Blackberries, Moss/Lichen, English ivy, Giant Horsetail, Herb Robert and Sword Fern. • What is your hypothesis? Invasive plants are more likely to crop up on paved pathways than on dirt pathways because of human contact and interaction. • Why is it an important question to study? It is important to study because invasive species introduction causes harm to the native plants around them. They are outside of their natural distribution area, and secondly, threaten biological diversity. • What

temperature in the temperate zones, from freezing to extremely cold temperatures. It undergoes all the vicissitudes of seasonal climatic factors of wind, rain, and etc. (Elton, C.S., 1927). Elton, C.S. on his book on “The Ecology of Invasion by Animals and Plants, 1958” added that, the physical factors that affect grasslands include temperature, light intensity, wind direction and wind velocity, amount of rain or breeding places. First, temperature being an important factor affects animals inhabiting grasslands

Looking back, I remember running through the long lush grass pretending we were at battle and trying to take cover. I would always find myself behind the old oak tree in our back yard. This was my favorite spot. The thick trunk, like a bodyguard, protected me from the imaginary bullets that flew towards my body. I would lean against the hard bark and for some reason it was comforting to have something sturdy to lean on. It was dark brown, and every now and then a spider would nestle between the pieces

which plants transform solar energy into chemical energy, takes place in the chloroplast; furthermore, it is thanks to this chemical energy that plats produce seeds, grow and flower. However, chlorophyll is not a stable compound because sunlight causes it to decompose; hence, plants have to synthesize it continuously. Nevertheless, this "synthesis" requires sunlight and warm temperatures and that is the reason why it is scarce during autumn. Carotene is another pigment found in plants; it absorbs
