Answer:
The primary threats to chimpanzees are habitat destruction, hunting, and disease. The increasing human population is encroaching ever deeper into even protected areas of chimpanzee habitats, and large scale logging is now a major threat to the forest primates of Africa.
Explanation:
Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.
The decomposition of the whale enriches the sediment.
<span>When a whale dies, it falls to the ocean floor. Its dead body is known as whale-fall. This whale-fall provides nutrients for a whale-fall community, which includes bacteria, crabs, worms and other invertebrates. Organic fragments from the whale-fall enrich the sediments nearby. Enrichment opportunists colonize the whalebone and surrounding sediment in order to feed on these organic fragments.</span>
