If possible I'd say all of them except the fourth one down (parts of ecosystems are independant) but if not I'd say the most valid one is the second one down (healthy ecosystems help animals)

Some of the instruments used by meteorologists to study weather are:
1. Thermometer - this instrument measures the temperature of the air
2. Barometer - measures atmospheric pressure
3. Anemometer - measures the speed of the wind. Some anemometers also measure the direction of the wind.
4. Hygrometer - measures relative humidity (the amount of moisture in the air).
The correct order is:
<span>C. Soviet Union begins a war with Afghanistan
</span><span>E. Mikhail Gorbachev becomes the leader of the Soviet Union
</span><span>A. Reforms such as glasnost and perestroika instituted in Soviet Union.
</span><span>D. Soviet government attempts to overthrow Mikhail Gorbachev
</span><span>B. Boris Yeltsin becomes president of the established Russian Federation</span>
