The right answer is the activation energy.
The catalyst increases the reaction rate by introducing new reaction paths (mechanism), and lowering its activation energy, or activation Gibbs free energy. By doing this it can increase the speed, or lower the temperature of the reaction. It is important to note that the catalyst does not alter the total Gibbs free energy of the reaction which is a system state function and therefore has no effect on the equilibrium constant.
Answer : The correct option is, the activation energy
Explanation :
Activation energy : Activation energy is defined as the minimum amount of energy absorbed by the reactant molecules so that their energy becomes equal to the threshold energy.
During the chemical reaction, the reactants react to form product. When a catalyst is added to a chemical reaction then the reaction becomes faster that means the rate of reaction increases and the activation energy decreases.
In the given diagram, 'G' is the activation energy without catalyst and 'H' is the activation energy with catalyst.
The energy diagram is shown below.

B. radiometric dating
C. photosynthesis
D. respiration
Photosynthesis provided the Earth with an oxygen-rich atmosphere.
Earth's surface environments are highlyoxygenated from the atmosphere to the deepest reaches of the oceans, representing a hallmark of an active photosynthetic biosphere. However, the fundamental timescale of the oxygen-rich atmosphere on Earth remains uncertain, particularly for the distant future.
Scientists estimate that 50-80% of the oxygenproduction on Earth comes from the ocean. The majority of this production is from oceanic plankton drifting plants, algae, and some bacteria that can photosynthesize

Because ecosystems are densely interwoven spaces with numerous individuals who have complex relationships to one another, many ecological phenomena are challenging to analyze.
When ecological phenomena are arranged into hierarchies, it is frequently possible to create models that simultaneously include impacts from many measurement scales.
This method has been successfully used, for instance, to analyze food webs, where trophic levels correlate to levels in the hierarchy.
Since the temporal dynamics of predators, prey, and herbivores often resolve over comparable amounts of time, measuring the dynamical features of food webs can theoretically be done at the same scale.
Because ecosystems are complex, interconnected systems with numerous players and linkages between them, many ecological phenomena are challenging to analyze.
Therefore, many ecological phenomena difficult to study.
