h photosynthesis. Small animals including mayfly larvae eat the cyanobacteria, and small fish such as yellow perch eat the larvae. The small fish provide food for larger fish, such as walleye.
Choose the level of the food pyramid that represents the energy role of cyanobacteria in the lake ecosystem.

< The formula for density is where m = mass, v = volume, and p = density. An easy way to remember the formula is density equals love. I found this easy to remember because p = ♡ and when you think about it, if you split the heart in half through the middle like a fraction, it will make
(if you don't understand what I'm saying, try writing it out and you will be able to see what I'm talking about!)
We already know that the block is 253 g so the mass is 253 g.
To find the volume, always multiply the 3 values width, length, and height whenever you are trying to find the volume of a block.
15.24 cm x 6.64 cm x 3.56 cm = 360.25 cm³
Now plug it into the formula.³ >
