The keystone species are the one, who play a very important role in the ecosystem. In case, the keystone species is wiped off from a particular ecosystem, then  the function of the ecosystem would cease and lead to a major effect. Hence, the keystone species is very important for the survival of ecosystem.

How does the enthalpy of photosynthesis compare to the enthalpy of cellular respiration?
Dovator [93]

Cellular respiration associates oxygen with glucose within the mitochondria to generate ATP; water and carbon dioxide are generated as well. Photosynthesis utilizes energy from sunlight to produce glucose and distinct oxygen from carbon dioxide and water.

The cellular respiration uses the outcomes of photosynthesis and photosynthesis utilizes the outcomes of cellular respiration at its initial stage.

Both the process of cellular respiration and photosynthesis exhibit an equal enthalpy. Thus, the correct answer is option A.

Katena32 [7]

So let’s substitute that into the third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now we know the value of B and the value of H. Substitute this back into the second equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4: Plug all values of H, T, and B into the final equation. Total length of fish = H + T + B Total length of fish = 9 +27 + 36 = 72.
