(Term #80: R-strategist) Definition: R-strategist refers to species that have a lot of offspring but do not spend time or energy raising the individuals. Although many will die, by having many offspring, a few will likely survive to reproduce. Explanation: A group of young caterpillars on the underside of a leaf are shown here. Butterflies are r-strategists; they lay a lot of eggs but do not raise their young. Only a few of these caterpillars will metamorphose into adult butterflies.
(Term #17: C3 plant) Definition: C3 plants are plants that have not adapted to resist photorespiration (caused by the combination of oxygen, rather than carbon dioxide, with RuBP during cellular respiration) which consumes energy and fixed carbon. Explanation: The majority of plants are C3 plants, including oak trees like the seedling shown in the photograph.
