Answer:
A.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.
An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.
Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.
