Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through. Second, the filtered fluid passes through the tubule wherein the filtered wastes are removed; minerals are sent back to the body, and the remaining output becomes urine.
Answer:
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.
