Introduction

Biology First hand investigation & Field study techniques By Liam Blackbourn 11 Bio First hand investigation and field study techniques By Liam Blackbourn Year 11 Biology The purpose of my investigation is to accurately measure the abundance and distribution of one animal and plant species from the Thirroul/Austinmer rock platform, a local ecosystem. I aim to achieve experience and gain knowledge in the function of methods used when measuring the abundance and distribution of these biotic factors. The animal species I have chosen in the Black Periwinkle (Melanerita Melanotragus) and the plant species, Neptunes Necklace ( Hormosira banksii I strive to measure the distribution and abundance of each other these species as accurately as possible. Methods The methods I chose to use measure these factors include: 1. ...read more.

Conclusion

Abundance: Both these species are rather abundant in this area as it is an ideal marine rock platform environment. There are numerous pools of water where both species can happily live, and flat rocks covered in nutrients for the Black Periwinkles to live on. Conclusion: By using a transect line a square quadrat, I was able to successfully measure the abundance and distribution of both a plant and animal species. investigating many areas for the abundance makes the results very accurate, and by starting the transect line in a different environment to where it ends clearly shows where the best place for the species to live is. The results clearly outline regions in which the species can easily live e.g. where there is most water. The results also show that a rock platform is a great place for these species to live and reproduce. ...read more.

    If any of these animals dies, the decomposers will be going in anytime and decompose any of them to provide nutrients for grass. This in turn creates a merry-go-round food chain which will make the person who makes the food chain have a hard time to find a place for decomposers.
