Investigation of Animal Behaviour

Extracts from this document...

Introduction

Investigation of Animal Behaviour An experiment was carried out to determine whether a particular animal prefers a dry soil environment to a wet soil environment. The animal used in this case was an annelid, Lumbricus, L.terrestris, commonly know as the earthworm. They usually habitat a moist soil environment and are nocturnal. Although they have no prominent sense organs, earthworms are sensitive to light, touch, vibration, and chemicals. There is a primitive brain) at the anterior end of the earthworm. Hypothesis I think that most of the worms will favour the wet soil and stay on that side of the container. My hypothesis is based on observations of earthworms coming to the surface on rainy days. ...read more.

They were all collected from a 1m of the garden and placed in a jar. The start time was recorded and after 15 minute intervals the numbers of worms in each half of the container were counted. Newspaper was placed under the container in case any of the worms escaped. My hands were also thoroughly washed after handling the worms. Both containers that the worms came in contact with were disposed of after the experiment. Results Table Time in Mins No. of worms on dry soil No. of worms on flat soil 15 3 3 30 2 4 60 1 3 75 4 2 90 2 4 TOTAL 12 16 Observations The worms moved relatively slowly hence the 15 minute intervals between each result. ...read more.

Conclusion

Conclusion The hypothesis was supported, I based my decision on evidence that I observed in the past i.e. on rainy days worms come to the surface of the soil. This may be because the worms can move better in wet damp soil or there may be more things about to eat in wet conditions or it maybe that the worms do not like to have their burrow flooded out. Further Work More experiments could be carried out possibly with a larger amount of worms over a bigger soil sample or continue the experiment over a longer period of time. The equipment used could also be more sophisticated. ...read more.

    Some animals have developed the use of tools in their search for food. Habituation . . . Habituation is a simple form of learning, where an animal after a time of being exposed to a stimulus stops responding. Although this is a simple form of learning it is a very important learning process in young animals.

    * Scientists say there are no differences in lab animals and humans that cannot be factored into tests. * Human life has greater value than animal life. * Few animals feel any pain as they are killed before they have the chance to suffer.

    I think when people actually do the research on what breed, or breeds, would be right for them and their lifestyle, before they decide what dog to get, that automatically means that dog and owner end up being a lot alike.

  1. An Investigation into the water quality of the River Banwell in

    Lakes start as oligotrophic lakes ever increasing its nutrients naturally into a eutrophic one by erosion and sediments being deposited by streams entering the lake, but if this increase is rapid due to human intervention local ecosystems suffer. What happens is that these extra nutrients initially increase plant, animal diversity and abundance.

  2. An investigation into whether varying light intensity at a stream affects the species diversity

    As habitats become more complex, such as the large variety of plant species in the stream and the varied substrate as shelter, the population density increases which leads to a natural emigration of prey from the defined area. With no sediment involved in the cycle it results in both population
