The primary productivity (photosynthesis) can be define as the total production of organic matter in the form of carbohydrates from available atmospheric carbon dioxide and water in the presence of sunlight, appropriate temperature, and nutrients by the plants or other autotrophs. The life on earth sustains due to primary productivity as the plants prepare their own food and these plants are consumed by the animals and other living beings.

El compuesto SeO y HgO es: * óxido ácido y óxido básico óxido ácido y óxido ácido óxido básico y óxido básico óxido básico y óxi
Dmitriy789 [7]

Answer:

óxido ácido y óxido básico

Explanation:

Los óxidos son compuestos químicos formados por la combinación de un elemento químico con el oxígeno (O). Si el elemento que se combina es un metal, el óxido formado se denomina óxido básico. Por el contrario, si el elemento que se combina es un no metal, el óxido resultante es un óxido ácido.

Se (Selenio) es un elemento no metálico, por lo que su óxido (SeO) es un óxido ácido.

Hg (Mercurio) es un elemento metálico, por lo que su óxido (HgO) es un óxido básico.

How would controlling disease In commercial fisheries be both easier and more challenging?
djyliett [7]

<u>Controlling disease in commercial fisheries</u>

Explanation:

Disease outbreaks among fishes reared lead to economic loss to the fish farmers. Optimal conditions of the pond should be maintained to prevent disease spreading.

Control of disease is very challenging because fishes are cultivated in aquaponds at high density which increases direct contact among fishes making way for spread of the disease.

Natural predators will remove infected fish quickly but manual methods are time consuming and not effective.

Various steps which can be followed for prevention of diseases like good water quality, nutrition and sanitation facilities, stocking and storing of fish, recording each detail.

At the same time, disease control can easily be done by reducing the density of the stocks, application of vaccines and antibiotics and other drugs, mechanical administration of drugs, use of probiotics etc.
