A lake community with four trophic levels suddenly suffers from algal blooms. Using the strategy of biomanipulation, an ecologist may propose removing zoonplankton.
Hope I helped.
A scientific theory is something believed to be true, thus already tested. When you make an observation you infer, and test your observations to see if they’re true. Please mark me brainliest if I helped :)
Turkey has been a crossroad for multiple cultures and an advantage of global economic exchange because of its excellent strategic location.
Explanation:
Turkey's territory has been place where numerous cultures interact and mix for millenniums. From ancient times, lot of different groups of people have been migrating through Turkey, or settling in Turkey. Such examples have been the:
- Dorric people
- Indo-Europeans
- Caucasus people
- Celtic people
- Balkan people
- Mongol people
- Turkic people
- Arab people
- Iranian people
- Italic people
All of these people have been creating a very mixed and interesting culture in Turkey, as all of them were interacting, mixing, adopting cultural traits from each other. One of the main reasons as to why so many different people have been moving into this territory has been the economic advantage. Turkey is connecting Europe and Asia, and the majority of the trade between these two continents was going through it, so whoever controlled the trade was having huge economic advantage. This trend has continued even in modern times, as Turkey is crucial in the trade between Europe and the Middle East, as well as controlling the Bosphorus, thus controlling trade between the Black Sea and Mediterranean Sea.

Answer:
The drag from wind holds the responsibility for driving ocean waves in addition to the surface tension.
Explanation:
The ocean currents at the first 100 m of its surface is moved by the wind drag. Whereas, the ocean currents flowing below the thousand meters of its surface are driven by water's density gradient, which is governed by thermohaline circulation, 'thermo' means temperature and 'haline' means salinity. The centrifugal force has no role to do in driving the ocean current in its surface and earth's rotation causes the Coriolis effect which is an example of hurricane winds.
Answer:
