Living systems are open self-organizing life forms that interact with their environment. These systems are maintained by flows of information, energy and matter. Some scientists have proposed in the last few decades that a general living systems theory is required to explain the nature of life.
Answer;
-illegal logging.
Explanation;
-Monarch butterfly migration is the phenomenon where the subspecies Danaus plexippus plexippus migrates each summer and autumn to and from overwintering sites on the West Coast of California or mountainous sites in Central Mexico.
-The monarch butterflies will spend their winter hibernation in Mexico and some parts of Southern California where it is warm all year long. If the monarch lives in the Eastern states it will migrate to Mexico and hibernate in oyamel fir trees.
-Illegal logging does not only bring threat to the Monarch butterflies but as well as to other animals living in that forest.
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.
