Walking Ecology Scavenger Hunt – HL Bio year 1, Topic 5.1-5.3
Name:
1. As we move to and through the Alapocas Woods trail (as far as we can get in the time
available – stay within listening distance of the teacher to hear instructions for turning around if
needed to make it back for the next class!), keep a record of observations of examples and
evidence (direct is better, but indirect is acceptable) of any of the following concepts from our
ecology unit. In order to get credit, you must have a brief description , applying the concept to
the situation accurately.
Species
Habitat
Population
Community
Ecosystem
Ecology
Autotroph
Heterotroph
Consumer
Producer
Saprotroph
Food chain
Food web
Trophic level
Energy sources
Energy flow
Decomposer
Carbon cycle
Greenhouse effect
Precautionary principle
Natality
Immigration
Mortality
Emigration
Growth curve
Limits to growth
2. Now, to begin a review for the upcoming final, also look for evidence that you can explain
which connects to the following processes that we have studied this year:
Cell theory (functions of life)
Types of cells (prokaryotic, eukaryotic, where do viruses fit in?)
Specialization (cell parts, responses to environmental, developmental cues)
growth and development (mitosis, specialization)
structure/function relationships (enzymes, carbohydrates, proteins, lipids, nucleic acids)
metabolism (DNA replication, transcription, translation, respiration, photosynthesis)
genetic variability (sources of diversity, causes of mutation, even the use of genetic technology)
natural selection (more on this next fall!!)
homeostasis (like in the carrying capacity of a population)
negative feedback (like the limitation due to food, resources, disease etc.)
specificity of enzymes (see structure function above – also in metabolism, optimization)
universiality (of codon usage in translation, played out in shared structures and functions)
redundancy (of third base in codons, played out in diversity within related individuals)
surface area to volume ratios (limits to growth of cells…what about organisms?)
regulation (switches, triggers, environmental control_
one gene one polypeptide (mutation, effect of genotype on phenotype, exceptions to this)
3. Take a trash bag and pick up along the way – be careful to pick up cleanly, using the bag
as a glove and wash your hands when you return.
