What does a decomposer do?
decomposers recycle nutrients and matter back into the ecosystem by breaking down living things

What does The Law of Conservation of Energy say:
energy cannot be created not destroyed
energy can only transfer to other objects or
transform into a different type of energy
400
What does the mitochondria do?
breaks down glucose to release energy in the cell
400
what is photosynthesis
photosynthesis is the process in which plants turn sunlight, carbon dioxide, and water into glucose (sugar). In this process plants also release oxygen

what is the cytoplasm, what does it do for a cell?
the cytoplasm is a gel-like substance that fills the inside of a cell. It transports nutrients inside the cell and keeps the other structures in place inside the cell.

Why is the nickel coin not magnetic?
although nickel is highly magnetic, the nickel coin is not magnetic because it is primarily made of copper not pure nickel
500
Can an object have potential and kinetic energy at the same time? explain your reasoning.
Yes an object can have both potential and kinetic energy. Think of going down a roller coaster. In the middle of the downhill you have some kinetic energy from moving. You also have potential energy from your position / height / gravity.
