Plant Competition
INTRODUCTION

This experiment was used to show the different types of competition between species. Competition was defined as being a “relationship between members of the same or different species in which individuals are adversely affected by those having the same living requirements, such as food or space” (Competition 2010). There are two different types of competition that we will be observing during this experiment. The first type would be intraspecific, which means “competition between same species” (1976). The second type of competition is interspecific, which is defined as “competition between different species” (1976). These two types of competition have helped us look at the different types of interactions

Both beans seem to be equal because they were both able to produce the same amount of sprouts. However, the bean high had a higher variance and larger leaves which means it would ultimately be the better competitor than the bean mixed.
Bean Biomass | Bean High | Bean Mixed |
Mean | 2.179086957 | 2.74425 |
Variance | 0.513809083 | 1.511945137 |
Observations | 23 | 22 |
df | 43 | |
t Stat | -1.893943263 | |
P(T<=t) two-tail | 0.064972236 | |
t Critical two-tail | 2.016692199 | |
The significance is to show that this is an example of interspecific competition, which shows that the bean mixed is the better competitor because it had the higher biomass and variance. Although the bean high had more observed, the bean mixed would be the better competitor.
Radish Biomass | Radish High | Radish Mixed |
Mean | 1.294145455 | 0.379421053 |
Variance | 0.295494694 | 0.044617702 |
Observations | 22 | 19 |
df | 39 | |
t Stat | 6.889790538 | |
P(T<=t) two-tail | 3.03728E-08 | |
t Critical two-tail | 2.02269092 | |
The significance is to show that this is an example of interspecific competition. The radish high is the better competitor in this case because its biomass was larger and variance. This means that the radish high would be the better
