A bilge pump is not automatically on a boat. Every boat does however have a bilge area. It is the area in a boat's hull where water collects. This area is seriously recommended to have a bilge pump in it on every boat to pump the water out of this area while on the water. Bilge's have drain plugs on the back of the boat for when you take it out of the water to fully drain it. A bilge pump is not automatically on a boat.
So by level of light you probably mean light intensity which is something that can be measured. Light intensity is usually defined as the energy hitting an area over some time period. So in the case of a plant, a higher light intensity means more packets of light called âphotonsâ are hitting the leaves.nswer 5: Click Here to return to the search form. I am not sure what you mean by level of light, but I will answer your question in to ways-in terms of the intensity of light and wavelength of light. Photosynthesis needs water, carbon dioxide, chlorophyll, light, and the right temperature.
Intensity is power per unit area. Power is energy per time. For a photon, the energy is $h\nu$. So, the intensity will be $$I=Nh\nu / A$$ if $N$ is the monochromatic photon emission rate (photons per second), $\nu$ is the frequency of the photons, and $A$ is the area these photons are hitting.
