Arthropods were the first animals to successfully invade land from the sea
Answer:
Yes.
Explanation:
Yes, changes in the environmental conditions of a specific region result in formation of new ecosystems as well as the lost of old biodiversity occur because the organisms of that old ecosystem can't tolerate the change that occurs in the environment so they become extinct or migrated to another suitable place and only those organisms begins to live which can survive in that environmental conditions.
Arctic Foxes are animals who live in these cold enivorrment.
The answer is non-living and biotic. Non-living because the processes that characterize a living organism (such as respiration, growth, response to stimuli, nutrition, and etcetera ) cease in the tree. Biotic because the tree is still composed of molecules associated with life such as proteins, carbohydrates, cellulose, lignin, and etcetera, even though the tree is dead.
