Hi there!
Active Transport - Through the use of ATP, active transport pumps molecules against a particular concentration gradient. Active transport occurs from a low concentration solute and moves to a high concentration of solute. Two examples of active transport would be endocytosis and exocytosis.
Passive Transport - Active transport is the movement of molecules down a gradient. Unlike passive transport, it goes from high to low concentration and does not require energy (such as cellular energy). Some examples would be osmosis and diffusion.
I hope this helped!

Answer:
They are heterotrophs because their food is made by other organisms.
Explanation:
Unless the organism can create their food independently via photosynthesis or chemosynthesis, they must get their food from elswehere.
In the case of mushrooms, they are scavengers/decomposers, meaning they consume energy from once living organisms, thus classifying them as heterotrophs.
Have a nice day!
Answer:
If the activity of osteclasts(which demineralize bone) exceeded osteoblast activity(production of new bone), then the bone's mineral content(and thus its mass) would decline, making it weaker.
