ANSWER CORRECTLY I CHOOSE FRESHWATER
Once you’ve decided on the ecosystem, the next step is to ask questions to help you research your topic. Here are a few questions to help you: What factors are currently contributing to the decline of biodiversity in the ecosystem? Which current solutions exist to address these factors? What are the pros and cons of these solutions? How effective are these current solutions in stopping the decline of biodiversity in the ecosystem? Write four additional questions that you can address through your research.

No because scientist are still changing there mines today so they are not correct to this day

This is what a calorimeter is used for simpler ex, to measure calories in food.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
