what parts of the food web are affected when an orangutan become endangered?
Answer:
On average, 2,000 to 3,000 orangutans are killed every year. While exact orangutan population counts are always a challenge – estimates put current counts between 50,000-65,000 orangutans left in the wild.
At this rate of loss, many experts believe orangutans could be extinct in the wild in less than 50 years.
Never before has their very existence been threatened so severely. Economic crisis combined with natural disasters and human abuse of the forest are pushing one of humankind’s closest cousins to extinction.

In the electrolysis of aqueous nabr, which substance is first produced at the anode?
NaBr is a soluble salt. When you dissolve the solid in water it will first separate the íons: Na+ interact and is surrounded by about 6 water molecules, and could be now represented by [Na.6H2O]+, still a positive íon; the Br- will also separate from the Na+ and interact with water molecules (typically 4–6), forming the [Br.nH2O]-, a negative íon.
What is produced at the anode in aqueous electrolysis?Oxygen is produced (from hydroxide ions), unless halide ions (chloride, bromide or iodide ions) are present.
In that case, the negatively charged halide ions lose electrons and form the corresponding halogen.
Thus, this the answer.
