B.DI: Diversity and Interdependence (Ecology)
Module overview →- How are atoms like carbon and nitrogen reused over and over in nature?Describe how matter cycles through ecosystems in the carbon, nitrogen, and water cycles, and how living processes and human activity move and store it (Ohio's Learning Standards for Science, Biology, B.DI.2).14 min answer →
- What keeps an ecosystem stable, and how do humans disrupt it?Explain ecosystem equilibrium and succession, and describe how human activities (climate change, habitat loss, pollution, invasive species, and extinction) reduce biodiversity (Ohio's Learning Standards for Science, Biology, B.DI.2 / B.DI.3).14 min answer →

- How does energy move through an ecosystem, and why is so much lost?Trace the one-way flow of energy through trophic levels in food chains and food webs, using energy pyramids and the ten percent rule (Ohio's Learning Standards for Science, Biology, B.DI.2).14 min answer →
- What controls how large a population can grow in an ecosystem?Explain how limiting factors and carrying capacity shape population growth, and interpret exponential and logistic growth curves (Ohio's Learning Standards for Science, Biology, B.DI.2).13 min answer →
- How do the species in a community affect one another?Describe the interactions between species, including predation, competition, and the three forms of symbiosis (mutualism, commensalism, and parasitism) (Ohio's Learning Standards for Science, Biology, B.DI.2).13 min answer →
B.E: Evolution
Module overview →- What lines of evidence show that species share common ancestors?Describe the lines of evidence for evolution and common ancestry, including the fossil record, comparative anatomy, embryology, biogeography, and molecular (DNA and protein) evidence (Ohio's Learning Standards for Science, Biology, B.E).14 min answer →
- How does natural selection cause a population to change over time?Explain how natural selection acts on heritable variation so that traits affecting survival and reproduction become more or less common in a population (Ohio's Learning Standards for Science, Biology, B.E.1).14 min answer →
- What large-scale patterns does evolution produce over time?Describe patterns of evolution including divergent and convergent evolution, coevolution, adaptive radiation, and the pace of change (gradualism and punctuated equilibrium) (Ohio's Learning Standards for Science, Biology, B.E).14 min answer →
- How do we measure whether a population is evolving?Use allele and genotype frequencies, and the Hardy-Weinberg model, to describe how a gene pool stays constant or changes over time (Ohio's Learning Standards for Science, Biology, B.E.2).14 min answer →
- How does one species split into two separate species?Explain how reproductive isolation leads to speciation, the formation of new species from an existing population (Ohio's Learning Standards for Science, Biology, B.E.2).14 min answer →
