Effects of water scarcity on plants

• Water is very important for plant growth so its deficiency weakens the plant.
• When plants do not get sufficient water, they do not grow to their expected height, have reduced photosynthetic activity, and produce much less harvest than expected.
• Without enough water, plants will also be susceptible to diseases, which can eventually lead to the death of the plant.
• This may result in no food, no oxygen, and no rains and eventually end of all forms of life on the Earth.

Where do plants go when they die:

• A growing plant builds its tissue out of water, carbon and nitrogen compounds present in the soil and carbon dioxide from the air.
• When it dies and falls to the ground, its tissues are decomposed into simple compounds by the microbes present in the soil.
• This decaying plant matter is called humus.
• As humus decomposes, plant residues are converted into usable forms that are stored in the soil, and are taken up by living plants as food.
