Explanation:

When there is deficiency in the normal calories intake, which is below the level required by organisms to survive, it means starvation.

It is known that human beings require about 1,200 calories a day to stay healthy, people with more strenous work need more calories.

The symptoms of starvation are but not limited to, low energy, constipation and/or diarrhoea, reduction in libido, increased food cravings.

It should be noted that prolonged starvation can cause permanent damage of organs and which may eventually results to death.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
