What is wrong with this step on the dichotomous key?
a) The animal lives in water ... go to step 6
b) The animal has fur ... go to step 7
Does not use physical characteristics, does not use yes or no/ have or have not questions or not mutually exclusive.

C
400
Which organism has the least amount of energy? The most?

A) It was discovered in the summertime
B) It is eaten by native jungle ants
C) Its leaves curl up on the edges
C) Its leaves curl up on the edges

What is wrong with this notation?

Identify the error in this food web
The arrows are not pointing the right way
500
In an energy pyramid, each trophic level has this percentage of the previous level's energy........
10%
500
Why does the energy pyramid grow smaller as it reaches the top?
Each higher level in the pyramid gets smaller because only about 10% of the available energy transfers to the next level.
500
Can a dichotomous key be used for organisms that are closely related? Why or why not?
Yes, but it might be more challenging because closely related organisms often have fewer distinguishing features, so the key must include very specific characteristics to differentiate them accurately
500
Is it possible for an organism to have BOTH the same Genus and Species as another organism?
Scientific names must be unique; if two organisms were given the same species name, it would create confusion. Rules of nomenclature prevent duplicate names to maintain clarity.
