  1. Ecology Part 2: Biomes and Population Ecology

  2. Biomes • Definition: A biome is a complex of terrestrial communities that cover a large area and is characterized by certain soil and climate conditions and particular assemblages of plants and animals. • Or in simpler words- A complex community of organisms living in an ecological region that has distinctive soil conditions and climate

  3. Tundra Tropical Rainforest Temperate Deciduous Forest Taiga (Coniferous forest) Desert Savannah/Grassland Aquatic: Freshwater Aquatic: Saltwater (marine) Intertidal/estuarine The 9 biomes Complete the biome chart! Do the Biome Project!

  4. Factors that affect a biome • Biotic Factors are biological influences, such as the food that an organism eats. “Living factors” • Abiotic Factors- are factors that are physical or nonliving, such as the climate. “ Non living factors”

  5. Other terms • Habitat is where an organism lives. • A niche is the job description for an organism, how it obtains its food, or what it eats. • Adaptations: a naturally selected behavioral or physical trait that increases an organism’s likelihood of survival in its environment.

  6. Interactions • Competition is seen between organisms that are competing for the same resource. • Predators are organisms that compete for the same resources.

  7. Symbiotic Interactions • Symbiosis is the relationship between two species that are living close together. There are 3 types: • Mutual – both species benefit. • Commensalism- one organism benefits, and the other organism is not affected. • Parasitism- one organism lives on another and harms the other organism

  8. Symbiotic Interactions • Examples • Mutualism • Commensalism • Parasitism

  9. Your Turn… Commensalism Mutualism Parasitism Commensalism Commensalism Mutualism Mutualism Parasitism Parasitism

  10. Population Ecology Things that Affect Populations in the Environment • 1. Competition • 2. Predators • 3. Parasites • 4. Disease • 5. Droughts • 6. Clear Cutting • 7. Population

  11. Renewable vs. Non-renewable • A non-renewable resource is a resource that can not be replenished by natural processes. • Fossil Fuels • A renewable resource is a resource that can be replenished or regenerated naturally. • Lumber, crops

  12. Human Impacts/Terms • Land resources must be conserved to protect plants and animals. • Conservation is preserving the Earth’s resources. • Forests can be protected from deforestation, which is the loss of forest areas.

  13. Human Impacts/Terms • Fisheries are being over fished. The oceans are on their way to being depleted. • Air is being polluted by smog (chemicals in the air) and other pollutants (harmful material in the biosphere) • Freshwater is being contaminated by run-off from farming operations and chemical plants. • Biological magnification is the pollution levels increase as you go up the food chain.
