Intro To Ecology And BiomesPresentation Transcript
Start-Up: 1. Find the definition of biotic and abiotic in your text. 2. Identify the abiotic and biotic features in this picture. 3. Is this a population or a community? 4. Describe some of the interactions shown.
Explore This Ecosystem
Ecology is the scientific study of the interactions between organisms and their environments The goal of ecology is to understand the biological principles of how natural systems operate. Note! Ecology is not environmentalism! Ecology – science, not value based Environmentalism – value based
Practice: Ecology or Environmentalism?
A population of rabbits begins to decline in number as
coyotes are introduced into the area.
2. A citizen group is formed to protest the contamination of a river by a nearby factory.
3. Climate change is causing a shift in the migration patterns of many species.
4. World fish stocks are expected to be depleted by 2050.
5. Overfishing will lead to the economic collapse of the fishing industry.
Climate Determines Ecosystem Patterns in the Biosphere -Earth’s climate patterns are produced by the uneven heating of the planet by the sun -causes a varying range of temperature, wind, and amount of rainfall
The major types of terrestrial ecosystems that cover the Earth are called biomes . The major biomes are named after their climax vegetation .
