Answer 2

The empty space or blank needs to be filled with Sunlight.

Explanation:  The flow of energy in the given food chain is shown as:

• Sunlight-----> plants ------> herbivores------> carnivores.
• The flow of energy is defined as the energy that passes in the trophic levels of a food chain in the ecosystem.
• The flow of energy passes only in one direction, hence, it is unidirectional.
• When an organism receives energy from a source, it utilizes that energy for the maintenance and metabolism processes of its body and passes the remaining energy to the next trophic level.
• The main source of energy is sunlight which is absorbed by the plants for the preparation of their food and then is transferred to the herbivores who eat plants.
• From the herbivore animals, this energy passes to the carnivores who prey on the herbivore animals.
• Therefore, the flow of energy passes from the lower trophic level of the food chain to the higher trophic levels of the food chain.
