Question

What is major threat to survival of organosms

Answer 1

A constantly changing physical environment requires organisms to adapt to new temperatures, climates, and atmospheric conditions. Living things must also deal with unexpected events such as volcanic eruptions, earthquakes, meteor strikes, fires, and hurricanes.

As new lifeforms arise and interact, species are further challenged to adapt to one another to deal with competition, predation, parasitism, disease, and other complex biotic processes.

Answer 2

Biodiversity is under serious threat as a result of human activities. The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation.
