In the lake the biomass of plankton decreased from 65000 to 50000 kg. As a result the biomass of the lake minnows (trophic efficiency is 9 %), for which plankton is food, also decreased. How many individuals will the lake pike population decrease by (the average mass is 3.5 kg, trophic efficiency is 12 %)?

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.
A small lake is capable of supporting both bluegill and smallmouth bass. These two bony fish species compete for similar food resources. The carrying capacity of this lake for bluegill (K,) is 1,500 and for bass (Kz) is 500. After some careful measurement, we find that a is 0.5 and that ß is 0.25. We stock the lake with 250 bluegill and 750 bass. Over time, will both species be able to co-exist? If not, which one will be driven to extinction in this lake? If so, approximately how many of each species will be present? Please show math on paper and Draw Graph on paper! Please
What if we were able to restore some critical salmon habitat, like the forests surrounding the spawning streams? To test this restoration, increase K to 40,000 fish. What would that do to the MSY value? [ Select ] Does this mean you would be able to harvest more or less fish? [ Select ]
A severe winterkill seemingly killed all the trout in a lake. A decision is made to restock the lake with trout from a nearby lake. The carrying capacity of the stocked lake is estimated at 11,500 trouts and the instantaneous rate of increase of the species is estimated at 0.006. If the lake is stocked with 800 trout, how many trout will be in the lake after 55 years. Round your answer to the closet full number.
When one species is better at obtaining and holding space than another, it is competitively dominant. Based on the diagram which non-mobile (sessile) species is the dominant competitor in the intertidal? Which is second? Rank the six non-mobile species from (1) most to (6) least competitively dominant.

When hunting disrupts the balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers. Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following in completing the table below.

In the land between the lakes, Elk and Bison Prairie, we currently have 125 bison and 15 elk. These species are known to compete for some but not all of their resources. We are able to determine that the carrying capacity of the bison K1 is 200 and that the alpha (competition coefficient) is 4. The carrying capacity for Elk (K2) is 100 and the beta (competition coefficient) is 1.
Do you think all species have the same carrying capacity or different carrying capacities? ( can you site any sources used)
Lotka-Volterra Competition A small lake is capable of supporting both bluegill and smallmouth bass. These two bony fish species compete for similar food resources. The carrying capacity of this lake for bluegill (K) is 1,500 and for bass (K,) is 500. After some careful measurement, we find that a is 0.5 and that pis 0.25. We stock the lake with 250 bluegill and 750 bass. Over time, will both species be able to co-exist? If not, which one will be driven to extinction in this lake? If so, approximately how many of each species will be present? Please show the equation step by step on paper please

As a rule of thumb, about one-tenth of the energy or biomass consumed is stored at each trophic level. About how many kg of feed should it take to produce 1 kg of chicken meat that we eat? How much more energy should it take to provide you a meal of meat compared to vegetables?
As a general rule, for each jump up in trophic level, about how much does the available energy drop? Group of answer choices practically 100 percent 90 percent 10 percent 30 percent 50 percent
