Electromagnet: The magnet made by using electric current is called an electromagnet. The electromagnet works on the magnetic effect of current.
A simple electromagnet consisting of a coil of insulated wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. The strength of magnetic field generated is proportional to the amount of current through the winding.
Take around 75 cm long piece of insulated flexible wire and an iron nail. Wind the wire tightly around the nail in the form of a coil. Connect the free ends of the wire to the terminals of a cell through a switch. Place some pins on or near the end of the nail. Now switch on the current and the pins cling to the tip of the nail. Switch off the current. The coil in the above activity behaves like a magnet when electric current flows through it. When the electric current is switched off, the coil generally loses its magnetism. Such coils are called electromagnets. The electromagnets could be made strong by increasing the number of turns in the coil and by increasing the current passing through the coil.
These electromagnets are used in electric bells, loud speakers, electric motors, electric fans toys and telephone instruments. Electromagnets are also used in separating the non-magnetic and magnetic materials. It is used by doctors to remove tiny particles from the eyes of a person which may have fallen into the eyes accidentally.

Insectivorous plant
Some plants eat insects. Such plants are called insectivorous plants. They trap and digest the insects. Pitcher plant is the example of an insectivorous plant. In pitcher plant the leaf is modified to form a pitcher like structure. The bright colour of the pitcher makes it very attractive to insects. Inside the pitcher; there are several hair-like structures. These hairs direct the trapped insects downwards. When an insect sits on the pitcher of the plant, the lid closes and the insect gets trapped inside the pitcher. The insect is then digested by the enzymes secreted by the cells of the plants.
Saprotroph
Saprtrophs are non-green plants e.g. Agaricus (Mushroom) fungi, yeasts and bacteria. Saprotrophs get their food from dead or decaying organic matters. They grow on decaying organic matters such as cow-dung, wood, bread, etc.
Saprotrophs secrete digestive juice over the decaying materials and absorb nutrients from them. This is called Saprotrophic Mode of Nutrition.

| Autotrophic Nutrition | Heterotrophic Nutrition |
| Organisms prepare their own food using simple substances that are available in their surroundings | Organisms obtain their food by digesting organic compounds |
| Phototrophic and Chemotrophic are the two types of autotrophic nutrition | Holozoic, parasitic, symbiotic association, and saprophytic are the four types of heterotrophic nutrition |
| Plants are an example for autotrophic nutrition | Animals and some plants are an example for heterotrophic nutrition |
| Autotrophs are the producers in the food chain | Heterotrophs are the consumers in the food chain |

A lichen is an organism that results from a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. The photosynthesizer benefits from the water and nutrients absorbed by the fungus.

Green plants make their own food by the process of photosynthesis. Chlorophyll, the green pigment found in chloroplasts, traps light energy from the sun. The plant also takes in raw materials from the environment, water through its roots and carbon dioxide moves into the stomata by diffusion.

The photosynthesis equation is as follows:
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy → from light produces glucose and oxygen.
