WORLD BIOMES

Ecology Class

Mrs. Dunnavant

World Biomes

Background: All of the livable space on the Earth makes up the biosphere.

A biome is defines as large geographic areas that have similar climates and climax communities.

World Biomes

The organisms (both plant and animal) that survive within a biome are uniquely adapted to that particular biome.

World Biomes

Goal: Students will work in groups to research

and present information on one of the world’s major biomes.

World Biomes

Objectives:1. Each group will use research and reading skills

to find out about one of the world’s biomes

2. Each group will orally present their biome to the class in PowerPoint. (upload to Mrs. Dunnavant’s school web page)

3. Each student will become familiar with the names and basic characteristics of the different biomes and the populations they contain.

World Biomes

Researching the Biomes1. 10 Groups representing major Biomes-

1. Tundra2. Coniferous Forest3. Deciduous Forest4. Desert5. Tropical Rain Forest6. Grassland7. Tropical Savanna8. Temperate Ocean9. Freshwater Biomes10. Marine Biomes

World Biomes

Become an Expert! (Requirements)

Major abiotic factors that affect life in this habitat

-rainfall, temperature ranges, amount of light, climate, pollutants

- example: climographs

World Biomes

Major biotic factors that affect life in this habitat

-plant and animal populations that are common in this biome

Some Biotic Factors

• parasitism • disease • Predation, food chain

World Biomes

Competition and Adaptation

- Explain how organisms are specifically adapted to this habitat. (ex. Koala hands adapt)

- Include plants and animals

- Describe how organisms within the same species and different species compete for resources

Resource level starts high, ends low

World Biomes

Human Influence- Explain how the human factor affects the biome. For example, logging, development, pollution.

Conservation Projects

World Biomes

PowerPoint Requirements: 12 slide minimum (including title and references) Create a worksheet for your classmates to answer during

your presentation

Each slide must have a minimum of one graphic but no more than three per slide.

Animation and/or sound effects included

Make sure you use proper PowerPoint design principles when compiling information (font size, alignment, proximity) Make sure your audience can read your slides.
