In Alaska, grizzly bears must eat 10 fish and drink up to 25 liters of water to live. A
EleoNora [17]

The fish is the limiting factor because its population <u>determines the survival and availability  of the grizzly bears.</u>

A limiting factor is  resources(biotic or abiotic) that affects or determine the availabity and growth of an organism or group of an organism within an ecosystem.

The more fish it takes, the more the liver produces urea, and kidney tubules  makes use of the urea in it tubules for urine formation in the loop of Henle. The urine formation and loss, leads to intake of water and the sequence continues.

This is an example of a biological limiting factor because the bear  predate on the fish for survival and population.

If the population of the fish drops,( <u>the limiting facto</u>r) the bear drinks less water based on above, and therefore <u>disruptions  of the ecosystem</u>.

If red foxes were to go extinct, what would be the two most likely effects on the ecosystem
wel
Red foxes are omnivores. Their diet includes small animals such as  birds, squirrels, rabbits and mice, but also berries, grasses and insects such as crickets, caterpillars, grasshoppers and beetles. Red foxes are therefore primary as well as secondary consumers, and even apex predators. Their removal from an ecosystem would most likely reduce the predation pressure on small animals and insects, and may result in population explosions of these prey animals. This in turn may result in additional pressure on the ecosystem as these animals exceed the carrying capacity, and could lead to other plant and animal species within the food web being decimated. Basically, the balance of the ecosystem would be lost until a new equilibrium can be established.

Under which type of change in the ecosystem ( fast change or slow change) would more organisms be able to survive and why?
TiliK225 [7]

Answer:

slow change

Explanation:

If the change is slow they have time to adapt. An example of a fast change is human deforestation. With their habitat suddenly removed, the organisms living there will have to find new shelter and food fast. It's likely that they'll not even be able to find anything to survive off of and die, because organisms tend to have very specific needs. For example, pandas would go extinct if bamboo was eradicated.

Freshwater fish would not be able to adapt if it was suddenly dropped into salt water. They would die. An example of a slow change would be the slow addition of salt to freshwater. Fish that are better able to survive within higher levels of salinity will be more likely to reproduce. Slowly through reproduction a new type of fish suited to salt water may be developed over several generations.
