2. Secondary carnivores are third-order consumers that prey upon primary carnivores.
3. Tertiary carnivores, also known as quaternary consumers, feed on secondary carnivores and are generally not eaten by other animals.

• A. 2 only
• B. 3, 4
• C. 3 only
• D. All of these

Answer 1

Answer:

D. All of these

• Carnivores occupy various trophic levels above primary consumers, illustrating the complex food webs within ecosystems.

• Each level represents a transfer of energy, with significant energy loss (typically around 90%) at each step, primarily due to metabolic processes and incomplete consumption.

• The presence and abundance of different carnivore types are indicators of ecosystem health and balance.

• The concept of 'top carnivores' highlights the apex predators that sit at the very top of the food chain in a particular ecosystem, exerting top-down control on lower trophic levels.
