Answer:
Paleozoic
Explanation:
The first insect fossils are dated to the Devonian, but because of the development of the genetics, the scientists have been able to trace the appearance of the first insects in the Ordovician. The insects originated from the crustaceans. Initially they were walking on land, but they hadn't developed wings. The wings came to develop in some insects in the Devonian, and since than it has gradually became one of their trademark features. It is interesting that the first insects actually appeared at the same time with the first terrestrial plants, and also that they are the first organisms to develop wings and be able to fly.

</u>
- Measures like the proper disposal facilities and food standards should be maintained as guided by the WHO and UNEP, checking the source is a most essential precaution that can be taken along with more awareness programs the stare and the local governments.
Answer:
Upwelling is<u> a process in which deep, cold water rises toward the surface</u>. How displaced surface waters are replaced by cold, nutrient-rich water that “wells up” from below. Conditions are optimal for upwelling along the coast when winds blow along the shore. Winds blowing across the ocean surface push water away.
Explanation:
Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers such as phytoplankton.
