  1. Agriculture Ecology Biology - Agriculture Science Standard I Objectives 2 & 3

  2. Ecology • the study of the RELATIONSHIPS of living things to EACH OTHER and their ENVIRONMENT(surroundings)

  3. Ecosystems • ALL of the LIVING communities of an area together withthe NON-LIVING parts of their ENVIRONMENT

  4. Parts of an Ecosystem • LIVING community (BIOTICfactors) • ENERGY input and use • NUTRIENT cycling • NON-LIVING environment (ABIOTICfactors)

  5. Ecology involves the study of the following things: • The interactions between members of the BIOTIC community (the living plants, animals and microbes) • The interactions between members of the BIOTIC community and the NON-LIVING environment • The interactions between the ABIOTIC environmental factors (such as light-temperature-moisture)

  6. Organizational Levels • Biosphere • Ecosystem • Community • Population • Organism/ Individual

  7. Organizational LevelsActivity • On one side of a blank sheet of paper illustrate and label the concept of Biosphere Biosphere Your illustration here

  8. Organizational LevelsActivity • Fold the paper in half so that your illustration is on the inside. Biosphere

  9. Organizational Levels Activity • On one side of your paper illustrate and label the concept of Ecosystem. Ecosystem

  10. Organizational OrgLevels Activity • Fold the paper in half so that the illustration of ecosystem is on the inside. Ecosystem

  11. Organizational Levels Activity • On one side of the folded piece, illustrate and label the concept of Community. Community

  12. Organizational Levels Activity • Fold the paper in half so that the illustration of community is on the inside. Community

  13. Organizational Levels Activity • On one side of your folded piece illustrate and label the concept of Population. Population

  14. Organizational Levels Activity • Fold the paper in half so that Population is on the inside. Population

  15. Organizational Levels Activity • On one side of the folded sheet illustrate and label the concept of Organism or Individual.

  16. Cycles of Matter • Water • Carbon • Nitrogen • Phosphourous

  17. WATER CYCLE WATER IN ATMOSPHERE EVAPORATION PRECIPITATION WATER /ICE

  18. Water Cycle

  19. Carbon/Oxygen Cycle CARBON DIOXIDE RESPIRATION PHOTOSYNTHESIS OXYGEN

  20. Carbon Cycle

  21. Nitrogen Cycle NITROGEN GAS NITROGEN FIXATION DENITRIFICATION ANIMALS PLANTS NITRATES

  22. Nitrogen Cycle

  23. Phosphorous Cycle

  24. Limiting Nutrient - Algae Bloom

  25. Reindeer

  26. Predator-Prey • One organisms depends on the other organism

  27. Symbiosis • “Living Together” • One species lives in close association with another species over a period of time • Avoids competition for resources • Examples: • Mutualism • Parasitism • Commensalisms

  28. Mutualism • Both organisms benefit • It is between two different organisms • Example: Crocodile Bird and the Nile Crocodile • Crocodile usually eats animals, but allows the bird to walk on its mouth • Bird cleans parasites in the crocs teeth and removes and eats scraps of food

  29. Commensalism • One organism benefits, one unharmed • Sharing space, defense, shelter food • “eating together at the same table” • Neither one will die if relationship is ended • Example: Shrimp and Sea Cucumber • The shrimp spends the day inside the intestines of the sea cucumber and at night emerges from it to feed on small crustaceans • The cucumber does not benefit from it, but is not harmed

  30. Parasitism • One organism, the parasite, secures a home on or inside another organism • The parasite is the “guest” and the other organism is the “host” • It usually harms the host and benefits the guest

  31. Trivia Time – Part 1 • This organism is a bird that eats insects that live on and irritate antelopes. The bird flies up noisily when other animals approach. • What type of symbiotic relationship does this describe?

  32. Trivia Time – Part 2 • This organism lives in the intestine of its host, feeding off the host’s blood. The host suffers from loss of blood; it becomes thin and is easy prey to diseases. • What type of symbiotic relationship does this describe?

  33. Biomes of the World Tropical Rain Forest Temperate Forest Tundra Boreal Forest/Taiga Temperate Woodland/Shrubland Temperate Grassland Mountains Savannah Desert Icecaps
