Twin Rivers Unified School District Key Concepts
1.Ecology (1st Semester)
    a. Students will compare the relationship between biodiversity and habitat. (6a)
    b. Students will analyze changes within an ecosystem resulting from changes in
    climate, human activity, introduction of nonnative species, or changes in
    population size. (6b)
    c. Students will analyze examples of population dynamics. (6c)
    d. Students will interpret a diagram of the various abiotic cycles and explain how
    they affect the environment. (6d)
    e. Students will describe how energy is dispersed within a food webs and energy
    pyramids. (6f)

Note: The abbreviation CCS stands for California Content Standards referenced below.

Ecology
6. Stability in an ecosystem is a balance between competing effects. As a basis for
understanding this concept:
  1. Students know biodiversity is the sum total of different kinds of organisms and
    is affected by alterations of habitats.
  2. Students know how to analyze changes in an ecosystem resulting from changes in
    climate, human activity, introduction of nonnative species, or changes in population
    size.
  3. Students know how fluctuations in population size in an ecosystem are determined
    by the relative rates of birth, immigration, emigration, and death.
  4. Students know how water, carbon, and nitrogen cycle between abiotic resources
    and organic matter in the ecosystem and how oxygen cycles through
    photosynthesis and respiration.
  5. Students know a vital part of an ecosystem is the stability of its producers and
    decomposers.
  6. Students know at each link in a food web some energy is stored in newly made
    structures but much energy is dissipated into the environment as heat. This
    dissipation may be represented in an energy pyramid.
  7. * Students know how to distinguish between the accommodation of an individual
    organism to its environment and the gradual adaptation of a lineage of organisms
    through genetic change.

Standards that all students are expected to achieve in the course of their studies are unmarked.
Standards that all students should have the opportunity to learn are marked with an asterisk (*).
