<h3>
Answer:</h3>
Biotic
<h3>
Explanation:</h3>
We are being tested on whether we can differentiate between abiotic and biotic factors in an ecosystem.
- We need to know that factors that affect living organisms in an ecosystem are classified into abiotic factors and biotic factors.
Then, what is the difference between abiotic and bioitic factors?
- Abiotic factors are non-living factors that affect living organisms in an ecosystem while biotic factors are living factors that affect organisms in an ecosystem.
What are examples of Biotic and abiotic factors.
- Examples of abiotic factors include wind, temperature, humidity, climate,. etc.
- Examples of abiotic factors include parasitism, mutualism, commensalism, etc.
How do we arrive at the answer to our question?
- A Paramecium swimming in a lake; this is a biotic factor.
- Because paramecium is a living organism which relates with other organisms in the lake ecosystem in various way.
This is a three step problem. Luckily, the mathematics are pretty basic since we need not worry about acceleration in this problem, as the speed at which Grace roller skates is constant.
We start with part one, the first data given.
Grace travels 55.5km going 15.5 km/hr. In order to find out how much time it takes for Grace to travel this far, we can use a kinematics equation.
Substitute some numbers in:
So from here, we would multiply both sides by "t":
And then divide both sides by 15.5:
Remember that this is in hours, as the original velocity given was in km/hr.
Then, we do the same for the second set of data, coming to:
Again, this is in hours.
Finally, to find the answer to how long it took Grace to do this, we simply add the above solutions together and discover that it took her 6.88 hours (multiply by 60 minutes to find out she roller skated for 412.8 minutes) to travel that far. Wow! Grace has some admirable endurance!
The ionic bond. This involves ions of opposite charge. Eelectrostatically charged bodies with opposite charges, + and -, attract one another. I hope this helps
