To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)

Which of the following members of the food chain are most alike?

|
herbivores and autotrophs |
|
scavengers and decomposers |
|
producers and tertiary consumers |
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.
