Unit 2 - The Living World: Biodiversity TOPIC 2.1 Introduction to Biodiversity ENDURING UNDERSTANDING ERT-2 Ecosystems have structure and diversity that change over time LEARNING OBJECTIVE ERT-2.A Explain levels of biodiversity and their importance to ecosystems. ESSENTIAL KNOWLEDGE ERT-2.A.1 Biodiversity in an ecosystem includes genetic, species, and habitat diversity. ERT-2.A.2 The more genetically diverse a population is, the better it can respond to environmental stressors. Additionally, a population bottleneck can lead to a loss of genetic diversity. ERT-2.A.3 Ecosystems that have a larger number of species are more likely to recover from disruptions. ERT-2.A.4 Loss of habitat leads to a loss of specialist species, followed by a loss of generalist species. It also leads to reduced numbers of species that have large territorial requirements. What does biodiversity literally mean (its word parts): _________________________________ Define the three levels of biodiversity: Genetic Diversity Species Diversity Habitat Diversity What level of biodiversity is illustrated in this drawing of a freshwater swamp? _________ __________ is the number one cause of organism extinction. Why?
ERT-2.A.5 Species richness refers to the number of different species found in an ecosystem. Circle the statement that describes species richness. 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. 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.
Unit 2 - The Living World: Biodiversity TOPIC 2.2 Ecosystem Services ENDURING UNDERSTANDING ERT-2 Ecosystems have structure and diversity that change over time LEARNING OBJECTIVE ERT-2.B Describe ecosystem services. ESSENTIAL KNOWLEDGE ERT-2.B.1 There are four categories of ecosystem services: provisioning, regulating, cultural, and supporting. LEARNING OBJECTIVE ERT-2.C Describe the results of human disruptions to ecosystem services. ESSENTIAL KNOWLEDGE ERT-2.C.1 Anthropogenic activities can disrupt ecosystem services, potentially resulting in economic and ecological consequences.
