nonliving, chemical and physical components
temperature, precipitation, sunlight, and wind in an area
a major type of ecosystem
upper part of aquatic biome, sufficient light for photosynthesis
below photic zone of an aquatic biome, not much light
bottom aquatic biome, made of sand and inorganic sediments
dead organic matter, source of food
narrow layers of abrupt temperature change in an aquatic biome
shallow, well-lit area close to shore in an aquatic biome
aquatic biome, water too deep to support rooted plants
nutrient-poor and oxygen rich
nutrient-rich and oxygen deficient
habitat inundaned by water at least some of the time
plants dependent on water-rich soil
