The glass gets broken into pieces. But each piece is still made of the same type of matter. Butter melting on a hot day is a change of state. So, it is a physical change. The butter changes from solid to liquid, but it is still made of the same type of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Butter melting on a hot day is caused by heating. But breaking a piece of glass is not. Both are caused by cooling. Neither change is caused by cooling.
