Discuss in detail the impact of European farm animals on the ecosystems of Oceania. Why have the Dingo fence and the Rabbit Proof fence been necessary in Australia.? What does this tell us about the vulnerability of Oceania’s environment to invasive species, and toe changing patterns of food consumption based on introduced domesticated animals? Finally, why are coral reefs such as the Great Barrier Reef ecologically important to the coastal zones of Australia, and how are they threatened by climate change

Answers

Answer 1

The evolution of flora and fauna across the islands of Australia and Oceania is very unique.

Many species of plants and animals reached the southern Asian islands during the last ice age, when sea levels were low enough for travel. THE DINGO Fence was built to keep dingos out of sheep pastures in South East Australia. As Australia's largest terrestrial predator, dingoes pose a major threat to livestock.

The Rabbit Proof Fence was built to protect Western Australia's crops and grasslands from rabbit disease. Introduced to Australia in Victoria in the 1850s, the pest quickly spread throughout eastern Australia.

They are home to a quarter of the ocean's marine life, generate clean air and protect vulnerable coastlines from erosion, flooding and storms. In Australia, our Great Barrier Reef is an irreplaceable and vital part of our ecosystem - and our economy.

Explanation:

The living part of an ecosystem is known as a biotic factor or biotic component. The definition of "biotic" is "of or pertaining to biological beings." Any living thing that exists is a part of an ecosystem.

Non-living elements that have an impact on an ecosystem are known as abiotic factors, sometimes known as abiotic components. Despite not being living, abiotic influences can have an impact on the ecosystem's related living things.

What law suggest that the rock in the graphic did no go through any geological process after deposition because the strata are flat

Answers

Law of lateral horizontality or law of original horizontality.

The law of primordial horizontality states that all rock formations are initially deposited (deposited) horizontally and can be deformed later. from this, we can conclude that something must have happened to the rock that caused it to tilt. These include orogenic events, earthquakes, and faults.

Laws of geology?

Uniformity: the present is the key to the past.Pure horizontality: sedimentary layers are deposited first in horizontal strata. Superposition: the lowest layer is the oldest, and it gets younger as it accumulates.

The term, coined by William Whewell, was first proposed by English naturalists in the late 18th century as an antidote to catastrophe. It originated with geologist James Hutton starting his research in many of his books, including his theory of the earth.
