The biogeochemical cycles are:
Thermodynamic processes that end in the same process in which they
started.
They are cycles that describe the different types of energy in an ecosystem.
They are phases through which the chemical elements pass in the form of
molecules through the air and water.
Those that represent the continuous circulation of various nutrients.
support or refute the following statements based on what you learned about energy flow, biogeochemical cycling, decomposition, trophic levels, and keystone species. You may add a diagram or illustration to support your answer.
Planting mangroves is better than putting dolomite sand on the coast of the polluted Manila Bay.

After safely taking samples of some small fish, a fish-eating hawk, some pond water, some zooplankton, and a fish that preys on the small fish, they determined the average concentration of compound "Z" in each sample. The table below summarizes their data. Build a food chain that illustrates the correct trophic order in the pond. Include the concentrations of compound "Z" for each part of the chain. Describe one natural process that would cause compound "Z" to contaminate the pond's water. (Please write in complete sentences.)arrow_forward

- Find the Flaw Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick. The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. The nitrogen cycle has four steps. Denitrification is where bacteria take nitrogen from the atmosphere and convert it into a form that is usable by other biological systems. Ammonification is where nitrogenous waste is converted into ammonia.
