1]Well if the planets were removed the pray would have no food to eat, because of this the food chain would most likely die out, or the pray would need to find a new location with materials they can consume.
2]Explain how energy is transferred through food chains and food webs in an ecosystem. Energy is transferred through the separate trophic levels of a food chain or web by feeding.The first trophic level (producers) is that of plants which are examples of autotrophs – they make their own food.
Answer:
About redox reaction which of the given statements are true?
Explanation:
Redox reaction is the one in which both oxidation and reduction reactions take place simultaneously.
For example:
In this reaction, carbon undergoes oxidation and oxygen undergoes reduction simultaneously.
During this reaction, mutual exchange of electrosn take place between the oxidant and the reductant.
Among the given options,
Option B. electrons are transferred
and
option C.They include both oxidation and reduction takes place are the correct answers.
Answer:
1.47 M
Explanation:
First we <u>convert 86.00 g of NaCl into moles of NaCl</u>, using the <em>molar mass of NaCl</em>:
- 86.00 g ÷ 58.44 g/mol = 1.472 mol NaCl
Then we <u>convert 1000 mL into liters:</u>
Finally we can <u>calculate the molarity of the solution</u>:
- Molarity = moles / liters
- 1.472 mol / 1.0 L = 1.472 M
