1. Reduction in production costs due to absence of expensive chemicals and fertilizers.

2. Farm workers are healthier.

3. Saves energy.

4. Environment protection.

4. Advantages of relying on perennial crops

1. Perennial crops have better access to groundwater due to their deep roots.

Scilla [17]

Answer:

Option B, Move closer to your home town

Explanation:

The options for the given question are as follows -

A) Knock down your previous house and build a bigger one.

B) Move closer to your home town.

C) Move further away from your home town.

D) Stay where you are but speed up your daily life

Solution -

Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.  

While moving from a high energy orbital to a low energy level orbital, an electron releases some energy.  Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy

Hence, the given option is B
