In the foood chain, producers serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through:
autotrophs |
|
photosynthesis |
|
chemosynthesis |
|
decomposition |
Producers (autotrophs) serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis

Most animals consume other organisms to survive. Consumers (heterotrophs) are divided into three types, primary, secondary, and tertiary, based on their place in the food chain.

Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg |
|
1 mph to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
The small intestine utilizes enzymes produced where?
all of these are correct |
|
pancreas |
|
liver |
|
small intestine |
The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls. These enzymes are produced in the small intestine as well as in the pancreas and liver. After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.
