Light and nutrients. Light is the key abiotic factor which controls the growth of woodland. It controls the spacing of the trees‚ shape of the trees and the shape and structure of the shrub and ground layers. If a trees branch does not receive enough light it will die. Irelands native woodlands are deciduous so there is a dramatic variation of the amount of light which reaches the forest floor through the seasons. In spring when the leaves have yet to grow and the temperature has begun to rise the

Animals‚ plants‚ and humans all share the same thing they have a will to live in different ways maybe or some might want to live

to investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1. Growth rates for pine seedlings in Batch I Experiment

Mung Bean Growth with Different pH Levels Through this experiment‚ the objective was to find which pH liquid created the best environment for the Mung beans to grow. First‚ the beans were placed into bags with different pH liquids. Then‚ measurements were taken each day to monitor the growth average of the beans. The pH 2 beans average size at the end of the experiment were 0.24 cubic centimeters‚ the pH 7 size average was 0.38 cubic centimeters‚ and the size average of the pH 2 beans was 0.24

Our experiment consisted of different levels of Windex mixed with water and given to Brassica Rapa plants in order to grow. Are results showed that Windex barely had an effect on the plant growth and the plants showed steady increase in growth. In conclusion‚ our experiment did not assure that Windex add a boost in plant growth but we did find that small‚ insignificant amounts of Windex

concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day‚ the largest concentration of salt will harm the plants the most. First‚ the plants were purchased and the water was prepared with the salt concentrations. Second‚ the plants were watered each day with the different concentrations of salt. Third‚ the plants’ growth were observed and recorded each day
