The type of interaction which takes place between all the five wildflower species that are enclosed with fences to keep out kangaroo rats, most common herbivores in the area. Introduction: When members of same or different species start living in a particular habitat, they show some effects on each other, these effects produced by organisms on each other are known as Biological interactions. These interactions may be short-term like predation or long term also like mutualism.

An ecologist studying desert plants performed the following experiment. She staked out two identical plots that included a few sagebrush plants and numerous small annual wildflowers. She found the same five wildflower species in similar numbers in both plots. Then she enclosed one of the plots with a fence to keep out kangaroo rats, the most common herbivores in the area. After two years, four species of wildflowers were no longer present in the fenced plot, but one wildflower species had increased dramatically. The unfenced control plot had not changed significantly in species composition. Using the concepts discussed in the chapter, what do you think happened?

Ernie's school has three greenhouses, located in three parts of the school. Ernie notices that the plants in one greenhouses are smaller than the same species in the other greenhouses. Ernie's biology teacher says she has been having a problem recently with growing plants in this particular greenhouse. Ernie's lab group decides to investigate factors such as light levels, temperature, and soil nutrients in the three greenhouses. They find that these are the same for all the rooms. What additional factors would you suggest testing for, and how would each of these factors affect the growth of plants? 20

In another experiment, fishes were placed in separate aquarium tanks with water coming from three different waterways in Los Baños. Three tanks were filled with water from each source and equal number of fish were placed in each tank. The tanks were refilled as required with water from the original sources. Two plant species known to be bioremediators were tested and compared with a control (no plants). Three tanks were assigned to each of the plant species and the control. After three months, a sample of fish was taken from each tank and evaluated whether the fish contains heavy metals above the threshhold(1) and 0, otherwise. Which is the most appropriate procedure to compare the plant species and the control? A. F-test B. t-test C. Cochran’s Q D. Friedman test
