The others are major differences

Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.

The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2

Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .

describe what happens to nutrients and matter in a biogeochemical cycle

Answers

Answer: Nutrients move through the ecosystem in biogeochemical cycles. A biogeochemical cycle is a circuit/pathway by which a chemical element moves through the biotic and the abiotic factors of an ecosystem. It is inclusive of the biotic factors, or living organisms, rocks, air, water, and chemicals. Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled. The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.

Explanation:

Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.

Nutrients move through the ecosystem in the nutrient cycle or biogeochemical cycles. This cycle is a pathway by which a chemical element moves or recycles through the biotic and abiotic factors of an ecosystem.

It is inclusive of the biotic factors, or living organisms such as plants animals, and others, as well as abiotic or nonliving such as air, soil, and water.it moves through abiotic and biotic elements such as water moves through water body to the atmosphere by evaporation and moves back to earth and hydrosphere by rain and also used by living organisms.

Thus, Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.

Which events are evidence that your brain responds to stimuli in your environment?

Answers

Answer:

Answer :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.

Step 2 The central nervous system processes information received from the peripheral nervous system.

Step 3 The central nervous system sends out the processed information to the peripheral nervous system.

Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.

Explanation:-

   There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).

   The CNS consists of the brain and the spinal cord .

   The PNS consists of all the nerves that lie outside the CNS.

   The main function of the PNS is to gather information from the sensory receptors located in our body and convey this information to the central nervous system.

   The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action
