Answer:
2) The correct answer would be C- inefficient.
The term inefficient would be the best to describe the energy transfer between trophic levels. It is because most of the energy gets lost at a particular trophic level in the form of heat. The organism uses most of the energy available at particular trophic level for its cellular functions.
Only around 10% of the energy is transferred to the next trophic level.
3) The correct answer would be A- first step.
In any ecosystem, the producers occupy the first place as they manufacture or synthesize food from carbon dioxide and water with the help of sunlight.
Consumers (herbivores and carnivores) depend directly or indirectly on the producers to get their nutrition.
The simple food chain can be summarized as:
Producers→ Primary consumers (herbivores) → secondary consumers (carnivores) → tertiary consumers (top carnivores)

Answer:Species, in biology, classification comprising related organisms that share common characteristics and are capable of interbreeding. This biological species concept is widely used in biology and related fields of study.
Answer:
Pulmonary plague, septic plague and bubonic plague.
Explanation:
So, Yersinia pestis is a rod-shaped bacterium. This microorganism can affect humans through the flea Xenopsylla cheopis. Then, the disease can manifest in three ways: pulmonary plague, septic plague or bubonic plague.
Pneumonic plague is the form of the disease that infects the lungs and its symptoms begin abruptly two to three days after exposure to bacteria. Patients have a high fever, chills, fast heart rate and often severe headaches.
Another form of the disease is the septicemic plague and the infection spreads in the bloodstream. The most common symptoms are nausea, vomiting, diarrhea, and abdominal pain.
Finally, bubonic plague, or also known as the minor plague, is a milder form of the disease that affects the lymphatic system and its symptoms are swollen lymph nodes, fever, headache, and exhaustion.
