how human activities can cause an imbalance in biogeochemical cycling?Give atleast three examples.

In the processes of photosynthesis and cellular respiration, carbon is cycled between all major spheres on Earth. Plants obtain carbon dioxide from the atmosphere as one reactant to conduct photosynthesis. Carbon dioxide is produced by organisms as a result of carrying out cellular respiration. Activity 1 Which claim is correct about the cycling of matter and the flow of energy in the carbon cycle? A. In the ecosystem, matter flows and energy cycles. B. In an ecosystem, both matter and energy cycle. C. In an ecosystem, matter cycles and energy flows. D. In an ecosystem, both matter and energy flow.

What is the difference between a nutrient pool and a cycling pool in the processes of matter flows in ecosystems?

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. Nitrification is where ammonia is converted into…

what is the term that describes an element that is "locked away" (perhaps deep underground in a deposit) and unable to enter a biogeochemical cycle?

Explain how the carbon cycle is related to energy flow in ecosystems. SIMPLE EXPLANATION IF POSSIBLE.

Oxidative Phosphorylation (electron transport chain + chemiosmosis) What goes in? What comes out? What happens to the energy that is released? Where does each step occur? What biproducts or molecules are produced or consumed (such as NADH, FADH2, CO2, ATP/GTP, O2, so on...). How is it regulated?

Which fraction of phosphorus is available for photosynthetic organisms to directly uptake and use? Organic phosphorus in detritus Absorbed phosphorus in clay Phosphorus in minerals in rocks Soluble phosphorus in water

Create a model which accurately, in detail, depicts the potential pathways of carbon and energy in an ecosystem with the following organisms: grass, mice, snakes, and hawks (don’t forget your decomposers as well).Make sure to incorporate multiple pathways and clearly illustrate how carbon and energy flow in this ecosystem.

State the second law of thermodynamics and apply it to the energy transfer from a trophic level to the next higher trophic level in a food chain.
