C is correct. the rest is either about food webs or about both food webs and food chains.
Out of the following given choices;
<span>A)
</span>They are all of the same species.<span>
B) They all require the same type of food.
C) They are part of a community.
D) They are abiotic factors in a forest.</span>
The answer is C. A community is
the summation of all the species population interacting in a habitat/ecosystem.
These interaction between the population could include commensalism, predation,
symbiosis, parasitism, and etcetera.
The best estimate of the population of trout in the lake is 500 individuals.
The low number of tagged trout recaptured may be because the tags slipped off.
This possibility can be reduced if the student used tags that does not slip off easily.
<h3>Mark and recapture method</h3>
The formula for calculating the estimated number of individuals in the population is given as:
where:
- N = estimated Number of individuals in the population
- M = number of individuals captured and Marked
- C = total number Captured the second time (with and without a mark)
- R= number of individuals Recaptured (those with a mark)
Calculating the estimate trout population:
N = (50*40)/4
N = 50
Therefore, the best estimate of the population of trout in the lake is 500 individuals.
The low number of tagged trout recaptured may be because the tags slipped off.
This possibility can be reduced if the student used tags that does not slip off easily.
