Describe the three basic levels in an ecosystem. provide an example of each.

The three basic levels in an ecosystem are Producers, consumers and decomposers.

Producers: The green plants that make high energy molecule such as glucose (food) by the help of the sunlight is known as the producers.

Example: Plants and blue-green algae.

Consumers: The small animals that feed on the plants for their energy requirement is known as consumers.

Example: Rabbit, Goat, Cow et cetera.

Decomposers: The bacteria, fungi and other microorganism that feed on the dead and decaying animals and obtain energy from this organic matter is known as decomposers.

Example: Winter fungus.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
