I’m pretty sure it’s b only a guess
There are some reasons which could be mentioned:
1)Energy is lost as heat at each feeding level
2)Consumers who feed directly on plants have more energy for themselves than consumers feeding on other consumers. Indeed, energy again is lost in each level.
3)Feeding cattle is not productive, because energy must be transferred from plants to the cattle and then to people.
Answer: A!
Explanation: All biological organisms play a part in the earth's ecosystem, but consumers get energy from eating other organisms and producers make energy on their own. Grass is a producer, a self-sustaining organism that obtains its energy from the sun. In the process, it introduces new organic substances into the food chain and plays a key role for consumers. Grass forms the basis of the food chain because of this ability.
