Answer: Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Answer:
Form the cell membrane around food to create a vacuole that is kept separate from the rest of the cytoplasm while enzymes break down the food.
Independent variable in a investigation is the factor you control and change (e.g. in plant biology it could be light intensity, a concentration level of substances in added water or soil) that influence the dependent variable (in plant biology this would be the rate of photosynthesis).
There must be a number of groups to prove the influence of the independent variable on the dependent variable and trials to increase credibility of the results. Remember to include a control group where independent variable is not changed. (e.g. in measurement of light intensity on the rate of photosynthesis there must be a control where the light intensity is not manipulated to present the regular rate).
Animals' DNA will adapt to the changes, and the ones that inhabited the current ecosystem will mostly die off.
