For matter to be recycled and returned to the food chain, decomposers must be present. Decomposers are the final link in a food chain. They play a very important role in the food chain and makes it a cyclic process. They eat up dead animals and plants and produce nutrients from these matter back to the food chain. Plants needs nutrients for growth while living animals take up the nutrients they need from eating plants. The nutrients from these living organisms are recycled back to the ecosystem when they die by the process called decomposition with the help of decomposers.
Saliva is not excreted by the human body.
Carbon dioxide is excreted by respiration.
Urea is excreted by urine.
Salt is excreted by sweat.
Explanation:
they all have a highly developed brain
Answer:
Energy Conservation
Explanation:
Energy Conservation involves using less energy service in an effort to reduce the amount of energy being consumed.
Julie reduces the energy she uses on a normal day by turning her lights off when they are not in use. This will save the amount of energy that would be wasted when the lights are turned on when not needed by Julie. Also, when she unplugs all electronic devices at night, energy is conserved. Julie has conserved energy in these simple acts of hers by reducing wastage, and thereby reduced the pressure on the demand for more energy. By so doing, the need for energy service is reduced which in turn would have positive impact on the environment.
Environmental quality is improved as energy conservation reduces the need for energy services.
D?!? Let me know if you get it right
