Aseries of choices between two characteristics that is used to identify organisms is called a

a. characteristic chart.
b. characteristic key.
c. dichotomous chart.
d. dichotomous key.

The correct answer is option D, dichotomous key

Explanation:

Dichotomous keys are used to identify plant and animals and also it is an indicative parameter of relationship between two species. The dichotomous key consists of series of choices associated with questions one after the other which helps in identifying an organism. For example for identification of any plant, the first question would be “does the plant have leaves” with option either “yes” or “No”. If the answer to this question is yes, the next question will be related to some distinguishing characteristic of leaves. If the answer to this question is “no” a new set of question will come related to some other part of plant.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
