Farmers consider pesticides and fertilizers necessary to ensure successful farming. What problems are caused by the use if these
agricultural pollutants? The increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
Pesticides seem to pose no environmental problems.
The increase greenhouse gases.
The answer is <span>The increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.</span>.
Algae blooms are the consequence of large amounts of farm
fertilizers in the rivers, which increases nitrates level in the water. Algae use the presence of increased nutrients
and enhance their own growth. It is known that they produce
an oxygen in the photosynthesis, so it is not a problem while they are
still alive. But when these organisms die, their decomposition begins. For the
process of decomposition, the oxygen is needed and ultimately it will be depleted
from a body of water. This could lead to the death of aquatic animals, such as fish, that
depend on oxygen.
A. The increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
Is chemistry for reactions to take place energy must be provided. As heat is a form of energy, the more the heat, the more the energy, the faster the reaction occurs
They replace the lost ions by active uptake through active transport
of ions from the surrounding waters. This is exhibited in freshwater fishes that
actively take in these ions through the gills. Most of the ions involved in osmoregulation in freshwater are those of Na+ and Cl-.
