Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which saves water.
Nitrogenous waste in the body tend to form toxic ammonia, which must be excreted. Mammals such as human excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste in the form of a white paste or power. The production of uric acid involves a complex metabolic pathway that is energetically costly in comparison to processing of other nitrogenous wastes such as urea or ammonia, it has the advantages of reducing water loss and, hence, reducing the need for water.

Answer:

Lionfish are rapidly consuming many smaller fish species along the coast at depths up to 90 meters.

Explanation:

Lionfish is an invasive species that has been successfully established in the Atlantic Ocean. It is a tropical species that lives mostly in reefs and rocks that provide protection. It inhabits waters from the coast to 50 meters deep.

Because of its high densities in the Atlantic, Lionfish is a promoter of ecological, economic, socio-cultural consequences. They only have a few predators and consume a high diversity of prey items. They produce an ecological imbalance in the trophic chains of the marine ecosystem. When competing with native piscivores, they imbalance the dynamics of fish communities in coral reefs and mangroves. The density of young and herbivores fishes has decreased because of their predation by the lionfish. By predating on algae eating fishes, they provoke a sharp increase in algae populations, which produces serious damages in the coral reefs, enhancing their mortality. The main consequences of these damages are marine biodiversity loss, water quality decrease, ecosystem recovery difficulty, and impacts on food provisioning for many other ocean species.

In environments that lack oxygen, some organisms have developed a way to break down intorganic molecules in order to produce ene

Ierofanga [76]

The above mentioned process is called as Anaerobic respiration 

Explanation:

All organisms need oxygen to produce energy but in some prokaryotes and eukaryotes they lack the presence of oxygen in their environment. Hence they have adapted a strategy called anaerobic respiration to break down the inorganic molecules to produce energy.

They use carbon dioxide and release methane as the by product. The process of glycolosis helps. All types of fermentation happens anaerobically here. It helps down to break down the fuels and produce energy. This energy is utilized for their life function.
