University Makes Changes to Orientation Program

Madison University is making a change to the orientation program for first-year students. In the past, as part of orientation, new, incoming students could go on a two-day hiking and camping trip together with other incoming students on the weekend before classes begin. In order to encourage more students to take advantage of the opportunity to get to know one another in an informal setting, the university will now offer a choice of activities: students will be able to either go hiking or participate in organized group games on campus. Additionally, these activities will last one day only, not two, a change many students had requested.

问题

Population Changes

Populations of living beings are constantly changing. The number of humans, animals, insects, or plants living in a given area can vary because of two kinds of factors: biotic and abiotic. Biotic factors are living factors that can influence the size of populations, such as predators or other species competing for food. Abiotic factors are nonliving things in the surrounding environment that can cause population changes, such as weather or sunlight. Biotic and abiotic factors cause continual changes in the number of individuals that make up a population of organisms.
