Answer:
1. Both food chains and food webs show the flow of energy in an ecosystem. However, food chains illustrate one path of energy, while food webs show multiple paths of energy and interactions among food chains.
2. About 90 percent of the energy at each trophic level is lost and not available to the next level. If the producer level has 100 units of energy, then 10 units of energy are available for the primary consumers.
3. Green plants. Just as 90 percent of the energy at each trophic level is lost, the amount of biomass is typically highest at the primary producer level and decreases in higher trophic levels.
4. Energy is lost to the environment in the form of heat.

Passages:
"Remembering to Never Forget: Dominican Republic's 'Parsley Massacre’” by Mark Memmott:
Seventy-five years ago, thousands of Haitians were murdered in the Dominican Republic by a brutal dictator. It was one of the 20th Century's least-remembered acts of genocide.
As many as 20,000 people are thought to have been killed on orders given by Rafael Trujillo. But the "parsley massacre” went mostly unnoticed outside Hispaniola. Even there, many Dominicans never knew about what happened in early October 1937. They were kept in the dark by Trujillo's henchmen.
"A Genetics of Justice” by Julia Alvarez:
At this point I would always ask her why she and my father had returned to live in the country if they knew the dictatorship was so bad. And that's when my mother would tell me how, under pressure from his friends up north, Trujillo pretended to be liberalizing his regime. How he invited all exiles back to form political parties. How he announced that he would not be running in the next elections. My father had returned only to discover that the liberalization was a hoax staged so that the regime could keep the goodwill and dollars of the United States.
My father and mother were once again trapped in a police state.
Answer:
C. The passages show how people often did not know or understand the extent of Trujillo’s deceit.
Explanation:
The excerpts in ''Remembering to Never Forget: Dominican Republic's 'Parsley Massacre'' and in "A Genetics of Justice” we can see that they are showing that Trujillo's fraud and deceit was very unknown for other people.
In the first excerpt Mark Memmot is talking about massacre which was a genocide also unknown by many of them.
In the second excerpt Julia Alvarez is talking about lies that her parents did hear and they return under wrong expectation because of that.
