Ecology Biology Notes GCE Study Buddy Ecology ● Ecology is the study of interactions among organisms‚ and between organisms and the physical and chemical factors making up their external environment ● Ecologists study both the non-living (abiotic) or physical environment‚ and the living (biotic) environment. Physical environment ● Amount of light ○ Light intensity affects the distribution and growth of both plants and animals ● Amount of water ○ Xerophytes are plants which can

Biology Revision notes Ecology: 1) Ecosystems‚ sampling and population studies Population: All the individuals of a given species living together in the same area and at the same time. Community: Community: all the individuals of all the species living together in the same area and at the same time. Habitat: The area in which an organism lives within an ecosystem Niche: describes where an organism lives‚ what it does (its role)‚ what it feeds on and how it interacts with other organisms and the

Ecology ➢ Climate is weather conditions of a region like temperature‚ humidity‚ precipitation‚ sunlight pressure‚ winds‚ throughout the year over a period of time ➢ Ecology – is the study of the interactions between organisms and the environment ➢ Abiotic factors –temperature and water ➢ Microclimate – a classification at the small scale variation ➢ Dispersal – movement away fro origin ➢ Macroclimate – a classification at the global and regional level

Biology has been the most interesting and appealing subject I have taken. Taking the course as a freshman‚ and the AP course as a junior‚ has really influenced my choice of a potential major. The course taught me how to be more studious and efficient with the information I retain. It is a puzzle‚ in which you piece together process by process‚ step by step. AP Biology also enhanced my collaboration skills. The course is very rigorous and challenging‚ and I struggled often trying to do it all by myself

Jill Payne Mrs. Healey Ecology March 7‚ 2011 Essay I have recently found several acres of land to plant my crops on although the land is not in the best condition. I have many concerns about planting on this land and thought of some measures throughout the upcoming years to improve the condition of my land. While thinking of these ideas to help improve my property I went back to the things I learned in the soil and agriculture chapters in my wonderful ecology class. I remembered how important

Meiosis is the process in sexually reproducing organisms where cells divide. The cells produced during meiosis have half the chromosome number as the original cell. There are two cell divisions in meiosis‚ meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only one set of chromosomes‚ which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in one diploid cell

AP biology FRQ Courtney DeMane 1.22.13 block 7 A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino‚ carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure‚ there are 4 levels. The first one being the primary level. These are made

With the evolution of animals living on land from animals living in the water‚ many changes needed to be made in order for survival. Each problem that these organisms may have experienced in the past has been dealt with a solution of some manner. One of the main problems was water storage. Because organisms in an aquatic environment are surrounded by water‚ they do no experience problems with water storage‚ but without an aquatic environment there are bound to be problems. The land organisms need
