The living world encompasses ecosystems, biomes, and their intricate interactions, forming the foundation of AP Environmental Science. This comprehensive guide explores terrestrial and aquatic ecosystems, biogeochemical cycles, and ecological relationships.

• The guide covers essential concepts from Unit 1 The Living World: Ecosystems including ecosystem structures, biotic and abiotic factors
• Detailed exploration of terrestrial biomes, freshwater ecosystems, and biogeochemical cycles
• In-depth analysis of ecological relationships and primary productivity measurements
• Focus on environmental challenges and human impacts on ecosystems

Page 2: Ecological Relationships

This page delves deeper into various types of species interactions and relationships within ecosystems, particularly focusing on symbiotic relationships.

Definition: Symbiosis refers to close, long-term interactions between two species in an ecosystem.

Example: Clownfish and sea anemones demonstrate mutualism, where both species benefit from the relationship.

Vocabulary:

  • Commensalism: One species benefits while the other is unaffected
  • Parasitism: One organism (parasite) benefits while harming the host
  • Competition: Organisms competing for limited resources

Highlight: Understanding different types of competition is crucial for ecosystem dynamics:

  • Intraspecific competition occurs between members of the same species
  • Resource partitioning helps species coexist by utilizing different parts of the environment

Page 3: Terrestrial Biomes and Climate

This page explores terrestrial biomes and their relationship with climate patterns, emphasizing the importance of environmental conditions in shaping ecosystems.

Definition: Biomes are large-scale ecological regions defined by climate, geology, soils, hydrology, and vegetation patterns.

Highlight: Hot, humid regions typically support greater primary productivity and biodiversity compared to cold or dry regions.

Example: Temperate seasonal rainforests exhibit all four seasons and are characterized by deciduous trees that change colors throughout the year.

Vocabulary:

  • Climate: Long-term patterns of temperature, humidity, atmospheric pressure, wind, and rainfall
  • Primary productivity: Rate at which energy is converted to organic substances by photosynthetic organisms

Quote: "Climate graphs show the relationship between annual precipitation and temperature across different biomes, from tundra to tropical rainforest."

Page 3: Terrestrial Biomes

The page details the classification and characteristics of land-based ecosystems, introducing the concept of biomes and their determining factors.

Vocabulary: Climate refers to long-term patterns of temperature, humidity, atmospheric pressure, wind, and rainfall in an area.

Highlight: Ecosystems are categorized into biomes and aquatic life zones based on climate, geology, soils, hydrology, and vegetation patterns.

Page 4: Grassland and Savanna Biomes

This section examines specific terrestrial biomes, focusing on savannas and grasslands, including their characteristics and distributions.

Definition: Savanna is a grassland biome with scattered trees found in tropical regions between deserts and rainforests.

Example: North American plains and prairies represent agricultural grasslands with sod-forming grasses.

Highlight: Shrublands feature shallow soil intermixed with small trees and spiny vegetation, typically found in coastal regions with hot, dry summers.

<h2 id="unit1thelivingworldecosystems">Unit 1: The Living World - Ecosystems</h2> <p>In this unit, we will be exploring ecosystems and biom

View

Page 5: Freshwater Ecosystems

The content covers various freshwater ecosystems and their importance to human society and environmental health.

Highlight: Freshwater systems are crucial for providing humans with water and food resources.

Definition: Wetlands are areas with water-saturated soil, shallow enough for emergent plants with roots in water.

Example: Lakes are lentic ecosystems (still water) with four distinct zones based on depth.

<h2 id="unit1thelivingworldecosystems">Unit 1: The Living World - Ecosystems</h2> <p>In this unit, we will be exploring ecosystems and biom

View

Page 6: Human Impact on Wetlands

This section addresses anthropogenic causes of wetland degradation and introduces the carbon cycle.

Vocabulary: Anthropogenic refers to environmental changes caused by human activities.

Example: Agricultural drainage, commercial fishing, and logging are major human impacts on wetlands.

Highlight: The carbon cycle involves exchanges between the biosphere, geosphere, hydrosphere, and atmosphere.

<h2 id="unit1thelivingworldecosystems">Unit 1: The Living World - Ecosystems</h2> <p>In this unit, we will be exploring ecosystems and biom

View

Page 7: Nitrogen Cycle

The page explains the nitrogen cycle and its importance in biological systems.

Definition: The nitrogen cycle is the cyclic movement of nitrogen between living organisms and the environment.

Highlight: Nitrogen comprises 78% of the atmosphere and is essential for making proteins and nucleic acids.

Vocabulary: Nitrogen fixation is the process of converting atmospheric nitrogen into biologically usable forms.

<h2 id="unit1thelivingworldecosystems">Unit 1: The Living World - Ecosystems</h2> <p>In this unit, we will be exploring ecosystems and biom

View

Page 8: Hydrologic Cycle

This section details the water cycle and groundwater systems.

Definition: The hydrologic cycle is the process where water moves between the atmosphere, oceans, lakes, rivers, and land.

Vocabulary: Aquifers are bodies of permeable rock that can contain or transmit groundwater.

Highlight: Approximately 70% of Earth's water is stored in oceans.

Page 1: Fundamental Ecosystem Concepts

This page introduces core concepts of AP Environmental Science and ecosystem structures. The content focuses on basic definitions and interactions within ecosystems.

Definition: An ecosystem is a community of living organisms interacting with their non-living environment as a system.

Vocabulary:

  • Abiotic: Non-living components including atmosphere, hydrosphere, lithosphere
  • Biotic: Living components including animals, plants, fungi, bacteria
  • Population: Group of organisms of the same species
  • Community: Different species populations in the same geographic area
  • Habitat: Environment where an organism lives
  • Ecological niche: Species' role in its environment

Example: Resource partitioning occurs when species share resources without conflict, demonstrating how organisms can coexist in the same environment.

Highlight: Symbiotic relationships play a crucial role in ecosystem functioning, with mutualism benefiting both organisms involved.
