How can a shortage of nutrients harm organisms in an ecosystem? How can an excess of nutrients harm organisms in an ecosystem? G
professor190 [17]

Answer:

Explanation:

Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.

For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.

Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.

For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .

tamaranim1 [39]

Answer:

The Central Nervous system is made up of the brain,the control units,and the spinal cord ,the network of nerves ,which feed the brain with sensory information  for processing.The entire CNS is lined by a constantly circulating fluid called the Cerebrospinal Fluid.(CSF).

Together with the Peripheral Nervous system,the CNS ensure coordination of the body activities.

Generally both  the brain and the spinal cord are protected by the skull and vertebral column respectively. Their activities are based on the million of neurons which are networked by synapses.

Functions are:

processing information that is received from the stimuli receptors

sending out information so that the body can react appropriately to stimuli

coordinating reflexes and reactions to stimuli.

These functions are performed through the fast reflex  pathways, for efficient  coordination of the systems of the body by the CNS with PNS
