<h2><u><em>
Types of Dispersion Patterns
</em></u></h2>
- <em>If you're hiking through a forest, you might notice that some species of plants - like certain flowers or bushes - seem evenly spaced, while others - like wild mushrooms - are clustered together in only certain parts of the habitat.
</em>
<em>
</em>
- <em>Within any given plant or animal population, or group of individuals of the same species living in the same area, individuals can be spaced in different ways called dispersion patterns. There are three types of dispersion patterns.</em>
- <em>Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. And in random dispersion, individuals are arranged without any apparent pattern.
</em>
- <em>
</em>
- <em>In natural populations, random dispersion is rare, while clumped dispersion, which we'll focus on in this lesson, is the most common pattern.
</em>
- <em>
</em>
- <em>Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. It can also be caused by social interactions between individuals. Additionally, in organisms that don't move, such as plants, offspring might be very close to their parents and show clumped dispersion patterns. Let's further examine each of these three reasons for clumped dispersion.</em>

Answer:
plasmolysis is the shrinkage of protoplast from the cell wall under the influence of a hypertonic solution.this can be observed by placing the fresh filament of spirogyra in a 10% solution of common salt.the cell undergoes exomosis.
I hope this helps
Answer:
In a community, every species interact with each other. This results in the competition among them for food and habitat. The competition is more when the resources are limited and every species compete for it. Thus the efficient species will survive and the weaker one will perish. This is known as the competitive exclusion principle.
According to this principle, two species cannot live together in the same habitat and have the same niche. Niche is the resource used by individual species and it should not be shared by many species.
If the species want to coexist in a community without any competition the niche should be different. Otherwise, it leads to evolution.
Because if resources would overlap in use, the species which less dependent on the resource will be selected for evolution. If both the species is unable to evolve and rely on the same niche, then there is rigorous competition. The species which is powerful and fit exploit the resource and this leads the other species to extinction.
This competitive exclusion principle has shown in the two paramecium species - Paramacium aurelia and Paramecium caudatum. When they are grown individually in the culture medium they thrive. But when they are grown together in the same culture medium, Paramecium aurelia extinct the Paramecium caudatum for food.
It will be absorbed through roots of the tree
