Chapter 1 THE PROBLEM AND BACKGROUND OF THE STUDY Introduction We see plants all around‚ every day. We have been thinking how water travels through plant stems we do some studying and surfing in the internet we learned that water travel by absorbing through the roots and travelling through the plants’ vascular system. Surface tension and pressure help the water move its way through the plant. Statement of the problem 1. How many grams of

This new vegitation helps feed the animals that live within the forest‚ the small newly grown plants are both healthy for the large animals such as deer and stouts as well as it is providing food for the smaller occupants like mice and other small mammals. And because those herbivores get new

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

Basic Ecology Terms: Ecology- the study of how organisms interact with their environment Organism- a living thing that gets food‚ water‚ shelter‚ and other things it needs to live‚ grow‚ and reproduce from its environment Habitat- environment that provides needed things Biotic Factors- the living part of a habitat Abiotic Factors- the non-living part of a habitat (soil‚ oxygen‚ water‚ sunlight‚ temperature) Species- a group of organisms that can mate with each other and produce offspring that

IMPORTANCE OF FORESTS Introduction Trees are mankind lifeline. If they are destroyed‚ there is no way that human beings can survive. From the oxygen that we breathe in‚ the food that we eat‚ to the clothes we wear‚ we owe it all to the trees. Not only this‚ trees act as purifiers of air and receptacles of our waste products. Trees have great economic value too. We get fuel‚ fodder‚ timber‚ medicines and numerous other valuable products from the trees. It is‚ therefore‚ not surprising that trees

What is a biome? A biome is a large‚ distinctive‚ complex community of plants and animals in a region maintained by climate. There are different types of biomes including tundra‚ taiga‚ deciduous forest‚ scrub forest‚ grasslands‚ desert and rain forest. Scientists disagree on the exact number of biomes in the world.
