How did you determine if your predator/prey relationship was stable? What was your dependent variable? What type of measurements or observations need to be recorded during your investigation? What was your control? How will you reduce errors? What type of calculations need to be made?

However, if the size of a prey population gets tooo small, many of the predators may not habe enough food to eat and will die... S predator-prey  population size relationship that results in both populations survivng over time, despite flucuations in the size of each one over several generatisn as described stable

Explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
