Answer:
Explanation:
1)
HETEROTROPHS- organisms which cannot prepare their own food and dpend on producers for their dietry demands
ex-animals, fungi
AUTOTROPHS-organisms which have the pigments required to capture energy in form of sunlight or chemicals and process their own food
ex-plants, some bacteria
PHOTOSYNTHESIS-Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
2) Chloroplasts
3)Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light and prepare food
4)Stoma (also stomate; plural stomata) is a tiny opening or pore that is used for gas exchange. They are mostly found on the under-surface of plant leaves. Almost all land plants have stomata. Stomata have two main functions. First is gaseous exchange i.e. intake of carbon dioxide and release of oxygen.
5) 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy from light produces glucose and oxygen.
