State the difference between nutrition in plants and animals.

Name the following:
$(a)$ The process in plants that links light energy with chemical energy
$(b)$ Organisms that can prepare their own food
$(c)$ The cell organelle where photosynthesis occurs
$(d)$ Cells that surround a stomatal pore
$(e)$ Organisms that cannot prepare their own food
$(f)$ An enzyme secreted from gastric glands in the stomach that acts on proteins

Name the following: The cell organelle where photosynthesis occurs.

Why does absorption of digested food occur mainly in the small intestine?

Which raw material is responsible for the release of $O_2$ in photosynthesis?

The organisms $A$, $B$ and $C$ can obtain their food in three different ways. Organism $A$ derives its food from the body of another living organism which is called its $D$, without killing it. The organism $B$ takes in solid food by the process of ingestion, digests a part of this food and throws out undigested food in the process called $E$. The organism $C$ obtains its food from dead and decaying plants.
$(a)$ What is the mode of nutrition of $(i)$ organism $A$ (ii) organism $B$, and (iii) organism $C$?
$(b)$ What is the organism like $D$ called?
$(c)$ Name the process $E$.
$(d)$ Give one example each of organisms like $A$, $B$ and $C$.
$(e)$ What is the general name of the three modes of nutrition exhibited by organisms $A$, $B$ and $C$?
