Serhud [2]2 years ago
5 0

Answer:

A coral reef is a reef-shaped structure in the sea, formed by anemones and which over time becomes large enough to have a significant ecological and physical impact on its environment. These are the largest structures built from living organisms in the world.  Coral reefs are complex marine ecosystems. They are a biotope (area of ​​life) of a biocenosis (community of living beings) consisting of plants and animals, for example worms, shellfish, sponges, thorns and crustaceans. Coral reefs play a significant role as “breeding grounds” for the offspring of fish inhabiting the high seas.

Discuss the effects of global trade on countries​
vladimir1956 [14]

Answer:

Global trade can have many fundamental effects on countries around the world. International trade results in the rapid development of countries and infrastructure. In addition, global trade can introduce new products and materials to countries, increasing development. This exposes countries to a variety of goods and services that were previously unavailable in their domestic economies. Imports from other countries also tend to lower consumer prices, which has a positive effect on global economies. Overall, global trade is central to the economic development of countries worldwide and positively impacts quality of living.

<span>The famine triggered by the "Great Leap Forward" was one of the largest man-made disasters in human history. Estimates of the number of casualties vary greatly and are difficult, if not impossible, to verify. Conservative estimates assume that from 1958 to 1961, over 14 million people died of starvation, and the number of reported births was about 23 million fewer than under normal conditions. Other authors have estimated the number of famine-related death of up to 30 million or higher

Which of the following are implicated as drivers in global amphibian decline:
likoan [24]

Answer:

B. All of these are drivers

Explanation:

The populations of lot of amphibians, with rare exceptions, are constantly on the decline around the world. The main reason behind this is the human activity, as it has caused lot of changes, pollution, and dangers for the amphibian populations, which has led lot of amphibians to be on the verge of extinction.

The pollution, especially of the waters, has been a major factor for the decline of the amphibian population. Lot of very toxic chemicals have made the water unsuitable for living and poisonous, which systematically killed off the amphibian populations.

The habitat loss, as with any other group of animals, has left the amphibians without places to live. They have been left without their shelters, food sources, mating grounds, and they have started to die out.

The invasive species, especially the predatory ones, have also had big negative impact. The amphibians didn't had any defense mechanism against the introduced predators, so they were easy prey and their numbers rapidly went down.
