Drawin's experiments are just one way to study phototroprism. A student wants to investigate the effects of phototroprsm in bean plants. She places a light source directly above one plant, at a forty-five degree angle to another, and at a ninety-degree angle from the third. What is the independent variable.

Angle of light source

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment in order to bring about a measurable response, which is the dependent variable.

In this question, a student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty-five degree angle to another, and at a ninety-degree angle from the third. This shows that the variable being manipulated (independent variable) is the ANGLE OF THE LIGHT SOURCE.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
