I think it’s erosion... not sure what you’re asking
The original source of all energy in a food web is the sun. the sun provides light energy that producers use in photosynthesis. animals eat the producers and other animals eat those animals. the energy flow goes up the web, but it all originated at the sun
1.1 Starch is used as a storage of energy as its small and insoluble.
fats and oils are also a storage in plants usually in seeds
amino acids are used to form proteins
cellulose is used in the reinforcement and creation of the cell wall
1.2 Glucose is used in respiration in plants
2.1 the subcellular structures are called Chloroplasts which contain thylakoids which contain chrophyll pigments used for photosynthesis
2.2 Carbon dioxide = water ===> glucose = oxygen
2.3 Energy is transferred from the environment during photosynthesis. energy is required as light in the light dependent stage of photosynthesis and this is gained from the sun in the environment around the plant
I hope this helps
