Explanation:

QUESTION 1

The three factors that support life on Earth are the cycle of nutrients, solar energy, and gravity. Tectonic plates are related to Earth's structure and geological processes but not one of the three core factors for supporting life.

Decomposers break down dead organisms and organic matter, recycling nutrients back into the ecosystem so they can be reused by producers (like plants). This process is vital for nutrient cycling.

Answer:

b. Tectonic plates
