Unit 1- AP Environmental Science

Individual

Individual

One organism

Population

Group of individuals of the same species

Community

All living organisms in an area

Ecosystem

All living and nonliving things in an area

Biome

Large area with similar climate conditions that determine plant and animal species there

Biotic

Living organism

Abiotic

Nonliving organism

Symbiosis

Any close and long-term interaction between two organisms of different species

Mutualism

Different species benefit eachother

Commensalism

Different species where one benefits and other is not affected

Parasitism

Different species where one benefits and other is harmed

Competition

Reduces population because fewer resources available and fewer organisms can survive

Resource Partitioning

Different species using the same resource in different ways to reduce competition

Temporal Partitioning

Using a resource at different times

Spatial Partitioning

Using different areas of a shared habitat

Morphological Partitioning

Using different resources based on different evolved body features

Wetland

Area with soil submerged in water for part of a year, but shallow enough for emergent plants

Estuaries

Areas where rivers empty into the ocean

Coral Reef

Warm shallow waters beyond the shoreline and most diverse marine biome on earth

Intertidal Zones

Narrow band of coastline between high and low tide

Open Ocean

Only algae and phytoplankton can survive most of ocean

Photic Zone

Area where sunlight can reach

Aphotic Zone

Area too deep for sunlight
