ECOSYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In an ecosystem, there are populations of deer, rabbits, grass, and pine trees. Suddenly, a fire blazes through the area, which kills all of the populations. As the months go on, new species of grass begin to take root. This attracts animals, and eventually the ecosystem is restored.What type of ecological succession happened?
A
Primary succession because it started with rocks.
B
Primary succession because there was soil to begin with, and plants existed before the disaster.
C
Secondary succession because it started with rocks.
D
Secondary succession because there was soil to begin with, and plants existed before the disaster.
Explanation: 

Detailed explanation-1: -Ecosystem equilibrium is when populations of organisms in the ecosystem are in balance, with an ecosystem being a collection of living and non-living things in an area.

Detailed explanation-2: -1: Pioneer species are the first to colonize: During primary succession in lava on Maui, Hawaii, succulent plants are the pioneer species. After weathering breaks down the lava into soil, the plants are able to take root. These plants will help to further change the soil by adding nutrients to it.

Detailed explanation-3: -Terms in this set (7) The population of rabbits will increase. In the stable food chain shown below, what would you expect to happen initially if you were to suddenly double the population of rabbits? The grass population would decrease.

Detailed explanation-4: -Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.
