- Bile is produced in the liver. The bile juice stored in a sac called the gall bladder. It helps in the digestion of fats. It is a greenish-yellow alkaline (basic in nature) liquid, which is stored in the Gall Bladder.
- Bile is secreted into the small intestine where it helps in the digestion of fats(lipids). It actually doesn't digest fats but breaks the fat molecules into smaller pieces to make their digestion easy. This process is called fat emulsification.

The acid that is secreted in our stomach is the hydrochloric acid (HCl). The acid is released by the parietal cells in the stomach. The acid is required for the activation of the enzymes which play role in the process of digestion. The enzyme like pepsinogen remains active due to the low acidic pH by HCl in the stomach.

- Some other species of plants known as insectivorous plants that are capable of trapping insects and digesting them. These plants are known as pitcher plants with its leaf modified as pitcher.
- The top of the leaf forms a cover which closes or opens the mouth of the modified leaf.
- The pitcher consists of hair like projections directed downwards.
- As soon as an insect lands over the pitcher the cover of the pitcher opens to swallow the insect.
- As soon as the insect gets inside the pitcher the top closes and the insect gets knotted in the hair.
- The plant then digests the insect with the help of the digestive juices secreted inside the pitcher.

Chlorophylls absorb light most strongly in the <a href="https://en.wikipedia.org/wiki/Diffuse_sky_radiation" title="Diffuse sky radiation">blue portion</a> of the <a href="https://en.wikipedia.org/wiki/Electromagnetic_spectrum" title="Electromagnetic spectrum">electromagnetic spectrum</a> as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, which it reflects, producing the green color of chlorophyll-containing tissues.

Autotrophic Nutrition:
The autotrophs acts as the producers and prepare their own food by using carbon dioxide from air, water from the roots, sunlight and chlorophyll for e.g., chromatium, rhodobacter capsulatus. Some autotrophs also prepare their food by harnessing energy from the oxidization of inorganic chemicals for e.g., methane bacteria. Two types of autotrophic nutrition are phototrophic nutrition and chemoautotrophic nutrition.
Heterotrophic Nutrition:
Some organisms which cannot prepare their own food and depend on green plants and other organisms to convert high energy into their food. Examples: protozoans, liver fluke, decomposer protists, symbiodinium on corals. These could be classified as parasitic, holozoic, saprophytic and mixotrophic.

No, Humans cannot survive only on raw, leafy vegetables, or grass. It is because the grass is rich in cellulose, which is a type of carbohydrate that humans are not able to digest due to the absence of cellulose-digesting enzymes.
