Question

why do ecologists count representative samples of a population and not the total population under study?
a to get a precise number
b because it is impractical to count all the members of the population
c because it is the way that ecologists study ecosystems
d to get an estimate before counting the whole population
e because a representative sample more accurately reflects the carrying capacity
question 2
2 points
schools of fish in a reef are an example of a ___ distribution.
a random
b linear
c spherical
d clumped

Explanation:

For Question 1: Counting total populations is often impossible due to size, mobility, or habitat complexity, so ecologists use representative samples as a practical alternative.
For Question 2: Fish schools are groups of organisms clustered together for protection or resource access, which defines a clumped distribution.

Answer:

Question 1: B. because it is impractical to count all the members of the population
Question 2: D. clumped
