  1. eCO ECOLOGY

  2. WHAT IS ECOLOGY? • LATIN “ECOS” WHICH MEANS HOME. In this case the Earth is our home. • Ecology is the study of organisms and the environment: the study of the relationships between living organisms and their interactions with their natural or developed environment

  3. ECOLOGICAL HEIRARCHY BIOSPHERE The part of the Earth’s crust, waters and atmosphere that is capable of supporting life BIOME Large regional area with same climate and vegetation throughout ECOSYSTEM All communities together with the abiotic Factors affecting them COMMUNITY Groups of populations within the same area POPULATION Several of the same species ORGANISM A single member of a species

  4. BIOSPHERE If the earth were an apple the depth of the biosphere would equal the depth of the skin on the apple!

  5. What determines where life can exist within the biosphere? ABIOTIC LIMITING FACTORS • TEMPERATURE: warmest at equator colder at poles, cooler away from surface • SUNLIGHT: greatest at equator less toward poles, less as go deeper • WATER: more water more life, Fresh? Salt? • SOIL: type, sandy less- humus (rich top soil) more • NUTRIENTS: cycling of organic molecules, more life more nutrients • pH: extremes in acidity or basicity decrease life • PRESSURE: up decreases-down increases(atmosphere and hydro) • OXYGEN: up decreases-down increases(opposite in hydrosphere)

  6. Temperature decreases Oxygen levels decreasePressure decreases Sunlight decreases Pressure increases Temperature decreases pH/salinity vary No sunlight Nutrient level decreases Temperature varies Pressure increases Water availability

  7. ECOSYSTEM RECYCLING MATTER RECYCLES CONTINUOUSLY THROUGH THE ENVIRONMENT AND ORGANISMS: TO BUILD ORGANIC MOLECULES AND MAINTAIN HOMEOSTASIS CARBON HYDROGEN OXYGEN NITROGEN PHOSPHOROUS

  8. CARBON CYCLE WHY IS CARBON NECESSARY? ALL ORGANIC MACROMOLECULES

  9. WATER CYCLE WHY IS WATER NECESSARY? Transport materials in cells; Moderate temperatures; Dissolve molecules, photosynthesis/respiration(H’s),

  10. NITROGEN CYCLE WHY IS NITROGEN NECESSARY? Build monomers of PROTEINS and NUCLEIC ACIDS DNA/RNA FLIP FLOPS Fertilizers

  11. PHOSPHORUS CYCLE WHY IS PHOSPHORUS NECESSARY? Important structural unit of LIPIDS(cell membrane); DNA(connects nucleotides) ATP! Fertilizers
