1 answer:
antoniya [11.8K]3 years ago
5 0

Answer:

Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

Rina8888 [55]

Answer:

Dementia

Explanation:

Dementia is a condition that involves impaired mental ability and memory which is common among older adults. This condition, which is a major contributor to disability and placement of older adults in nursing homes, can be as a result of several factors of which nutrition has a major role to play. Metabolic and endocrine problem that results to the inability of the body system to regulate nutrients such as calcium and vitamin B-12, are some of the factors that triggers dementia in older adults. Also, nutritional deficiencies such as dehydration, inadequate intake of vitamin B-1, vitamins B-6, copper,vitamin E, and vitamin B-12 increases the chances of developing dementia in older adults.

Research shows that low levels of vitamin D can be linked to increased risk of developing dementia, and as such, supplements such as B-complex vitamin, vitamin C, and vitamin D is usually recommended for the prevention of dementia, especially when they are deficient in the diets taken.
