Biodiversity and
HIPPO
Vocabulary Review
• Ecosystem- A community of organisms interacting with a
particular environment.
• Habitat- The environment in which a population or
individual lives; includes not only the place where a
species is found, but also the particular characteristics
of the place (e.g., climate or the availability of suitable
food and shelter) that make it especially well suited to
meet the life cycle needs of that species.
• Niche- The ecological role of a species; the set of
resources it consumes and habitats it occupies.
• Species- Population of organisms that live in an area
that mate and produce fertile offspring
What is Biodiversity?
• A measure of the variety of life, biodiversity is
often described on three levels.
• Ecosystem diversity describes the variety of
habitats present;
• Species diversity is a measure of the number of
species and the number of individuals of each
species present;
• Genetic diversity refers to the total amount of
genetic variability present.
HIPPO Activity
• Read the Student page: Prairie Chicken
Problem.
• Divide into groups of three and pick up one set
of Prairie Chicken cards.
• Take turns reading the cards aloud in your
group.
• Organize the cards into 4 or 5 major categories
of threats to the prairie chicken.
• Name each category and record what cards
were placed into each category.
• Come up with possible solutions to the different
categories of threats to the population.
