In a grassland, the number of antelopes increased from 200 to 400. Antelopes are grass-eating animals. How will this change directly affect the ecosystem?

A.
There will be fewer producers in the area.
B.
There will be an increase of other grass-eating animals.
C.
There will be no decomposers in the area.
D.
There will be fewer predators in the area.

answer:

B. There will be an increase of other grass-eating animals.

Explanation:

As antelopes eat grass, a increase as large as this one will most likely mean that the grass will be eaten in much larger quantities. This will have an effect both on the antelopes and on other animals. As the population of antelopes grows, animals that eat antelopes will have more food, and their population is likely to increase too. However, animals that eat grass might find less sources of food. As the antelope population continues to grow, they will eventually run out of grass. When this happens, the population will decrease. In this way, ecosystems usually manage themselves depending on the amount of food that can sustain the animals.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
