  1. 1What is the main way we see if two organisms are the same species?
    1. Aif they can breed together
    2. Bif they can produce fertile offspring
    3. Cif they look the same
    4. Dif they live in the same habitat
  2. 2A habitat can thought of as literally where an organism [blank_start]lives[blank_end].

    A population is the number of interbreeding individuals of the [blank_start]same species[blank_end] found in an area

    A community is the number of [blank_start]various populations[blank_end] in a habitat.
    1. Alives
    2. Bbreeds
    3. Csame species
    4. Dsame phenotype
    5. Evarious populations
    6. Fall the animals
  3. 3An 'ecological niche' is how an organism gets what they need out of their environment; it means that two organisms can occupy the same habitat and not be in competition.
    1. AVerdadero
    2. BFalso
  4. 4Select the two statements that best define 'adapted' organisms
    1. Abeing able to exploit their own environmental niches
    2. Bbeing able to find food quickly
    3. Cspecific behavioural, physiological, or anatomical changes to suit their needs/environment
    4. Dhow organisms have evolved to suit their surroundings
  5. 5Behavioural adaptations are [blank_start]actions[blank_end] that help organisms to [blank_start]survive and reproduce[blank_end].

    Anatomical adaptations are the [blank_start]structures[blank_end] we see when we [blank_start]dissect or observe[blank_end] an organism.

    Physiological adaptations relate to the [blank_start]internal workings[blank_end] of organisms that help them survive and/or reproduce.
    1. Aactions
    2. Bsurvive and reproduce
    3. Cstructures
    4. Ddissect or observe
    5. Einternal workings
  6. 6Co-adaption is how a organism adapts to its environment when it changes, for example when seasons change
    1. AVerdadero
    2. BFalso
  7. 7What's the definition of the term endemic?
    1. Ahow a species is adapted to it's role in the ecosysytem
    2. Ba species who has more advantageous alleles
    3. Ca species that is only naturally found in one place
