Parland’s alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a sp
IRISSAK [1]

Answer:

(C) The main predator of these fish is another species of fish on which alligators also prey.

Explanation:

The ecosystems are complex systems, and removing one species of them, always has a chain reaction and affects the population of the other species, be it in a positive or negative manner. In this case, the alligators prey upon fish, multiple different species. The alligators though have been removed from the ecosystem, thus the apex predator exists no more. This has opened up the top predator niche in the food chain in this particular ecosystem. The predatory fish species had no predators of its own, so its population increased, thus it needed more food, and that food was obtained by hunting the other fish species, resulting in a decline in the population of the other species of fish. Only when the carrying capacity is reached in the ecosystem for the predatory fish, the population of the other fish will stop declining.

irga5000 [103]

A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE

B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

<h3>What are Euglenas</h3>

Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.

The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed  to grow exponentially for several weeks.

Hence we can conclude that  Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE  while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
