Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).

The answer is d because the water naturally lowers blood pressure
Answer
secondary consumers
Explanation
Secondary consumers are organisms which eat or depend on primary consumers. Primary consumers are those organisms that feed on plants, they are mainly herbivores and occupy second trophic level.-
Scavengers are organisms that mostly consume decaying organisms or matter, such as meat or rotting plant material. They are types of carnivores, which feed on meat, however, unlike carnivores which hunt and kill their prey, scavengers consume dead animals ad plants.
Secondary consumers occupy the third trophic level and include scavengers, other carnivores, and omnivores (consume both plants and animals).
