<h2>B) is the correct option </h2>
Explanation:
- Succinate dehydrogenase is the smallest component of electron transport chain and consists of four different subunits including FAD, 3 Fe-S centers
- It catalyzes oxidation of succinate to fumarate and electrons released transferred to ubiquinone
- Succinate dehydogenase transfer electrons from succinate to ubiquinone via FADH2 thus this complex directly links tricarboxylic acid cycle to electron transport chain
- Activity of succinate dehydrogenase is inhibited by malonate which is a competitive inhibitor as a result oxidation of succinate to fumarate will not occur and hence concentration of fumarate will decrease
Answer:
B. Resource availability sets the limit.
Explanation:
The more resources available, the higher the carrying capacity, the less resources available, the lower the carrying capacity.
For example, take a grassland. Let's say that the grassland can support 100 deers. if there was a sudden drought, causing most of the grass to die, the carrying capacity can drop down to 10. If there was suddenly constant adequate rainfall, and silt was deposited in the land, causing more grass to grow, the carrying capacity can grow to upwards of 125.

Answer:
Explanation:
A trophic level is a set of organisms who all have similar nutritional needs. In a food web, secondary consumers, such as fox and birds of prey, are on the same trophic level. How do different populations from the same trophic level interact? Different populations on the same trophic level can compete for food.
