Communities, Biomes, and Ecosystems
Section 1: Community Ecology Section 2: Terrestrial Biomes Section 3: Aquatic Ecosystems

Limiting factors and ranges of tolerance are factors that determine where terrestrial biomes and aquatic ecosystems exist. K What I Know W What I Want to Find Out L What I Learned Copyright © McGraw-Hill Education

Section 1: All living organisms are limited by factors in the environment.
Section 2: Ecosystems on land are grouped into biomes primarily based on the plant communities within them. Section 3: Aquatic ecosystems are grouped based on abiotic factors such as water flow, depth, distance from shore, salinity, and latitude.

Essential Questions How do unfavorable abiotic and biotic factors affect species? How do ranges of tolerance affect the distribution of organisms? What are the stages of primary and secondary succession? How is latitude related to the three major climate zones? What are the major abiotic factors that determine the location of a terrestrial biome? How are the terrestrial biomes distinguished based on climate and biotic factors?
