D. diversity of the resources in the habitat.
Explanation:
The deforestation brings in lot of problem, much more than it brings in benefits for the humans on the long run. Once a forest is totally destroyed, the habitat suddenly loses the majority of its resources, especially for the organisms that are consumers. The soil too gets rapidly degraded, so the majority of the producers too find it very hard and takes them long time to reestablish themselves.
Having the diversity of resources dwindle, the organisms suffer badly. All living creates need resources in order to survive, so once they don't have them they die out. This unfortunately happens all over the world, with the tropical rainforest habitats being the most endangered, especially in the Amazon, Congo, and Southeast Asia.
Answer:
Polarity is the distribution of electric charge over the atoms joined by the bond.
Meaning:A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
Causes: Viral infections occur when a virus enters the body and invades the inside of the body's cells in order to reproduce. If the body's immune system is unable to fight off the virus, it multiplies and spreads to other cells, repeating the process and leading to a widespread infection.
