Answer 1

HEYA !!!!!

HERE IS UR ANSWER -------------

1.Autotrophs -- The organisms that makes their own food are by photosynthesis is called autotrophs.

example ---- green plants.

2.Heterotrophs -- The organisms that can't make their own food and depend on other organisms for their food is called heterotrophs.

examples----- animals , human beings .

3.Phototropism -- It is the orientation of plant in response to light , either towards the light source ar away from it.

examples----- sunflower.

4.Photosynthesis -- It is the process by which green plants make their own food by sunlight in the presence of carbon dioxide and water.

5.Chloroplyll -- It is a green colour pigment present in green plants which is responsible for absorption of light to provide energy for photosynthesis.

Answer 2

Heya!!


Here's ur answer..



❇️ AUTOTROPHS : The living organisms which are capable of making their own food by the process of photosynthesis in the presence of sunlight.

For example. All plants and blue green algae.



❇️ HETEROTROPHS : The organisms that cannot make their own food themselves and depend on other organisms for food.

For example. Humans, animals etc.


❇️ PHOTOTROPISM : The movement of plant and its parts when sunlight acts as a stimulus.

For example. Growth of shoot towards the sunlight.


❇️ PHOTOSYNTHESIS : The process by which green plants make their food in the presence of sunlight and chlorophyll by using water and Carbon Dioxide.

Equation :

6CO2 + 6H2O ------(in the presence of sunlight and chlorophyll) ------> C6 H12O6 + 6 O2


❇️ CHLOROPHYLL : It is a green coloured pigment present in green plants (in chloroplast) which is responsible for trapping the sunlight and use it for photosynthesis.

Chlorophyll reflects the green colour from sunlight and absorbs all other colors due to which the plants look green.



Hope it helps!!
