Document Summary
The physical environment ultimately determines where organisms can live, and the resources that are available to them. Terrestrial biomes y terrestrial biomes are characterized by the dominant growth forms of vegetation y biomes are large biological communities shaped by the physical environment, particularly climatic variation. The potential distributions of terrestrial biomes differ from their actual distributions due to human activities y human activities influence the distribution of biomes y y the potential and actual distributions of biomes are markedly different. Land use change: conversion of land to agriculture, logging, resource extraction, urban development. The potential distributions of biomes differ from their actual distributions b/c human activities have altered so much of earth s land surface. Biomes: tropical rainforests, tropical seasonal forests and savannas, hot deserts, temperate grasslands, temperate. Shrublands and woodlands , temperate deciduous forests, temperate evergreen forests, boreal forests, tundra y biome has constant temp. and high rainfall y.
