Pond B Pond C Figure 3. Representation of three experimental ponds located in the Hagen Aqualab at the University of Guelph. Ponds have one or both of two fish species: Stripey- Orange Clownfish and Black Herring. All ponds have been kept at 20°C for many years and contain large and small worms as food. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. True Felco If we add 3 Black Herring to Pond A and over time the number of Black Herring returns to 2, then the carrying capacity of Black Herring in Pond A is 5.

Energy flow or calorific flow in an ecosystem is described as an open system. Critically explain what this means with real life example.
In an ocean ecosystem, the biomass of an algal community is approximately 3000 kilograms. It can support a food chain up to 4 levels. Considering an efficiency at an average of 10% in passing on energy from one trophic level to the next level, how much biomass of the fourth trophic level can be maintained.
Questiion: A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 3,000 gC/m2/day; Primary consumers: 450 gC/m2/day; Secondary consumers: 45 gC/m2/day; Tertiary consumers: 2.25 gC/m2/day. Does this ecosystem follow Lindeman’s Law for ecological efficiency? A- No, the average efficiency is 20% B- Yes, the average efficiency is 20% C- Yes, the average efficiency is 10% D- No, the average efficiency is 10%

PoN Background Information: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus, the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and als increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The results of this program are shown in the following graph (below).

A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Based on this scenario, what is the most significant role of sea otters in the marine community? Why it’s important?
