50 | INTRODUCTION TO ECOLOGY<br />
In this unit, we will examine ecology at these various levels. First, we examine biodiversity, which addresses all<br />
of the ecological levels. Next, we consider the broad levels of biosphere <strong>and</strong> ecosystem ecology by learning about<br />
nutrient cycling <strong>and</strong> climate change. Then we focus on community ecology, learning about the various ways<br />
that species interact with one another. Later, we consider population ecology, focusing on how population sizes<br />
change over time <strong>and</strong> the fac<strong>to</strong>rs that influence those changes. Lastly, we learn about evolution <strong>and</strong> modeling<br />
evolution using phylogenetic trees, which evolution occurs at the population level but is often influenced by<br />
biotic <strong>and</strong> abiotic fac<strong>to</strong>rs.<br />
