Answers

Answer:

4

There are 4 significant figures because when there is not a decimal, then only numerical values over 0 are counted. So the numbers counted in sig figs are 2049, and none of the other 0s.

So if it was 204,900,000,000.0, then it would have 12 significant figures.

Claim: An ecosystem can survive with only producers.


Do you agree or disagree with this claim? Explain your answer. Be sure to include evidence and reasoning.

Answers

Answer:

No.

Explanation:

The reason for this is if everything in an ecosystem was a producer there would be nothing consuming and soon the ecosystem would be overwhelmed by two many products and nothing to consume them. A healthy ecosystem is a balanced cycle that makes sure everything is working properly and everything benefits something else. A food chain of sort is often seen in a balances ecosystem to show how everything is useful and needed. So in answer if there were only producers an ecosystem wouldn't thrive at its full potential, if at all.

Water quality tests show the presence of a single heavy metal in the drinking water pulled from a local river. Residents are suffering from numerous stomach ailments and are showing signs of long-term kidney damage. The residents of the next town, down river from the first town, seem to be unaffected. Water quality tests in the river by the second town show two types of heavy metals at acceptable legal limits in the water. One of the metals is the same as the one in the first town. What can scientists infer about the possible reason for the illnesses appearing in the first town but not the second?

One metal causes an acute effect, compared to the other.
One metal causes a chronic effect, compared to the other.
The heavy metals have a synergistic relationship when combined.
The heavy metals have an antagonistic relationship when combined.
