Correct Answer: plant products

Solution : The correct option is - plant products

Using the earth's net primary production (NPP) as a starting point, one can examine the carrying capacity of the planet. This is the entire solar energy that the photosynthesis of plants has transformed into biochemical energy, minus the energy those plants use for their own metabolic processes. It stands for the entire global food supply. Plant products can support a large population base even now, when deforestation and other types of vegetation damage are common.
