Question

Changing the Ecosystem
A food chain is a series of links between plants and animals. It starts with a plant. The next part of the link is a plant eater. When
the prairie plants started to die or be replaced with houses and roads, the animals that depended on them lost their food source.
So while the farmers produced more food for people, they broke the animals' food chain and the animals died or hold to move.
This was a great mistake. We are paying for that mistake today. And, unfortunately, people still keep making that mistake. They
keep breaking the food chains.
A food chain is part of a bigger system called a food web. That web links the living things in an ecosystem. The herbivores in
that system depend on the plants. If the plants are removed, the herbivores cannot survive. Then the carnivores, the animals that
eat other animals, lose their food, too. Remove just one kind of plant from an environment and you disrupt the food web. Plow
up the land and you destroy the whole system. The problem was there were more and more people and less and less natural
habitats.

Answer 1

The structure of the passage above impact the meaning of the text in a sense that, the author provides details about the ecosystem in the order that they occurred.

Answer: Option B.

Explanation:

In the above passage, the author have describes the food chain, its process, and how humans are destroying the ecosystem which affects the environment in whole. If we have a look at the structure of the passage, we will get to know that the author have provided acute details about the ecosystem in the order that they occurred.

Firstly the author have described what food chain is. Later he have made use of words such as ‘It starts with’ and ‘the next part’ which depicts the order of the ecosystem. It can’t be option C because the author have no where made a comparison or distinction between the parts of ecosystem. It also cannot be option A because no solution have been provided. Even option D is not possible because the passage do not list the causes much.
