Science Homework HELP!?

Question

What are the three main nutrients a plant needs to grow?

What happens to the plant if it doesnt get enough of these nutrients?

Answer 1

Nitrogen:

Older leaves, generally at the bottom of the plant, will yellow. Remaining foliage is often light green. Stems may also yellow and may become spindly. Growth slows.

Phosphore:

Small leaves that may take on a reddish-purple tint. Leaf tips can look burnt and older leaves become almost black. Reduced fruit or seed production.

Potassium:

Older leaves may look scorched around the edges and/or wilted. Interveinal chlorosis (yellowing between the leaf veins) develops.

Answer 2

NPK- Nitrogen Phosphates and Pottassium dont know what they do to make the plant grow but yeah these are the three that you need
