100 POINTS PLEASE HELP im doing research on australian rabbits

1. Where is this organism found?

2. How was this organism transported to its new ecosystem? Was it intentionally transported, and if so, for what reason?

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

4. What is the effect of this organism on the ecosystem’s current food web?

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

6. Are there any plans for controlling or removing this organism?

1. Australia, except in the northernmost areas.

2. 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. 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. 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. 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.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," says Mutze.

i used to know but i learned it a long time ago sorry

explanation:

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
