Unit 2 - The Living World: Biodiversity TOPIC 2.1 Introduction to Biodiversity ENDURING UNDERSTANDINGERT-2 Ecosystems have structure and diversity that change over time LEARNING OBJECTIVE ERT-2.AExplain levels of biodiversity and their importance to ecosystems. ESSENTIAL KNOWLEDGE ERT-2.A.1 Biodiversity in an ecosystem includes genetic, species, and habitat diversity. What does biodiversityliterally mean (its word parts): _________________________________ Define the three levels of biodiversity: What level of biodiversity is illustrated in this drawing of a freshwater swamp? _________ __________ is the number one cause of organism extinction. Why? Genetic Diversity Species Diversity Habitat Diversity
ERT-2.A.5 Species richness refers to the number of different species found in an ecosystem. Circle the statement that describes species richness. Think about the Biomes. Name one Biome that would likely recover from an ecosystem disturbance relatively quickly. ________________ Why did you choose this biome? Name one Biome that would likely recover relatively slowly. ________________ Why did you choose this biome? Use colored pencils or markers to complete the drawing that models the bottleneck effect. Each color represents a genetic variation within a species. Explain why the first population was more resilient to environmental stressors than the current (after bottleneck) population. A temperate forest is home to broad leaf trees like oak and maple, along with many shrubs, ferns, and moss species. Animals include deer, opossums, racoon, and mice.. Within a particular species of frog, there is a lot of color variation. Brown, tan, green, and both speckled or solid. A saltwater march has high primary productivity, with hundreds of mangrove trees and thousands of Salt Hay Grass (Spartina patens) plants.
Unit 2 - The Living World: Biodiversity TOPIC 2.2 Ecosystem Services ENDURING UNDERSTANDINGERT-2 Ecosystems have structure and diversity that change over time LEARNING OBJECTIVE ERT-2.BDescribe ecosystem services. ESSENTIAL KNOWLEDGE ERT-2.B.1There are four categories of ecosystem services: provisioning, regulating, cultural, and supporting. LEARNING OBJECTIVE ERT-2.CDescribe the results of human disruptions to ecosystem services.
