In what way does plant nutrition differ from human nutrition? 

• Plants make their own nutrients; humans must consume theirs.
• Plant nutrition consists mainly of protein; human nutrition consists mainly of carbohydrates.
• Plants absorb their nutrients from the soil; humans get theirs from food.
• Plants cannot make their own food.
