How would the introduction of a predator species affect the stability of an ecosystem?
A. The stability would not change because the new predator would
simply replace the native predator.
B. The stability of the ecosystem would increase as a result of the
introduction of a new predator species.
C. The new predator would be unable to hunt effectively for native
prey, so the stability would not change.
D. The native prey might not be able to protect itself against the new
predator, so the prey population would probably decline rapidly.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )

This is what i found on google “phytoplankton, tiny organisms that live in the ocean, are autotrophs. some types of bacteria are autotrophs. most autotrophs use a process called photosynthesis to make their food.” i hope this you for what your looking for
