Worked Solution & Example Answer:A group of students carried out a line transect study to show the distribution of the daisy, a common wildflower plant, in a grassland habitat - Junior Cycle Science - Question a - 2017
Step 1
Using the results in the table, draw a suitable graph to show the relationship between the number of daisy plants and the distance from the tree.
Answer
To create a suitable graph:
-
Label the Axes:
- The x-axis represents the distance from the tree (in meters) with values from 0 to 8.
- The y-axis represents the number of daisy plants.
-
Scale:
- Choose an appropriate scale for both axes. For example, the x-axis can be scaled with intervals of 1 meter, and the y-axis scaled to represent the number of daisy plants, perhaps up to 10.
-
Plot Points:
- Based on the data provided, plot the points:
- (0, 0)
- (1, 2)
- (2, 3)
- (3, 5)
- (4, 7)
- (5, 8)
- (6, 7)
- (7, 6)
- Based on the data provided, plot the points:
-
Connect the Points:
- After plotting the points, connect them with a line to illustrate the trend in the distribution of daisy plants as the distance from the tree increases.
Step 2
Suggest a reason why there were no daisy plants in the first interval (Station 1).
Answer
There could be several reasons for the absence of daisy plants in the first interval (Station 1):
- Lack of Sunlight: Being very close to the tree may result in limited sunlight reaching the ground, which could hinder the growth of daisy plants.
- Nutrient Competition: The tree might be absorbing most of the nutrients from the soil, leaving insufficient resources for the daisy plants to thrive.
- Trampling: Frequent human or animal activity near the tree could lead to trampling, which would damage or uproot any potential daisy plants.
Step 3
Name another method that could be used to investigate the distribution of the daisy plant in a habitat.
Answer
Another method that could be used to investigate the distribution of the daisy plant in a habitat is a quadrant method. By placing quadrants of a fixed size at various points within the habitat, the density and distribution of daisy plants can be accurately measured. Another option is the belt transect method, which involves placing a long tape measure along a specific path and sampling plants at regular intervals along that line.
