RTW Monday March 26 th Choose one relationship

RTW Monday, March 26 th Choose one relationship and give an example of how it works: • Commensalism • Parasitism • Mutualism

Monday, March 26 th • Objective: I will be able to explain how limiting factors determine carrying capacity and influences a population’s size. • Agenda: • Finish Food Web Worksheet (from Friday- due today) • Carrying Capacity Worksheet (due tomorrow) • Vocab Ch. 14 • Homework: • Finish Worksheets

Tuesday, March 27 th RTW: How is an animal’s habitat different from their niche? • Objective: I will be able to describe the impact to an ecosystem’s loss of biodiversity. • Agenda: • Turn in Work • Food Web Worksheet (from Friday) • Carrying Capacity Worksheet (from yesterday) • Vocab Ch. 14 (from yesterday) • Notes- Threats to Biodiversity • Homework: • Finish Worksheets

KEY CONCEPT The impact of a growing human population threatens biodiversity.

Preserving biodiversity is important to the future of the biosphere. • The loss of biodiversity has long-term effects. • loss of medical and technological advances • extinction of species • loss of ecosystem stability

Loss of habitat eliminates species. • Habitat fragmentation prevents an organism from accessing its entire home range. • occurs when a barrier forms within the habitat • often caused by human development

• Habitat corridors are a solution to the problem. – corridors can be road overpasses or underpasses – allow species to move between different areas of habitat

Introduced species can disrupt stable relationships in an ecosystem. • An introduced species is one that is brought to an ecosystem by humans. • accidental • purposeful • Invasive species can have an environmental and economic impact.

• Invasive species often push out native species. – Burmese python (Florida Everglades)

• Invasive species often push out native species. – mice (Australia)

• Invasive species often push out native species. – kudzu (southeastern United States)

KEY CONCEPT Conservation methods can help protect and restore ecosystems.

Sustainable development manages resources for present and future generations. • Sustainable development meets needs without hurting future generations. • resources meet current needs • resources will still be available for future use

• The timber industry has started to adopt sustainable practices. • Global fisheries have adopted several sustainable practices. – rotation of catches – fishing gear review – harvest reduction – fishing bans

Conservation practices focus on a few species but benefit entire ecosystems. • The Endangered Species Act works to protect individual species from extinction. • A listed species is often called an umbrella species. • the habitat in which the species lives must be protected • other species are protected because they share the ecosystem

Protecting Earth’s resources helps protect our future. • The Environmental Protection Agency (EPA) was created in 1970. • The EPA develops policies and regulations to protect the environment. • Legislation helps to protect the environment and endangered species. • Clean Air Act • Clean Water Act • Endangered Species Act

• The National Park Service helps manage public lands. • The park system includes over 390 areas, covering 84 million acres.

• There are several ways that people can help protect the environment. – control population growth – develop sustainable technology and practices – protect and maintain ecosystems

Wednesday, March 28 th RTW: Give an example of an invasive species and how it effects the ecosystem. • Objective: I will be able to describe the impact to an ecosystem’s loss of biodiversity. • Agenda: • Turn in Work • Food Web Worksheet (from Friday) • Carrying Capacity Worksheet (from Monday) • Vocab Ch. 14 (from Monday) • Yellowstone- Climate Change Video • Yellowstone- Climate Change Questions • Homework: • Finish Worksheets

Thursday, March 29 th RTW: Name an organism and how they have been affected by climate change. • Objective: I will be able to describe the impact to an ecosystem’s loss of biodiversity. • Agenda: • Turn in Work • • Food Web Worksheet (from Friday) Carrying Capacity Worksheet (from Monday) Vocab Ch. 14 (from Monday) Yellowstone- Climate Change Questions (Wednesday) • Moth Activity • Homework: • Finish Worksheets

Peppered Moths • An example of evolution of a species over the past 200 years • Before the Industrial Revolution in England the trees were a mottled white color. • Coal burning factories began producing soot that covered the forests, making the trees black in color. • The peppered moth population responded to this change, by adapting to their environment

Moth Activity

Peppered Moth Simulation • Objective: Explain how natural selection causes populations to change • Working with your shoulder partner you will complete the lab and record your data on the handout as well as answer the questions. • Use your phone to time each other as you “eat moths”

Instructions • You will be given a moth outline • Cut it out • Color it (AT LEAST 2 COLORS) • Camouflage the moth for a specific surface around the room • Tape your moth to the surface and come to me (predator) and show what area it is in to see how well you camouflaged it
