Why is the loosening of soil important for plant growth?

It increases the acidity of the soil, which is beneficial for plants

It allows roots to easily penetrate deep into the soil (correct)

It helps in reducing water retention in the soil

It decreases the presence of earthworms and microbes

What role do earthworms and microbes play in the loosened soil?

They break down organic matter and add humus to the soil (correct)

They compact the soil, making it harder for roots to grow

They prevent water from reaching plant roots

They decrease the nutrient availability for plants

How do nutrients reach the plants after the soil is loosened?

Nutrients are carried by earthworms directly to plant roots

Nutrients are released into the air above the soil

Nutrient-rich soil is brought to the top layer accessible by plants (correct)

Nutrients are absorbed by the air in the soil
