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 .

Explain why the metric system and si are important​
Dovator [93]

Answer:
In simple terms, the metric system (which is the same as SI) is important because it's more coherent than the imperial system.

Explanation:

The metric system is far more used worldwide compared to the imperial system, where the imperial system is only officially used in three countries (U.S, Liberia, Myanmar).

There are multiple reasons why the metric system is important, but the most critical reason is that it's very easy to understand pertaining to calculations. The measurement system of SI is <em>designed</em> to make measurements/calculations easy to perform and understand. This is why scientists prefer using the metric system over imperial.

You can make some small comparisons:

--> Metric is consistently based on decimal numbers, while imperial uses different number systems (base 3, 8, 12, 14, 16, etc.,)
--> Metric works well with percentages, while imperial does not
--> Metric units are the same internationally, while some imperial units differ (i.e different pints, gallons, tons, etc.,)

There are fewer, simpler measurements in the metric system as compared to imperial where calculations start to get overcomplicated due to the amount of measurements/units in the system.

In layman's terms... metric is a boat on smooth water with perfect weather, while imperial is a boat on rough waters during a storm.
