Question 27 6 pts Please read the information provided and use it to respond to all of the questions below. 3,000 6,000 Elephant population 4.000 2,000 This graph shows the population growth of African elephants over a roughly 80 year period from 1900-1980. After they were protected from hunting, the elephants in Kruger National Park showed what type of population growth? Elephants eat roots, grasses, fruit, and bark, and can consume up to 300 pounds of food in a single day. Knowing this, what level of the trophic structure are elephants? Certain species of dung beetle, spend their lives using their keen sense of smell to track down the droppings of elephants. The dung beetle retrieves its nourishment from the elephant's dung and use it to house and feed their offspring What type of interspecific relationship is this describing?

Answer 1

Ansa) The Elephant in Krugar National park show J shaped growth curve or Exponential growth curve because here elephants are protected from hunting and allowed to fluorish.The data in shown growth curve indicates that eelephants grow exponentially. Once reaching carryimg capacity the growth curve of elephant will become sigmoid shape and the graph will change into logistic growth curve.

So according to given current data the elephant growth show Exponential growth curve.

Ansb) Elephants feed on plants so it is herbivores ie, primary consumer so it is placed on second trophic level in food chain.

Ansc) Dung beetle feeding on dung of elephants illustrate the commensalism type of interspecific interaction in which only one species get benefitted (dung bettle) and other species remain unaffected (elephant.) Here dung bettle get food and shelter from elephant dung so it is benefitted but there is  no effect of dung beetle on elephant so elephant remain unaffected.
