Answer:
I'd need the data from the population sizes of the algae, walleye pollock, orca, ocean sunfish and sea turtles. And I'd also need water temperature data, levels of dissolved oxygen.
Explanation:
The jellyfish population may have increased because of an increase in phytoplankton. This leads to an increase in
zooplankton; a decrease in walleye pollock, leading to an increase in zooplankton; or an increase in orcas, leading to a
decrease in sea turtles. Sea turtles, being the main predator for keeping the jellyfish population in check.
Also, if there are more red algae, jellyfish polyps have less place to grow. Without it, the polyps can attach itself on every surface.
Answer:
The correct answer will be option-C.
Explanation:
The survivorship curves are the representation of the proportion of individuals of the given species which are alive at different ages in the population of species. The curves are represented in the form of a graph with the number of individuals plotted on the y-axis to the age of survivorship on the x-axis.
The survivorship curves are of three types: Type I, II and III out of which type three represents the population with equal probability of dying at all age groups. This is represented by a straight line on the graph.
Thus, Option-c is the correct answer.
Feeding relationships in which organisms feed on a variety of organisms is called a food web.
