Well, there's producers and consumers. There is also one provider that is the main source of energy for all living things which is the sun. The sun provides sunlight for the producers to make their own food through photosynthesis then consumers come and eat the producers(plants) and that gives them energy. And then predators come and eat that animal and that provides their energy.

<h2>C. The question can be tested by a systematic procedure.</h2><h3>Explanation:</h3>
A scientific question is a problem that may point to a hypothesis and support us in solving the cause for any research. A good scientific question has several aspects. It should have any true results, should be testable.
A systematic process is usually intimately connected with the decisive study.

Answer: 8hrs
Explanation:
G1 phase is the intermediate phase between the end if cell division and the beginning of DNA replication.
Thus to get the duration of the G1 phase = 1/3 × 24hrs = 8hrs
Answer:
B.) Diffusion
Explanation:
Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.
