Ecology: Habitats & Population Ecology: Habitats & Populations Tell whether the organism is abiotic or biotic. rabbit sunlight pebble sunflower biotic abiotic abiotic biotic Put the terms in order from smallest to largest: community, organism, ecosystem, population Organism Population Community Ecosystem Smallest Largest Tell whether the following are a single organism, a population, or a community All the ladybugs in Robbinsville, NJ Zebras All the flamingoes in Miami, Fl All the prairie dogs, hawks, grasses, population single species population community single species badgers, and snakes found on the prairie Honey bees Identify the study: direct observation, indirect observation, mark-and-recapture, or sampling Counting all the sunflowers in the field Direct observation Calculating the population of messenger pigeons by capturing and marking them, releasing them to the wild, and returning at a later date to capture Mark-and-recapture more. Using the average number of bees usually found in a hive and multiplying by the number of hives in an area. Indirect observation Counting the number of June bugs in a one square meter of a meadow and multiplying by the total area of the meadow to estimate the total number of June bugs. Sampling What is the formula for population density? Population density = # of individuals unit area Use the diagram to answer each question. C Questions: 1. How was the falcon population changing from 1994 to 1997? Increasing B A 2. Which letter marks the peak of the falcon population? Letter C 3. What was the falcon population in 1988? About 400 falcons abiotic factor or biotic factor? The living parts of a habitat The non-living parts of a habitat immigration or emigration? When organism move out of a population When organisms move into a population birth rate or death rate? The number of deaths in a population over time The number of births in a population over time species, population or community? All the members of 1 species that live in a particular area All the different populations that live together in an area A group of organisms that are physically similar and can successfully mate ecology, ecosystem, or habitat? A community of organisms along with the non-living factors The study of how living things interact with each other and their environment The environment that provides what an organism needs to live limiting factors, carrying capacity, or population density? The number of individuals in a given area An environmental factor that causes a population to decrease The largest population that an area can support Good Luck…study!
