hmmm....i don't even know the answer to your question.
Answer:
The correct answer is - D. Meerkats are at a lower trophic level in the ecosystem than eagles, and the amount of energy stored in the meerkat population is less than that in the eagle population.
Explanation:
The sun's energy is stored in plants by photosynthesis. The insects are next in the food chain of life where their energy is then given to the meerkats or other small animals once eaten. The snakes and eagle-like birds are getting their energy and food from the meerkats.
The producers (plants) produce the energy so they are the first on the pyramid of the trophic level or lowest trophic level. Next are the primary consumers which get their energy and food from the producers. The meerkats would fit into this primary consumer or secondary consumer class. At that point, the tertiary consumers or predators come in, this would be the creatures that eat the primary consumers.
Answer:
The beetle population would NOT be expected to decrease until pine population decreases in size.
Explanation:
The southern pine bark beetle is responsible for some of the most important pine forests loss in the last forty years. The insect identifies a pine of a certain advanced age and digs a hole in the bark to establish in places were sugars and starch circulate. There it lays its eggs and feeds. When larvae feed, they introduce a fungus that interrupts water and nutrients circulation between roots and leaves, causing the pine death. When the pine is completely infested or is dead, the insects move to another pine, dispersing and increasing the population size.
As the beetle population size increases, the pine population decreases, after being killed by the insects. When a pine dies, it not only stops producing food for the beetles but it also becomes susceptible to being inhabited by other species that might be predators of these beetles.
The beetles' population starts to decrease when most of the pines in the forest are dying. They hardly have available food and they are more exposed to being eaten by their predators.
The beetle population would NOT be expected to decrease until the pine population decreases in size.
It is the cycle of predator-prey, where predators population affect the dinatic of prey population, and viceversa. Populations sizes increase and decrease in these cycles. Herbivory is a kind of predation, in which the prey is a plant. In this example, the predator is the beetle and the prey in the pine.
