  1. Mimicry __________ mimicry Palatable insects resemble brightly colored, distasteful species. non-poisonous Viceroy butterfly looks like the _____________ ___________ mimicry Unrelated protected species resemble one another. predators learn more quickly Several distasteful butterflies look alike

  2. Coevolution and Symbiosis Coevolution involves long-term mutual evolutionary character adjustments of two or more species. predator-prey interactions symbiotic relationships long-term relationships. Give an example of each: commensalism, mutualism, and parasitism

  3. Interactions Among Ecological Processes Keystone species Species that have a particularly strong effect on community composition. top predators may keep one species from outcompeting others Beavers build dams and change ecology.

  4. Succession Succession is the process of ecosystems changing from a simple to a more complex structure. primary succession - occurs in bare or open areas eutrophication(adding nutrients) of oligotrophic (poor in nutrients) lakes Lichens first, then mosses, then larger plants. secondary succession - occurs only when soil is already present

  5. Invasive Species What is meant by invasive species? Give examples of invasive species in North America, and describe the effect of each.

  6. The Nitrogen Cycle Nitrogen fixation: makes nitrogen that plants can use to make proteins Mainly from symbiotic bacteria Ammonification-nitrogen fixation that makes ______(ammonia) from ______. Denitrification- bacteria release ________into atmosphere

  7. Trophic Levels ____________- capture light energy and manufacture own chemical energy primary producers ____________- must obtain organic molecules that have been synthesized by autotrophs consumers

  8. Trophic Levels Primary consumers - herbivores Secondary consumers - organisms that feed on herbivores Detritivores - live on _________ of an ecosystem ex: Buzzard Decomposers - break down complex _____________into simpler compounds Ex: bacteria, fungi

  9. Trophic Levels

  10. Trophic Levels ______________refers to the feeding level of an organism. Organisms from each trophic level constitute a food chain. Interconnected food chains constitute a food web. ____________On average, 10% of the organic matter (energy) transfers from one trophic level to the next.

  11. Primary Productivity Primary productivity refers to the amount of organic matter produced from solar energy in a given area during a given period of time. _________ primary productivity is the total organic matter produced. _________primary productivity is the amount of organic matter produced that is available to heterotrophs.

  12. Types of Parasites-Trivial Ectoparasites live on the surface of their host (outside) ex: tick.. Endoparasiteslive inside their host ex: hookworm. Mesoparasites live part of life cycle inside and part outside. Ex: Apicomplex that causes malaria. ____________- larvae eat their host and often kill , so they are really more like predators.
