Grassland Investigation-Does Light Affect The Distribution Of Daisies?

Extracts from this document...


Grassland Investigation-Does Light Affect The Distribution Of Daisies? Planning Many different factors affect the distribution of plants, and many factors affect the population of animals in different areas. Physical factors and Biotic factors affect these. They can vary from differences in soil fertility, oxygen levels, pressure, temperature, disease, availability of food, colonization and migration. All these affect the level of plants and animals found in one particular area. In this test I am going to see if the level of sunlight affects the distribution of daisies and other plants found in that area. To do this I have found two almost identical areas of grassland within the boundaries of the school. One of these areas has an overhang from the trees next to it, meaning the grass is almost constantly shaded. The other area is very open and has all the advantages and disadvantages of open grassland. I have chosen these 2 areas because they are both flat, although certain parts of the area must not be included as they are sloped. ...read more.

This will be excluding Yarrow as I only occurred in Area 1. Comparison of Daisies Comparison of all plants Conclusion I have found that more plants are found in Area 1. This is because of what I said in my Planning and prediction. Not only sunlight affects the growth of plants but so does the level of water it can get, with an over hang of trees much of the rain water never reaches the ground and therefore there is less water to collect. ...read more.


The results gained are reliable enough to produce a conclusion on whether light effects the number of daisies. But I do not think this data is reliable enough to strongly say that is this factor which affects the growth of daisies, as the amount of water is affected by the overhang meaning area 2 would get less water to area 1. To check that my results are reliable and to gain extra results you could plant seeds in soil and deprive one area of land of light, only a little can get through, while the other part has plenty of light. You could do this with trays of soil with plant seeds in, also they must have access to water otherwise are results will not be fair. To see if water affects the growth of plants we could do that same experiment except they get equal amounts of light, but the amount of water they get varies between the trays. This could be done to find out what factors affect plant population the most and what factors don't affect the plant numbers. ...read more.
