The best statement that explains why photosynthesis is the foundation of most food webs is:

D. The producers in all ecosystems are plants.

This is because plants, through photosynthesis, convert light energy into chemical energy stored in glucose, which forms the base of the food web. Other organisms, including herbivores, carnivores, and decomposers, depend directly or indirectly on these plant producers for their energy needs. Photosynthesis is the primary process that sustains life in most ecosystems by providing the essential energy source.

content: The correct answer is B. breathing mask. A breathing mask is designed to filter the air you breathe, helping to prevent mold spores and other airborne particles from entering your respiratory system. Safety goggles are used to protect the eyes, rubber gloves are used to protect the hands, and a lead apron is used to protect against radiation, so none of these are appropriate for protecting against mold spores.

The last action that the student should perform before leaving the lab area is:

B. turn off all equipment

This ensures that no equipment is left on accidentally, which could lead to energy waste or potential safety hazards. After ensuring all equipment is turned off, the student should then proceed to clean and put away the glassware and other instruments (option C), and wash their hands (option A) to maintain hygiene. Washing the instrument and table tops (option D) is also important, but it should be done after the equipment is turned off to avoid any risk of electrical hazards.

The best units to measure the mass of the fertilizer used would be:

C. grams

Grams are the most appropriate unit for measuring the mass of fertilizers because they provide a suitable scale for common fertilizer quantities. Meters and centimeters are units of length, not mass, and milligrams, while precise, might be too small a unit for typical fertilizer measurements.
