Which of the following members of the food chain are most alike?
primary consumers and omnivores |
|
herbivores and autotrophs |
|
producers and tertiary consumers |
|
scavengers and decomposers |
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.
