A food chain is a representation of what eats what in an ecosystem.
A combination of food chains is termed as a food web.
Example of two food chains in a food web are :
Example No 1:
Plant----- Grasshopper------ Frog---snake--- bacteria
Example No 2:
Plant---- rabbits---- fox---- bacteria
In a food chain, producers are usually plants and algae which are able to make their own food. Consumers feed on the plants. In example no 1, grasshoppers are primary consumers, frogs are secondary consumers, snakes are tertiary consumers.
In example no 2,plants are producers, rabbits are primary consumers and foxed are secondary consumers.
Decomposers are organisms that feed on the dead organisms in a food chain. In both the examples of food chain, bacteria are the decomposers.
Answer: 6CO2 + 6H2O -> C6H1206 + 6O2
Explanation: This is a balanced chemical equation for photosynthesis. In photosynthesis, six molecules of carbon dioxide react with six molecules of water in the presence of sunlight to form one molecule of glucose and six molecules of oxygen. Photosynthesis is a process by which green plants manufacture their own food using sunlight. Plants cells have an organelle known as chloroplast which contains chlorophyll a green pigment that traps energy from the sun. The energy trapped by the chlorophyll is used by plants in the presence of carbon dioxide and water to drive the synthesis of glucose with the release of oxygen as the by-products.
