Please help the subject is science
Use your research to write 3-5 well-constructed paragraphs that answer all of the questions. Your paper should be 1–1.5 pages long, double-spaced, using 12 pt. font. Make sure to list any sources you used in answering the questions (including the sources above, if used). the topic is austrailian rabbits
here are the Q&A
1. Where is this organism found?
These rabbits can be found in Australia. They live mainly in deserts and meadows.




2. How was this organism transported to its new ecosystem? Was it intentionally transported, and if so, for what reason?
Rabbits were first introduced to Australia by the First Fleet in 1788. They were bred as food animals, probably in cages. ... However, by 1827 in Tasmania, a newspaper article noted "...the common rabbit is becoming so numerous throughout the colony, that they are running about on some large estates by thousands.




3. Why is this organism able to spread so rapidly in its new ecosystem?

Rabbits were introduced to Australia in the 1800s by European settlers. Free from diseases and facing relatively few predators in a modified environment, the wild populations grew rapidly.


4. What is the effect of this organism on the ecosystem’s current food web?
Competition and land degradation by rabbits is listed as a key threatening process in Australia. Rabbits can cause damage by overgrazing native and sown pastures, leading to loss of plant biodiversity and reduced crop yields.



5. Is this organism affecting the lives of humans? If so, how?

Rabbits are not native to Australia and affect primary production and native ecosystems.
Their impact on primary industries includes:
Lost production (crops, pastures, and revegetation, horticultural or forestry seedlings),
Control costs, and
Soil erosion, and associated impacts on infrastructure and waters.
Their impact on native ecosystems includes:
Competition for food and shelter,
Selective grazing of preferred plant species, resulting in low or nil recruitment and subsequent ecological change,
Maintaining fox and feral cat populations, resulting in increased predation of native animals and contributing to the extinction of some species,
Soil erosion, and associated impacts on vegetation, wetlands and watercourses, and
Off-target harm from rabbit control measures such as baiting and fumigation.



6. Are there any plans for controlling or removing this organism?
Conventional and biological controls have been used in Australia to eradicate rabbits. Conventional controls include destroying rabbit burrows with poison and fire. Using poison, deep ploughing and then fuming burrows was highly cost effective [in] reducing rabbit numbers.

Answer:

1.Feral rabbits can be found in many different habitats across Australia, ranging from deserts to coastal plains — wherever there is suitable soil for digging warrens. They are scarce in areas with clay soils and abundant where soils are deep and sandy, such as in the north-east of South Australia.Abstract.

2.The European rabbit was brought to Australia as a companion animal by early settlers. ... In 1879 wild rabbits were deliberately sent to Victoria to provide game for wealthy settlers to shoot. They soon spread all over Australia, except in the tropics, and became Australia's major animal pest.

3.The zebra mussel is small, free-swimming, and easily spread by water currents, and can attach to almost any hard surface. ... The zebra mussel affects an ecosystem's food web both positively and negatively.
