What is the central idea of paragraph 3?

A.

The energy that plants create from sunlight can be seen by using satellites.

B.

C.

Satellites can help scientists learn more about plants and photosynthesis.

D.

It is important to understand why plants convert sunlight into sugar.

Answer 2

The central idea of the paragraph is: C. Satellites can help scientists learn more about plants and photosynthesis.

In the paragraph, the central focus revolves around the utilization of satellites by the space agency (NASA) to continuously observe and study the Earth's land and ocean life. It emphasizes how this vantage point from space aids scientists in monitoring the health of various aspects such as crops, forests, and fisheries worldwide. While not explicitly delving into the details of photosynthesis or the purpose behind plants converting sunlight into sugar, the primary concept is the application of satellite technology to gather insights about plant life, ecosystems, and their changes across continents and oceans.

Therefore, the core idea centers on how satellites enable scientists to enhance their understanding of plants and photosynthesis, as well as broader ecological systems on Earth.
