Biodiversity contributes to a variety of ecosystem services, which can be grouped as direct, indirect, or cultural ecosystem services. Which one of the following is an example of a DIRECT ecosystem service?
O energy
O beauty
O biogeochemical cycling

energy

Explanation:

Biodiversity can be defined as the variety or variability of species of flora and fauna in an ecosystem. A larger number of plant species or flora contributes to the greater variety of crops also some of the animal or faunal species are source of food for human beings.

The biodiversity involves the distribution of energy in the form of food in an ecosystem. This circulation is facilitated by the food chain when one organism is consumed by the other. Thus the direct ecosystem service of biodiversity is the distribution of energy among the organisms.

4.) metal

"-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."
