PLZ HELP I NEED THE ANSWER SL I CAN STUDY according to the diagram how much energy is stored in the boards trophic level if the producer has 3452 kcal?

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat. If a grassland ecosystem has 10,000 kilocalories (kcal) of energy concentrated in vegetation, only about 1,000 kcal will be transferred to primary consumers, and very little (only 10 kcal) will make it to the tertiary level. Energy pyramids such as this help to explain the trophic structure of an ecosystem: the number of consumer trophic levels that can be supported is dependent on the size and energy richness of the producer level.

Explanation:

thanks me later :)

the answer is b: 1.4 km/hr

i believe the answer is a or 1
