8.Pioneer species such as lichen and moss inhabit an area after a major disturbance such as a volcanic eruption. Over time, other species are found in the disturbed area and the number of pioneer species decreases. Why does the number of pioneer species decrease?The amount of available sunlight is reduced. The pioneer species can no longer thrive.The area has more soil to support complex plants. The competition increases between organisms.The area is more susceptible to the wind. Seeds are captured in the pioneer plants and germinate at a higher rate.The temperature is not as extreme as it was following the disturbance. Fewer of the pioneer species reproduce.
Answer:
The pioneer species can no longer thrive
Explanation:
After the volcanic eruption, the natural habitat of the pioneer species got disturbed in such a way that it can be revived by any means. Hence, in absence of adequate habitable conditions it is difficult for the pioneer species to survive along the path erupt by volcanic flow. Hence, the pioneer species started inhabiting the distributed land having feasible living conditions.
How can the process of ecological succession change populations and affect species diversity within an ecosystem?
Answer: Population size and species diversity both increase during ecological succession.
Over time, more species are able to survive and become established.
Explanation:
The process of ecological succession change populations and affect species diversity within an ecosystem as the population size and species diversity both increase during ecological succession and over time, more species are able to survive and become established.
What is ecological succession?Ecological succession has been defined as the process by which plant communities develop over a period of time on the land where there was no vegetation. The succession begins with a pioneer species such as lichens, some fungi species.
Species such as lichen begins to secrete acids that begin to break the barren land into small particles. The small particles mix with lichen remains and starts soil formation. On addition of soil more diverse plant species such as bryophytes and pteridophytes grow. Later on, these plants are replaced by most diverse angiosperms. In this way, species diversity tends to increase as a result of ecological succession.
Therefore, The process of ecological succession change populations and affect species diversity within an ecosystem as the population size and species diversity both increase during ecological succession and over time, more species are able to survive and become established.

Identify the type of symbiosis described. the saguaro cactus provides food for the white-winged dove through its large fruit. the bird consumes the fruit, ingests the seeds, and then deposits the seeds in a new location.
This is an example of mutualism, a type of symbiosis in which both species benefit. In this case, the saguaro cactus provides food for the white-winged dove, and in return the dove deposits the seeds of the cactus in new locations, helping the cactus to propagate.
Mutualism plays an important role in nature, as it helps to ensure the survival of both species. In this case, the saguaro cactus needs the white-winged dove to spread its seeds and help it to propagate, while the dove relies on the cactus for food. This type of symbiotic relationship can be seen in numerous species throughout the world, and is an important factor in maintaining the balance of nature.
In addition to providing food for the white-winged dove, the saguaro cactus also offers other benefits. Its large fruit is a valuable source of nutrition for other species, such as birds, mammals, and reptiles. The cactus also provides shelter for various animals, including bats, lizards, and hummingbirds.

What are 3 things that support the theory of evolution?
Fossil evidence, biogeographical evidence, and anatomical evidence were some of the many types of evidence that Darwin utilised to support his theory of evolution by natural selection.
We'll examine a variety of sources of information to examine the evidence for evolution, including both anatomy and embryology. An evolutionary heritage can be determined by similar anatomical traits between organisms, including those that are only observable during embryonic development.
Molecule biology We can tell how closely related two creatures are by comparing and contrasting the "same" gene in those animals (i.e., a pair of homologous genes).
Biogeography - We can retrace the evolutionary history of species by looking at their geographic distribution.
Fossils - However, it confirms the existence of now-extinct species and occasionally captures potential "in-between" species. The fossil record is not a complete record of evolutionary history, forms on the path if present day species.

Explanation: Bilophodont molars have two ridges, each created by a pair of cusps that are connected by an enamel ridge, or loph. This type of molar is most often found in Old World monkeys.
Specific term is bilophodont which describes teeth with two ridges, as found in Old World-monkey molars.
The molars or molar teeth are huge, level teeth at the rear of the mouth. They are more evolved in warm blooded creatures. They are utilized principally to crush food during biting. The name molar gets from Latin, molaris sanctums, signifying "grindstone tooth", from mola, grinder and lairs, tooth. Molars show a lot of variety in size and shape across vertebrate gatherings. The third molar of people is some of the time minimal.
Alluding to molars that have four cusps arranged in two equal columns, looking like edges, or 'lophs'. This attribute is normal for Old World monkeys. The bilophodont tooth design is found in cercopithecoid monkeys in the three upper molars as well as the first and second lower molars.
With few special cases, molars were utilized to penetrate and pound the seeds. It is recommended that the improvement of bilophodont molars may be a variation by Old World monkeys to seed predation.
