Answer:
pesticides
Explanation:
One major theme of the <em>Silent Spring</em> is the negative power of humans to affect natural world by polluting and making it lethal with the use of pesticides. Carson argues that pesticides have harmful effects on food, on wildlife and on humans. The author gives the example of DDT which is a prime killer and goes on to blame the chemical industry of deliberately spreading wrong information.
The book explores the effects of pesticides on natural ecosystems, on foods that humans consume which lead to cancer and other serious diseases. Critics said that Silent Spring changed the balance of power in the world since many policy changes came into force in the use of DDT and other pesticides and environment-policy changes. <em>Silent Spring</em> helped cause a reversal in the US' national pesticide policy, which led to a nationwide ban on DDT for agricultural uses. It helped create the US Environmental Protection Agency in 1970.
Answer:
A symbol from the Diary of Anne Frank is Anne's grandmother.
Explanation:
A symbol is a person or thing that represents an abstract concept or idea and one of the powerful symbols in the Diary of Anne Frank is her own grandmother. Her grandmother signals unconditional love and nostalgia for her life before the Nazis came to power and Anne's life was turned upside down. Anne’s grandmother appears to her in her dreams. To Anne, her grandmother symbolizes support but also makes Anne feel some regret or remorse because she wants to talk with her grandmother as before and she misses her life prior to having to go into hiding. Anne regrets not telling her grandmother she loves her more frequently. She sees her grandmother as her guardian angel watching over her and she can turn to the idea of her grandmother when she feels particularly afraid or uncertain.
Answer:
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms. A food chain is a linear sequence of organisms through which nutrients and energy pass as ... When we're talking about their role in food chains, we can call autotrophs producers.
Energy must constantly flow through an ecosystem for the system to remain stable. What exactly does this mean? Essentially, it means that organisms must eat other organisms. Food chains (Figure below) show the eating patterns in an ecosystem. Food energy flows from one organism to another. Arrows are used to show the feeding relationship between the animals. The arrow points from the organism being eaten to the organism that eats it. For example, an arrow from a plant to a grasshopper shows that the grasshopper eats the leaves. Energy and nutrients are moving from the plant to the grasshopper. Next, a bird might prey on the grasshopper, a snake may eat the bird, and then an owl might eat the snake. The food chain would be:
plant → grasshopper → bird → snake → owl.
A food chain cannot continue to go on and on. For example the food chain could not be:
plant → grasshopper → spider → frog → lizard → fox → hawk.
Food chains only have 4 or 5 total levels. Therefore, a chain has only 3 or 4 levels for energy transfer.
How do the grasshopper and the grass interact?
Grasshoppers don't just hop on the grass. They also eat the grass. Other organisms also eat the grass, and some animals even eat the grasshopper. These interactions can be visualized by drawing a food web.
