The rabbits had no natural predators in Australia.
Explanation:
- 'The rabbits were affected by many limiting factors.' This could not be a possibility because the limiting factors have a negative impact on growth rate of population. The limiting factors hinder the growth of population so if there were too many limiting factors affecting the rabbit, then the growth in population was not possible.
- The rabbits reproduced by asexual reproduction. Rabbits are mammals and it is a known fact that they reproduce sexually. Thus this option is not possible.
- The rabbits were unable to adapt to the environment If the rabbits were not adapted to the environment then they must not have survived efficiently in Australia. Hence, this is not a possibility.
- Thus, the only possibility that remains is that , The rabbits had no natural predators in Australia' Otherwise, the predators would have preyed upon the Rabbits and there population must not have increased in this rate.
Answer:
15,000 from green plants to rabbits
1,500 from rabbits to weasels
150 from weasels to eagles
Explanation:
10% of the energy is being passed on from one level to the next, it goes as 150,000 to 15,000 to 1,500 to 150 to 15 to 1.5 to 0.15 to 0.015 and so on. (hint just move one zero to get the answer much easier)
Weight is determined by the effect of gravity on an object, which relates to the mass of the object. The moon has less mass than the Earth, and therefore the gravitational pull is less strong, meaning that the weight is less.
D. Watershed - a watershed is the area in which runoff, rivers, and streams run into a larger body of water
1 possible future is The Big Crunch. This theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting.
2. Some theorists state that the expansion of the universe will go on forever, and if that happens, the universe will cool as it expands, and then it will become too cool to sustain life.
3. The Big Rip. The universe may keep expanding, as I mentioned before. But as it expands, the gravity may not be able to hold all the planets together, as it is now. Galaxies would tear apart first, followed by smaller black holes, planets and stars. Eventually, space would start expanding faster than the speed of light, and atoms would start breaking down into super small particles and everything would fall into nothing.
