Expert Solution
Summary Introduction

Introduction:

Ecology is the branch of biology that deals with the relationship between organisms and their surroundings. Ecologists study and research various fields to manage biodiversity and solve problems related to environmental conditions, by collecting and analyzing relevant data.

## Answer to Problem 1TYK

The detailed field studies are conducted after the simulation of natural events.

### Explanation of Solution

Justification/explanation for the correct answer:

Option (b) states that field events are conducted after the simulation of natural events. Because mathematical formulas help in predicting about the natural events that are going to occur, mathematic fractals help in predicting the size, location, and timing of any natural event. This helps in conducting field events comparatively easier than doing it without mathematics. Hence, option (b) is correct.

Explanation for the incorrect answer:

Option (a) states that fieldwork or laboratory work is avoided after using the mathematical models. Use of mathematics helps in conducting laboratory studies and field events with various data related to the concerned work. Excluding the laboratory work does not help. So, it is incorrect.

Option (c) states that basic study about ecological relationships in nature is done by using mathematical models. Mathematics provides various formula to predict upcoming natural disasters and hazards. So, it is incorrect.

Option (d) states that data of fecundity and survivorship to construct a life table is collected by using mathematical models. The survivorship data is collected graphically from the survivorship curve. The fecundity is the fertility rate of an organism; the data fecundity is collected after observations and illustrations about a particular organism. So, it is incorrect.

Option (e) states that a population’s geographical ranges are determined by using mathematical models. Ecologists use live history of the organisms to determine the population’s geographical ranges. So, it is incorrect.

Hence, options (a), (c), (d), and (e) are incorrect.

Conclusion

Therefore, it can be concluded that ecologists use mathematical models to predict data about the natural upcoming events, before conducting any field events. A mathematical model does not provide any data about the fecundity and geographical ranges of a population.
