Introduction

Plan I am going to measure the size of various leaves from various trees with different heights and sizes. I am also going to find out the circumference of the tree and the length (measurements) of the branches. In order to achieve this goal, the use of a Quadrat would be useful. Throw the Quadrant in three different positions; record what species of plants and bugs were found in that certified area of the Quadrant; measure the plants (preferably 10 plants) and count the leaves on each plant's branch. Prediction I predict that the parts of the plants will absorb more sunshine, leaving a bigger quantity of leaves and a larger surface area of branches. ...read more.

Middle

After we threw the Quadrat three times, we managed to identify the individual plants which consisted of smaller grass and more/less bugs. We then used the compass to direct us towards a tree in a certain area. Once we had finished clarifying the types of grass, we then decided to analyse a small tree. We measured it (branch length) with the meter ruler and counted the number of leaves. (Results in table beneath). After counting the number of leaves, we began to witness many bugs, especially ladybirds on the leaves, so we took that information into thought. Table of Results Branch Length Number of Leaves Condition 52 103 Lots of sun, nutrients, space to grow 122 107 Lots of sun, nutrients, space to grow 72 ...read more.

Conclusion

This is because the areas with shade don't contain enough photosynthesis to keep a plant alive, which doesn't help a bug, when it needs to feeds on a plant. For example Bees get nectar and pollen from flowers (have a lot of sun rays) so the flowers need to be situated in the right area, where there is sun and need to be flowered regularly. This process is known as the biotic environment. Conclusion As you can see from the Graph (above) the branches length doesn't need to have a huge amount of leaf dues to its conditions. This proves that the trees condition doesn't need to have a lot of sun or shade to have a huge number of leaves. Paul Akinniranye 01/05/2007 ...read more.

  1. Discuss the various adaptations of vertebrates that enable them to live in marine conditions.

    These serve to reduce the separation of the boundary layer and backfill (pressure drag) in the wake of the body. In water the effects of this are even more pronounced and so the aim of aquatic vertebrates is to control turbulence, rather then eliminate it.

    Thus, shaded leave having adaptations for capturing the low intensities of sunlight are not designed for optimal photosynthesis when given full exposure to direct sunlight. Leaves that are not receiving much light grow bigger in order to absorb as much light as they can, the larger leaf size, is almost

    Also there is moisture on this side of the tree trunk. These are all the things algae needs to grow and all of them were found on the north side of the tree. I also did a Chi-squared test both my results from both sites were rejected therefore the reason

  2. In this coursework I am going to find out if trees modify the environment.

    There might be less living ground cover in the coniferous wood because coniferous trees are very tall so they might cover most of the light. If there is insufficient light plants cannot photosynthesize therefore they cannot live. I think that there will be less light in the coniferous wood than
