represents the ways that life is organized and interacts on our planet. 2. What is ecology? Ecology is the study of organisms and their relationship with their surroundings. Ecologists study the interaction between an organism and its environment. Some ecologists study the interaction of a specific species or habitat; others study the different species that depend on each other (ex. a food web). 3. What is a biome? A biome can be described as an area on our earth that shares the same species‚ climate

Unlike ecozonse‚ biomes are not defined by genetic‚ taxonomic‚ or historical similarities. Biomes are
