Answer 1

Answer:

Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.”

A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.

Saprotroph, also called saprophyte or saprobe, organism that feeds on nonliving organic matter known as detritus at a microscopic level.

Answer 2

Answer:

1. Only plants are capable of combining simple inorganic substances into complex organic ones capable of sustaining life. An organism which can carry out this method of nutrition is said to be autotrophic which means self-feeding. There are two types of autotrophic nutrition, chemosynthesis and photosynthesis
2. A parasitic plant is a plant that derives some or all of its nutritional requirement from another living plant. They make up about 1% of angiosperms and are found in almost every biome.
3. Saprotroph, also called saprophyte or saprobe, organism that feeds on nonliving organic matter known as detritus at a microscopic level. The etymology of the word saprotroph comes from the Greek saprós (“rotten, putrid”) and trophē (“nourishment”).
