Ju.lia made a mis.take in her statement.
Answer:
No agriculture can take place in dry lands due to lack of water.
Explanation:
This is the statement that is not true of dry lands. It is true that dry lands are generally not suitable for large-scale agriculture. However, this does not mean that no agriculture can take place in them. People who have lived in dry lands for generations often farm in a small scale. Moreover, they grow crops that are resistant to this lack of water. Finally, some dry lands are significantly productive due to the use of artificial irrigation.
Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
