Which of the following members of the food chain are most alike?
scavengers and decomposers |
|
herbivores and autotrophs |
|
producers and tertiary consumers |
|
primary consumers and omnivores |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.

Which of the following is not true about mass and weight?
mass depends on the location where it is measured |
|
mass is the amount of matter something has |
|
weight is the force exerted on an object by gravity |
|
weight depends on the location where it is measured |
Mass is the amount of matter something has while weight is the force exerted on an object's mass by gravity. So, although a person's mass doesn't change when going from the Earth to the Moon, their weight will decrease because the force of the Moon's gravity is much less than that of Earth.
