6 0

Answer:

Correct answer is False.

Explanation:

Cambrian explosion refers to period of geological history of our planet in which most of the multicellular organisms appeared in fossil layers. That was some 540 million years ago.

This period indicates that multicellular organisms began to develope in the early Paleozoic era. Before that much of the living organisms were singlecellular. Cambrian is the first period of Paleozoic era and it lasted between 540 and 485 million years ago. It is followed by Ordovician Period.

The bottom line is that Cambrian explosion is related with 'great occurrence of new and developed species'.

Many marine organisms depend on upwelling to bring nutrients to the surface. How might El Nino affect a fisherman's way of life?
Evgen [1.6K]

Answer:

The upwelling of seawater refers to the rising up of the deeper and cold water towards the surface of the sea. This cold water is comprised of the valuable and essential nutrients and as they move upward, it provides these nutrients to the marine organisms.

El Nino is usually defined as the large-scale changes in the climate that occurs due to the interaction between the ocean and the atmosphere. It leads to the episodic rise in the temperature of the sea surface, which typically occurs in the central and the eastern part of the central Equatorial Pacific.

The occurrence of El Nino leads to the reduction of the upwelling of deep-sea cold water. During the time of this harsh climate, the fishes die or they sometimes migrate into some other places where they can obtain their food. Due to this, the fisherman cannot go fishing.

Thus, the occurrence of El Nino directly affects a fisherman's life.
