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 with the NON-LIVING parts of their ENVIRONMENT

4. Parts of an Ecosystem LIVING community (BIOTIC factors) ENERGY input and use NUTRIENT cycling NON-LIVING environment (ABIOTIC factors)

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

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?
