Answer:
The three types of organisms in an ecosystem are producers, consumers, and decomposers.
Producers get their energy by using sunlight to make their own food from water and carbon dioxide through photosynthesis.
Consumers get their energy by eating plants and animals for food as they cannot make their own food.
Decomposers get their energy by eating/scavenging and breaking down dead and decaying plant and animal bodies.
Hope that helps.
Answer:
One triple bond and four non bonding electrons
Explanation:
In considering the lewis structure of carbon monoxide, we must remember that the molecule contains a total of ten valence electrons. Four are the valence electrons that are present on the valence shell of carbon while six are the valence electrons on oxygen. Some of these valence electrons participate in bonding in the CO molecule.
Out of the six valence electrons on oxygen, two valence electrons participate in bonding with carbon while the other four electrons remain localized on the oxygen atom as two lone pairs of electrons.
Hence there are four nonbonding electrons in the lewis structure of CO as well as one triple bond.
The correct answer is - 1 cm/yr.
Alongside the western coast of South America, the Nazca plate and the South American plate are in a collision for several million years now, with the Nazca plate being the one that is subducting in this convergent plate boundary.
If the Nazca plate's focus has moved 1,000 km in the last 10 million years, than in order to get to the annual movement of the subduction we need to convert the km into cm first:
1 km = 10,000 cm
1,000 x 10,000 = 10,000,000
1,000 km = 10,000,000 cm
Than we need to divide the number of cm with the number of years:
10,000,000 / 10,000,000 = 1
And we get the result of 1 cm/yr.
The value of the given expression up to correct significant figures is 
.
- The rule that applies for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
- The rule that applies for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
Given:
The expression: (23.4m)(14m)
To find:
The answer up to correct a number of significant figures.
Solution
Number of significant figures in '23.4' = 3
Number of significant figures in '14' = 22
The number with the least significant figures is '14' is 2, so the answer will be reported up to 2 significant figures:
Number of significant figures in '330' = 3
The value of the given expression up to correct significant figures is .
