Answer:1.)the food that you eat and the way that it affects your health

2.)Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”

6.)Most dead organic matter is eventually broken down and used by bacteria and fungi. Slime moulds are also saprophytes, as well as consuming bacteria. Examples of saprophytes are cheese mold, and yeast.

7.)Cuscuta is a parasitic plant. It has no chlorophyll and cannot make its own food by photosynthesis. Instead, it grows on other plants, using their nutrients for its growth and weakening the host plant. ... Once they are firmly attached to a host, the cuscuta root withers away.
