Xelga [282]3 years ago
4 0

Answer:

Changes occurs in the environmental conditions directly affect carrying capacity of the ecosystem.

Explanation:

Carrying capacity of the ecosystem refers to the capacity of the environment which adjust plants and animals in a specific atmospheric condition. Suppose in harsh winter, the temperature of the ecosystem is very low which is unbearable for most of the plant and animal species, so very low number of plants and animals are able to live in that environment. In the ecosystem where the winter is harsh and the spring is cold, the population of living organism are more decreasing. If the ecosystem has Harsh winter, Cold spring, and Hot summer, this type of environment hold very low number of living species due to high variation in the environment.

The ecology question above says : A fast swimming strong body fish such as a swimming which is adapted to clear fast and strong
Dafna11 [192]

Correct question:  A fast swimming strong body fish such as a <u>salmon</u> which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file

Answer:

Source of a river zone

Explanation:

The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.

Rivers belong to lotic environments, characterized by constant moving water.

  • Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.
  • Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom.
  • Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish.
  • Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.

Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.
