classes |
|
kingdoms |
|

|
species |

50°F is how many °C?
-10 |
|
122 |
|
58 |
|
10 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)

cirrus clouds |

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