Answer:
The elemental is required in very small amount. (Ans. A)
Explanation:
Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).
Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.
Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.
So, the adjective trace means that the elemental is required in a very small amount.

Answer:
<em>The correct option is D) the rate of photosynthesis increases and then levels off.</em>
Explanation:
Photosynthesis can be described as the process by which plants make their own food from carbon dioxide and water by using light energy from the Sun. Oxygen is produced as a by-product of this reaction.
As we increase the intensity of light, the rate of photosynthesis also increases. But after a certain time, the reaction rate will level off as there might be enough food produced or the light energy might have caused the temperature to rise which would have caused the enzymes to get denatured.
