Answer:
Explanation:
The largest number of individuals of a species that an environment can support and maintain for a long period of time.
Vaccines help develop immunity by imitating an infection, but this “imitation” infection does not cause illness. It does, however, cause the immune system to develop the same response as it does to a real infection so the body can recognize and fight the vaccine-preventable disease in the future
The energy available for the second-level consumers is <u>4756.5 </u>kilocalories.
A trophic level is a position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.
The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.
Calculation:
Producers (475650 kilocalories) —> Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).
So, the energy available for second-level consumers is 4756.5 kilocalories.
