In ecology, allogenic succession is mediated by the abiotic components of the ecosystem, while the autogenic succession refers to the succession, which is mediated by the biotic components of an ecosystem.
A volcanic eruption wiping out an entire island is an example of allogenic succession.
A soybean crop helping in nitrogen fixation, leading to the development of other species is an illustration of autogenic succession.
A tsunami devastating all the living organism in a habitat is an example of allogenic succession.
Oak trees preventing the growth of smaller sun-seeking shrubs is an example of autogenic succession.
Answer:
The statement that best describes the graph is Carla slowed down in the beginning of her trip, stopped, and then sped up.
Explanation:
Data:
Horizontal axis = time.
Vertical axis = velocity (m/s).
A line runs in straight segments
- <em>from 0 seconds 15 m/s.</em>
- <em>to 1 seconds 13 m/s.</em>
- <em>to 2 seconds 10 m/s.</em>
- <em>to 3 seconds 4 m/s.</em>
- <em>to 4 seconds 0 m/s.</em>
- <em>to 6 seconds 4 m/s.</em>
According to the data present in the graph, it can be seen that Carla starts with a speed in her career, which decreases over time. After four seconds she stops, remains stopped for one second and starts running again, with an initial speed of 4 m/s.
<em>In conclusion, the graph show Carla -who is moving- slows down until she stops, and then starts the race again.</em>
The answer to this question is b
<span>The structure of a paramecium that holds a "reserve copy" of all the cell's genes is the micro nucleus.
</span>The micro nucelus is one of the <span>two kinds of </span>nuclei the paramecium has. The other is the<span> large ellipsoidal </span>nucleus<span> called a macronucleus. Every paramecium must have at least one small </span>nucleus<span> called a </span>micronucleus. The micronucleus is a storage site for the germline genetic material of the organism.
